    Research on Mineral Deficiercies for Grazing rrurninants

    Definition of the Pr~bl~rn

    Grazin~ rc~inants in the tropic~l and sc~i-tropical regions of the world generally are less pr~juctive than those kept under temperate conditions in the r.,o~? developed countries. Re;JroGucti'J2 perfo~ance tends to be lo~", calfhood :-:;:)l"calitj' his:., 3:1d rate of grm.;t~ slo,,;. Also milk production is rela ti VG ly 10\11.

    Causes &f this low productivity are multiple. Disease can be a serious limiting fdeter, especially h~~oproto2oal diseases. Low nutritional intake 10 the se~i-arii zones durin~ the long drv perioJs ~eco~~s a severe limitinz factJr. Al.30 :::alrlutrieicn resultir:; froc l:lineral, defi~ier,cies is closely ~clated to lew re?roductive perfor~2nce and growth rates as well as : '-'~.l calfhood :::oL:"tali ty.

It is a problem tb~t requires c3r~~ul stuey c0untry-~y-country and on a continuing basis. Therefore it is i~port~nt ~hat each country, or at least each ecolo3ical zone ini~iJte a oro;ram to assess the mir.eral nutrition status of grazing ~ni~~ls, and to clet2rmine essential supplements required to correct deficienci25 in grazec forages.

    The Uni'lersity of ?lo:-ida p:-oject, AIB/tC!.-C-1l53, Has started ~ioue~ber 1, 1974. It is due to tcr::linace ~;0ve::lber 1, 1977 unless extended. The purpose of this revie' ... ~,'C.s to eV2.l:Jate progress to da.te and reco:::J...7.enci future actions relative to the ?roj~ct.

    The prir..&ry obj ec d:-.r'2 of t~is proj ec t is to detel'-line the essential r.li~eral supplements for gra:ing dni~a~ ei2ts to increase efficiancy of meat and milk produ~cion systems with l resultar.t increase in quality and quantity of food in LDes and a subsequent ir.crease in e!.:1ploy;:r:ent and inccme levels.

    More specifically it w~s the intent of the project leaders to carry out research for the following purposes:

    1. To e:ger.i~ent~11y ceter~~~ the locations of ~i:1e~al dQficienci~s, adequ.:1cies, a:1d toxicities i:1 select2d areas of Latin A.r:1ericaj

    2. To estahlish the biolo~i~~l response and econo~ic benefit of mineral supple~entation of grazing ani~Dls;

    3. To evalu2te methods of ni:1eral supple~cnt adrui:1istration for grazing cattle;

    4. To pu!Jlish and Jistribute tesearch infor:tation to sti:nulate wicespreau use of mineral supplecents.

    Assessment of Pro cress to D~te

    Excellent ?rogress has been ~3de in establishing relations with research insti tu t iC:1s in seven La tin f. . meric.J.:1 cOlmtries. Programs to determine mineral st.J.tus of gr3zing ani~als and to field test supplementation regi~es to correct deficie~cies of gra~ed forages have been developed in Brazil, Colo2bia, Costa Rica, Ecuador, EI Salvador, Guate~aln and Vene~ucla. Ho~ever, the project has not yet progress~d to the sta~e of producing "hard" cata dec:~r:-:-!inin6 the [I.oed for, cnd the economic benefits from, mineral supple".entation of ;razinG rtC'.incmts in these countries.

  • 2. Narrative Summary

    In 1974, the University of Florida ~eceived a three-ye~r contract to

    investigate the ~ineral status of grazing lives~ock in Latin America. The

    project was titled "Research in Mineral Deficiencies for Grazing Ruminants

    in Latin America: (AID/ta-c-1153). Contract progress was evaluated in 1976,

    by an external review committee, and recommerdations were made to extend the

    program for an additional two to three years. The RAC committee concurred

    on this recommendation, in March 1977, and approved of a three-year extension

    to terminatp. by November 1980. An in-depth project evaluation was conducted

    in June 1979 to assess progress in objectives and recommen~. future actions.

    The evaluation team came to the conclusion that, "The contractor recorded

    commendable achievement in project objectives but the one year remaining in

    the contract is insufficient to satisfactorily complete all of the projected

    goals for Latin America and to allow for expansion into Africa and Southeast

    Asia." Therefore, the evaluation committe~ included in their recommendations

    that the oresent project be continued a minimum of two years beyond its

    scheduled termination of October 31, 1980.

    Methods used by the contractor to accomplish objectives involved the

    reconnaissance of livestock raising areas and the recruitment of host

    country conterparts to identify conditions (Phase I), laboratory and field

    experimental programs (Phase II), and the distribution and application of

    results (Phase III). Project actions have proven that phosphorus is the

    most widespread mineral deficiency for grazing ruminants in cooperating

    countries and is more responsible than any other mineral for low reproductive

    rates. Copper and cobalt were also frequently deficient while molybdenum,

    - 2 -

  • selenium, iodine, and flourine were sometimes present in excessive amounts

    (toxic). The beneficial appli~ation of this information has been emphasized

    via on-site mineral supplementation programs, scientific progress presented

    at national and international meetings, and through national institutions

    responsible for the training of livestock specialists and extension agents.

    The results of project activities should also have considerable applicability

    to similar ecological zones in other countries.

    The reconnaissance and recruitment phase in Latin America and a few host

    countries in Africa and Southeast Asia are essentially completed (Phase I).

    The experimentation programs in Latin America are well-established and are

    being established in Africa and Southeast Asia (Phase II) which pinpoint

    mineral deficiencies and toxicities for representative areas. Phase III

    activities concerned with the actual application of knowledge generated by

    the project, have been initiated in ~ few situations but will need considerable

    more attention. This proposal for project extension is to allow for (1) the

    completion of basic phases now underway in participating countries, (2) the

    implementation of systems that insure the continual application of generated

    knowledge, and (3) improvement in the appreciation of the importance of

    proper mineral mixtures for increasing returns to livestock producers.

    Contract extension will also allow for extended research with additional

    species of ruminants.

    B. Purpose and Exoected Outouts

    1. Purpose

    The purpose of this project is to improve livestock production in the

    developing countries through the more efficient utilization of mineral

    - 3 -

  • supplements which correct deficiencies or excesses of mineral requirements.

    (Success in the project will enhance the improved well being of small owners

    of livestock in the developing countries).

    c.

    2. Exoected Outputs

    a. Mineral research techniques developed to assist LDCs in

    diagnosing and correcting mineral deficiencies and excesses in cattle,

    sheep, goats, water buffalo and a few camelidae family populations

    (Rumi nants).

    b. Identification of mineral deficiencies and toxicities by

    regions, areas, and for small atypical 10cation5.

    c. Field research programs to determine the effect of

    supplemer.tal minerals on ruminant livestock performance.

    d. Demonstration of the economical benefits from proper

    mineral supplementation and mineral products.

    e. Expansion of linkages among national and international

    research institutions which are interested in mineral nutritional programs.

    f. Dissemination of information to livestock development and

    research units on mineral deficiencies, toxicities and supple~entation

    programs, and assistance to national/regional institutions in the

    dissemination of information and application of information by livestock

    owners.

    g. Assistance of trained personnel to implement field and

    laboratory programs to diagnose mineral deficiencies and toxicities,

    and to take appropriate remedial action.

    Sionificance and Rationale for the Research ,

    1. Major Problem

    Small farms are important units to consider in actions to lessen the

    - 4 -

  • severity of hunger and poverty in developing countries. Therefore, donor

    countries and host agencies are expanding their efforts with this target

    group. A considerahle number of small farmers are owners of livestock for

    the production of meat, milk, fiber, draft power, and for security. In

    developing countries, a large percentage of the livestock is ruminants

    receiving their entire nutrients from forages anJ/or poor quality rOl'1hage

    materials. However, these feedstuffs rarely provide all of the minerals

    required by grazing ruminants and there are many reports emphasiLing the

    devastating consequences of mineral imbalances (deficiencies/excesses) on

    livestock production, worldwide. Minerals demanding the nlo~t attention from

    livestock producers because of their influence on production, reproduction,

    growth and survival rates are phosphorus, copper, cobalt, flourine, molybdenum,

    selenium, and iodine. The most economical and expeditious way of correcting

    mineral inbalances is through direct supplementation to the animals --

    supplying the proper proportions of those minerals which are deficient or

    correcting for excesses. It is generally not economically feasible to

    correct inherent mineral imbalances of forages through crop fertilization.

    2. State of the Art

    Whereas dietery requirements for major and minor (trace) minerals are

    established in the USA, the adequacy of roughage materials for meeting dietary

    requirements for minerals in developing countries either is unknown or inade-

    quately defined. Consequently, it is not possible to formulate least cost

    mineral supplements that meet mineral requirements in the developing countries.

    The proposed project with the University of Florida is designed to

    assist national and regional insitutions in characterizing mineral status of

    local feedstuffs and related mineral content in ruminants. The project will

    - 5 -

  • develop representative optimized mineral supplementation programs to correct

    these mineral problems.

    3. - Beneficiaries

    The primary beneficiary will be the small livestock owner, in the

    developing countrie~. Those who receive training under the program will

    increase their immediate value to the program and should realize longrange

    benefits as well. Due to the greater degree of worldwide coverage, infor-

    mation summarizations on mineral nutrition will make it possible to develop

    models for one region that can be useful in other regions. Primary regional

    activities are anticipated which will benefit entire regions over time by

    the diffusing of research techniques and results.

    The project has been and will continue to generate technology and

    provide technical assistance to country programs for the development of

    improved management systems for ruminant livestock. Measured benefits have

    already been reported for ongoing and completed segments of the project.

    Additional benefits to the livestock producers through increased productivity

    are expected during the next three years and a major impact on the livestock

    industry is expected within ten years from the initiation of Phase III.

    D. Professional Linkages

    Particular attention continues to be given to coordinated/collaborative

    activities with international, national and regional centers. In Latin

    America, close contact/collaboration is maintained with CIAT, CONIeIT, CATIE,

    and INCAP; while in Africa, similar associations have been established with

    ILCA and SODESP. Regional agencies in Southeast Asia, such as APHCA, are

    expressing inte~est in cooperative progrmas. As the program expands, other

    - 6 -

  • agencies expressing interest in collaborative efforts will be assisted

    within the limits of the contract.

    Under the current mineral research contract, cooperative research has

    been established by the University of Florida with the following nation~l

    and international institutions: In Bolivia, the Ministry of Agriculture; in

    Brazil, EMBRAPA, EPAMIG, Institutions in the states of Ceara, Minas Gerais,

    Mato Grosso, Sao Paulo, Rio Grande do Sul, and the Amazon Cattlemen's

    Association; in Colombia, ICA, CIAT and Caja de Credito Agrarioj in Costa

    Rica, the University of Costa Rica and CONICIT: in Ecuador, INIAP; in E1

    Salvador, the Ministry of Agriculture and the University of El Salvador; in

    Guatemala, INCAP; in Peru, IVITA and La Molina and National University of

    Peru; In Uruguay, the Rubino Veterinary Research Center; in Venezuela, the

    Centro de Investigaciones Agronomicas, Universidad Central, Universidad de

    Oriente, and Universidad del Zulia. Research with these institutions will

    be continued with the objective of developing research methodology which will

    assist thr developing countries in diagnosing and correcting mineral

    deficiencies in ruminants.

    Malawi and Senegal in Africa and Indonesia, Thailand, Malayasia, and

    Philippines in Southeast Asia are now involved with the testing and application

    of the research methodology developed for activities in Latin Am~rica. These

    systems include representative ruminant populations of cattle, sheep, goats

    and water buffalo to determine mineral problems and to develop least cost

    mineral supplement~ to correct imbalances.

    E. Utilization Plans

    Research and survey results will contribute information to more accurately

    formulate nutritionally adequate and least costs mineral supplements. This

    - 7 -

  • infurmation will be disseminated through extension bulletins, publications

    and reports prepared by national and regional agencies, the University of

    Florida and ira some instances through jointly prepared publications. Reports

    will be prepared in Spanish, Portuguese, English and/or French as appropriate.

    The national and regional agencies that have collaborated with the

    University of Florida in this project will provide the basic organizational

    mechanism and trained personnel for the utilization and application of

    research findings from the present project and in continued monitoring/

    research of national mineral supplementation programs. Also, this infor-

    mation will be transmitted to related international centers for utilization

    in the development of their research programs, and in disseminating infor-

    mation of livestock production. It is also probable that information will

    be exchanged with investigators of other AID projects such as the Small

    Ruminant-CRSP and INFIC.

    F. Management Considerations

    1. Organization and Implementation

    Personnel in the Animal Science Department at the University of Florida

    are experienced contractors and have established cooperative linkages with

    national and international institutions. These arrangements have proven

    productive. Plans are to continue cooperative research projects with

    national and international institutions in Bolivia, Brazil, Colombia, Costa

    Rica, Ecuador, El Salvador, Guatemala, Mexico, Peru, Trinidad, Uruguay and

    Venezuela.

    Countries in Africa and in Southeast Asia have been selected which

    have significant ruminant livestock populations and whose agricultural

    - 8 -

  • agency/s are interested in identifying those mineral deficiencies and

    excesses mot limiting livestock production. Countries have selected

    national and/or international research institutions which, with some

    assistance, have the facilities and competence to determine mineral content

    of soil, plant and animal tissues. The more diffic.ult analyses will be

    conducted at the University of Florida laboratories.

    This research project is specifically designed to stimulate developing

    countries in mineral nutrition. Many of the developing countries already

    have :apable scientists, highly trained ter~nicians, and well-equipped

    laboratories. The success of this project depends upon finding those highly

    trained groups which are interested in conducting research to identify and

    solve mineral deficiencies and excesses which ara limiting the production

    ca~acity of ruminants. The cont.ractor will facilitate increased interest in

    ways which minerals can and do affect livestock production.

    Steps in a successfu~l approach have been as follows: (1) correspond

    with nutritio~1sts within mineral research; (2) send them available information

    on mineral research techniques and samples of mineral research projects which

    are in progress in other countries; (3) visit them in person and discuss i~

    detail their interest, those factors most limiting their mineral research

    program and those elements which the AID-sponsored mineral research program

    might contribute; (4) assist them in developing a mineral research progl"am

    in which they are interested and wldch can reasonably be completed under

    their conditions with limited assistance from this mineral research project.

    In the current contract, the specific contributions of Latin American

    institutions compared to AID/Florida inputs have been estimated to be

    between 15 and 20:1. The AID/Florida project conducts difficult analyses

    - 9 -

  • and contributes professional expertise for design implementation and conduct

    of research as well as the interpretation of research data and assistance

    with reporting research results. This proposed project extension will also

    furnish funds for chemicals that ~re difficult to obtain. laboratory supplies

    and expendable supplies for the co11e~tion. preservation. and analysis of

    samples.

    2. Sole-Source Procurement

    This will be a sole-source procurement contract. since the project

    will be an extension of ongoing activities. and since the present contractor

    not only has demonstrated institutional compentence to execute this project,

    but also has predominant capability in minera1 nutrition in developing

    countries.

    3. Project Evaluation

    The project will be evaluated in detail by an external evaluation team

    during the second year of this contract extension. This eva1uatiQn will be

    conducted by an on-site visit composed of qualified outside consultants and

    will include at least one representative of a developing country of Africa,

    Southeast Asia or Latin America. The Development Support Buredu (DSB) will

    sponsor the evaluation team and determine the member composition. The

    evaluation will be conducted according to established guidelines and policies

    of DSB/A1D.

    G. Project Background Description

    1. General Bacr.ground

    Chemical analyses of feedstuffs gathered under the University of Florida

    Latin American Feed Composition Project (AID/csd-2498) revealed that tropical

    - 10 -

  • forages are severely deficient in several essential mineral elements. Forages

    rarely provide all the minerals required for ruminants.

    In November 1974, the University of Florida entered into a contract

    entitled "Research in Mineral Deficiencies for Grazing Ruminants in Latin

    America" AID/ta-c-1153. Phosphorus is the most widespread mineral deficiency

    for ruminants consuming tropical forages and is more responsible than any -~

    other mineral for low reproductive r~tes. In addition to phosphorus, cobalt

    and copper are likely to be deficient for ruminants in the tropics. Phosphorus

    values in 48% of 1129 forage samples were found to be 0.2 percent or less

    as reported in the Latin American 'rab1es of Feed Composition (McDowell, Conrad,

    Thomas, and Harris, 1974). Phosphorus deficiency has been reported in 35

    developing countries (McDowell, 1976), which include the major ruminant live-

    stock producing countries ~f Africa, Asia, and Latin America.

    The most devastating consequence of phosphorus deficiency throughout

    the tropical world is reproductive failure. Phosphorus deficiency produces

    a marked inhibition of the estrus cycle. Under conditions of extreme

    phosphorus deficiency, cattle may go for two or three years without producing

    a calf or even coming into estrus (Phillips, 1956; Raun, 1975). In

    phosphorus deficient areas, cows may not come into a regular estrus after

    calving until body phosphorus levels are rest0red either by feeding supple-

    mentary phosphorus or by cessation of lactation.

    Phosphorus supplementation has dramatically increased fertility levels

    in grazing cattle in many parts of the world. In two year ovservations of

    200 South African cattle, calf crops increased from 51 percent in control

    cattle to 80 percent for phosphorus supplemented cattle (Theiler, Gree and

    du Toit, 1928). Phosphorus supplementation studies in south Texas resulted

    - 11 -

  • in a weaning calf crop uf 81 percent as comoared to 58 percent for the controls

    (Black. Tash, Junes, and Ke1berg, 1943). In Brazil, phosphorus supplementation

    resulted in a 77 percent calf crop as ~ompared to 55 percent for the controls,

    (Conrad and Mendes, 1965). In the Colombian llanos, phosphorus supp1e-

    ~er.tation resulted in an 85 percent pregnancy rate compared to 50 percent for

    the controls, (Stonaker et ~, 1975).

    Phosphorus is also the most expensive mineral ingredient to purchase.

    Limited results show that phosphorus supplementation is most beneficial

    during the season of maximum forage growth. However, during the dry season,

    protein and energy are often the first limiting factors. Information on the

    effects of the frequency of supplementation and the mineral carryover with

    intermittent supplementation are not available. This information is necessary

    so that recommendations can include the mo~t economical system for feeding

    phosphorus and considerations of situations when prices are high and

    s~pp1ies are limited.

    Cobalt, cop~er. selenium, and zinc are the microminera1s most likely

    to be deficient for ruminants in developing countries. These deficiencies

    are largely restricted to ruminants which have little or no acr.:ess to

    supplementary feeds. Nineteen developing countries or regions have reported

    cobalt deficiencies while copper deficiencies have been reported in 17

    developing countries. Copper deficiencies in catt1e~ as with cobalt, occur

    mainly under grazing conditions "."lith gross sysptoms of the deficiency rare

    when con~~ntrates are fed. Deficiencies of copper can be either simple, due

    to a lac'.< of copper, or induced by excess intakes of sulfur and/or molybdenum.

    Chronic copper toxicity is almost entirely confined to sheep which indicates

    species differences in tolerances to excesses. Recent researdl Uf'~~r this

    - 12 -

  • project indicates widespread selenium and zinc deficiencies which must be more

    specifically identified during future project activities.

    Clinical signs of molybdenum toxicity are similar to copper deficiency.

    An excessive intake of molybrenum will seriously deplete copper reserves in

    cattle quickly leading to scouring, loss of condition, and other signs

    associaterl with copper deficiency. Molybdenum toxic areas characteristically

    occur on poorly drained neutral or alkaline soils which favor m~lybdenum

    Jptake by plants and reduLe the availability of copper. Both molybdenum

    toxicity and copper deficiency are corrected by providing additional copper

    to the animals ' diet.

    2. Fin( ings and Accomplishments to Date

    Research is continuing to be conducted and application methodology is

    being developed to correct problems of mineral deficiencies and/or excesses.

    Deficiencies of phosphorus, cobalt, copper. selenium, ~nd zinc are common in

    specific regions of Latin America} Asia, ana Africa. Toxicities of molybdenum.

    selenium, and fluorine also have been receiving attention in some of these

    countries. Host country institutes have been enthusiastic participants in

    all phases of the research and application programs and have been larger

    contributors than the contractors (sponsored by AID).

    Details of individual mineral research projects and of country activities

    have been comp~lerl in an Arnual Report, by the University of Florida. The

    report covers the period from March 1, 19id to June 1, 1979 and also includes

    other aspects of the contract AID-ta-c-llS3 within its 267 pages. This report

    includes:

    a. Lists of literature r~views undertaken.

    b. Citings of working relationships with technicians in LDCs.

    - 13 -

  • c. Establishment of linkages with other AID activities.

    d. Collaboration with ndtional and international ir.stitutions.

    e. Results uf mineral experimellts in specific areas.

    f. Application of experimental results to field locations.

    g. Program inputs by the contractor, host country and AID.

    h. Dissemination of infonnat.ion via seminars and symposia.

    i. Project related publications produced by the contractor.

    j. Reports presented at national and international meetings.

    k. Graduate training provided to eight developing country scientists.

  • H. Project Work Plan

    Scope of Work (Nov. 1, 1980-0ct 31, 1981)

    In the extended contr~ct period, the contractor must continue to emphasize

    collaboration with national and/or international institutes in each of the cooperating

    host countries of Latin America, Asia, and Africa. Each of the projects will

    receive guidance from one or more of the senior scientists orl the contractor's

    staff in collaboration with representatiion of host institutions, agencies, etc.

    Some of the most important items for attention during the first year have been

    identified and are set forth. Annual work plans for the second and third years

    of the project will be forwarded to the proj~ct manager before these contract

    years commence.

    A. The project will continue determinations of the mineral content

    of soil, plant and animal tissues from areas in 11 Latin American, 4

    Asian and 2 African countries where ruminant animals are of major importance.

    Both major and minor essential minerals will be studied (Ca, P, Mm, Mg, Cu,

    Co, Zn). Graduate students will be utilized on studies in their home

    territories, when appropriate. This will insure a reliable source for

    information, contribution of a personal interest ingredient, contributions

    from a host country and serve as a tOul for training purposes. In, addition,

    members of the University of Florida, Soils and Agronomy Departments will

    be consulted on special soil-plant-animal relationship abonormalities. The

    contractor will continue to identify host country counterparts parts in technical

    and administrative capacities who are responsible for daily, routine supervision

    and can alert the contractor on emergency situations.

    "

  • 1. Some of these trainees will be taught ho~ to suspect mineral problems

    in livestock units via observations on production rates as well as abnormal

    a~p~arances of plants, etc. Indicator plants will also receive attention

    and be identified.

    2. The trainees will be learning how to obtain and process reliable samples

    of biological materials for mineral content. This means the reliable collection

    of soil, plant and anim,l samples that will accurately predict the true

    mineral status of the popul~:ion or region. Samples from ami~als may include

    '~lood, liver, kidney, fat, hair etc. Most of these can be obtained from

    the live animals as wfll as carcasses. The techniques for properly obtaining

    su=h samples are extremely important as they can influence the results from

    analyses. Manuals describing these techniques are available for further distribution

    by the contractor.

    3. Technicians will be trained to handle samples during analyses and to

    interpret the results of the analyses. Dependiug upon the situation, some

    of the laboratory technicians will be trained to perform one or two ~rocedures

    such a~ grinding and weighing samples while others will be trained to completely

    analyze samples - up to the limit of the particular laboratory (this ~~ll include

    a proximate analysis in most cases plus some mineral analyses)

    The contractor will encourage the latter type of trainin6 so that the better

    trainees will eventually become trainers of future technicians.

    4. The leadership abilities of animal scientists and graduate stud~nts from

    host countries will be strengthened by improving their capabilities in mineral

    orientated activities. This will increase their respect with fellow agriculturists.

  • Contract representatives will continue to make certain that host

    country scientists know about special international meeting and are

    supplied ~ith reports on the latest developments in mineral findings

    world wide. This will strengthen the foundation knowledge for extension

    oriented activities where generated in:ormation will be prepared for

    presentation at field days, in radio talks, at seminars and during

    rap sessions.

    C. The identification, development, and continued proper functioning

    of the analytical laboratories needs constant attention by the contractor.

    The newly established laboratories must be conveniently located for reasonable

    assessability to serve the important livesto~k growing regions. The

    contractors goal is to have at least a good functioning laboratory in

    each host country.

    1. The host ~gency and the contractor will procure essential reliable

    laboratory equipment for the laboratories involved in the program. The

    host agency will purc~~be most of the equipment but the contractor will

    assist with equipment specifications, laboratory organizations and

    installation problems. Malawi and Senegal should receive considerable

    attention in this aspect.

    2. The contractor has in the past and will continue to assist developing

    countries during laboratory breakdowns, equipment irregularities, the

    translation of operating instructions, orientation of new operators and in

    solving short term deficiencies in expendibles, chemicals, and glass ware.

    These situations cannot be scheduled but are anticipated through the life

    of the contract.

    11 -~

  • The training of the laboratc~y workers ~as inc1ucied in the section

    on overall training to be provided and contir.ued.

    D. The scheduling of travel, by the contractor, will continue to be

    coordinated by the project 1e~ders to insure efficient use of time and

    resources of both the contract representatives and the scientists in the

    host countries. Therefore, a tentative schedule is proposed which will

    be adjusted to fit alterations in presently projected schedules, as the

    year progreszas.

    1. The purpose of the host country visits will be to a) expand the

    identification of competent collaboration for managing future studies

    and for training b) locate additional regions with livestock

    owners who have mineral problems affecting livestock production to refine

    area parameters, c) to encourage the sponshorship of research trials and

    recommend experimental designs for implementation by local livestock visits

    d) and to collect or advise the collaborator in the analyses of experimental data

    and interpretation of results for dissemination.

    2. A proposed schedule of travel and purposes of travel for the first

    extension year is as follows:

    November-December (2 WkR.) - Peru, Bolivia

    supplemental phosphorus and other minerals which affect animal and herd

    productivity.

    e. Research will have been conducted to determine the validity of

    different mehtodo10gies for establishing mineral status of ruminant animals.

    f. The capacities of cooperating isntitutions to r.arry out mineral

    research will have been improved.

    g. Well-controlled experiments will hal/e been completed to determine

    the effect of mineral supp1r.,llf'!ntation on grOl.,th and reproductive performance

    and on mortality.

    h. The effect of phosphorus supplementation during the rainy season

    and the carryover effect into the dry season will have been studied.

    i. Field tl'ia1~ have been conducted to study methods to counteract

    molybdenum and selenium excesses.

    j. Data will have been generated and used to design adequate mineral

    supplements for alfferent regions.

  • k. A more systematic approach will have been developed for standard-

    izing sample collection, analyses, and data reporting.

    1. Research information designed to stimulate the wide~pread use of

    mineral supplements will have been published and distributed.

    m. Evaluations of commercial mineral supplements will hav~ encouraged

    companies, researcher?, and ranchers to formulate, produce. and use high

    quality and nutritionally adequate mineral supplements.

    n. Producer oriented extension bulletins will have been published on

    mineral deficiencies and excesses for grazing ruminants (in Spanish.

    Portuguese, English and French).

    I. Researchers Competence

    The Department of Animal Science, Institute of Food and Agricultural

    Sciences (IFAS) at the University of Florida has established itself as one

    of the leading departments working in the field of tropical animal science.

    Biodata for each of the seven principal investigators can be found in the

    appendix. All have been involved in the current mineral research project

    and expect to be associated with its progress.

    J. Contributions to Institution Building

    All phases of the project will seek close cooperation with indigenous

    and international research organization. No research will be undertaken

    independent of the indigenous research organiZations. The vast majority

    of all mineral analyses will be performed in the collaborating countries

    where individuals and facilities have been identified for doing mineral

    research.

    The institutions which are cooperating in mineral research will benefit

    27

    -~-

  • in several ways. First, they will obtain analytical data illustrating

    specific areas of their countries where mineral deficiencies and/or excesses

    exist. Second, they will obtain information based on feeding trials as to

    the proper mineral supplements needed for ruminants. Third, the economic

    benefits of mineral supplementation will be clearly established. Fourth,

    the cooperating research units will have the knowledge and experience to

    continue research in minerdls for livestock after the concractor departs.

    And finally, the established operating institutions will have the potential

    to assist in the development of additional livestock mineral projects which

    cover country-wide livestock activities.

    K. Probable Benefits for the Livestock Producer

    Improvement in the levels and balances of minerals in livestock will

    increase productivity including such items as mortality, growth rates, feed

    efficiency, fertility, reproduction, milk, fiber, and work. An increase in

    production will result in a greater monetary income (saleable items) for the

    small livestock producer or an increase in animal products for personal ~

    consumption (meat, milk, etc.).

    An increase in animal productivity will r~sult in benefits to the farm

    family, from both increased income and consumable products. These benefits

    of additional cash and animal products, resulting from greater productivity,

    will improve the well being (education, medical attention, nutrition and

    sanitation) of the livestock raisers family. In addition, improvements ip

    animal productivity could take less animals to equal former production

    amounts. This would rfsult in more efficient utilization andior conservation

    of natural rescurces (native rangelands) and more efficient utilization of

    family labor.

  • This project will provide the methodologies by which LOCs and their

    agencies can implement efficient mineral supolementation programs with the

    low income livestock producers. As these programs progress, a spreading of

    technology will be duplicated from farmer to farmer, area to area, etc.

    This program can serve as a model for future thrusts into animal health and

    livestock management areas. National services will be strengthened by

    contract actions to implement practical programs for promoting economically

    beneficial practices, in the entire livestock production field. The

    successful termination point will be the establishment of effective regional

    programs by original host government agencies.

  • L-Wcmen in Develocment

    Women occupy key positions in agriculturally-oriented house-

    holds. Often, women o~~ livestock and are completely responsible

    for the processing of livestock products which are either sent

    to market or consumed directly by the family (meat, milk and

    fiber). In many countries, women or young girls also tend the

    flocks, fe~d, and care for the animals as a portion of the

    household income-earning activities. Therefore, many of the

    intended beneficaries of this program will be the female house-

    hold members who are deeply involved with livestock systems. As

    some societies in developing countries place restrictions on non-

    family male/female contacts, it is imperative that females be

    thoroughly trained as livestock production agents for effective

    promotional purposes. Opportunities for {emale extensionists

    and techni~ians of developing countries to attend workshops,

    field days, short courses and other educational sessions, should

    be developed, based on local custom, so that the materials

    presented in these sessions will reach female members of the target

    populatio

    The current research contract (AID 931-0600) has employed

    women scientists in the Animal Nutrition Laboratory of the

    University of Florida and as laboratory and/or scientific pro-

    fessionals in many developing countries. Women from developing

    countries also have been awarded scholarships for graduate

    training in project r~l~ted activities and this action will be

    :0

  • -2-

    continued. Training women a~imal scientists must assume leadership

    roles in program activities within the developing countries and these

    individuals must include both U.S. and host country citizens.

    M. ENVIRONMENTAL IMPACT/CONSIDERATION

    Initial Environmental Examination--The activities of this project

    fall into the area descrioec in Er:vironmental procedure regulations,

    Para. 216.2 (c) "Analyses, Studies, Academic or Investigative Research.

    Workshops and Meetings." These classes of activities will not normally

    require the filing of an Environmental Impact Statement or the prepara-

    tion of an Environmental Assessment. It is possible that an output of

    this project will be set of procedures, guidelines or research results

    which when used would require such assessment. However, the project

    itself only proposes research and directly supportive activities. Under

    these guidelines this activity clearly qualifies for a negative determin-

    ation at the time when a threshold decision is determined.

    N. EXTERNAL EVALUATION

    The external evaluation team report is attached (Appendix #1) which

    SUDDorts an extension of this project. Their recommendations were taken

    into consideration in the prepartion of this proposal, and are in agree-

    ment with the proposal as presented.

    The reviewers are preeminent livestock production ~pecialists and

    researchers. Dr. Glenn Beck, Chairman of the review team and former

    Vice President of Kansas State University has had extensive domestic

    and international experience in livestock production research and as an

    administrator.- Dr. Duane Ullrey, Professor of Animal Nutrition, Michigan

    State University, has held important posts in industry and in the university

    system. Dr. Juan Salazar of VECOL, Empresa Co1ombiana de Productos Veteri-

    narios, Bogota, Colombia, was selected for the team to assist with observations

    and recommendations from a person representing the recipient countries. Dr.

    Salazar has the D.V.M. degree and the M.S. and Ph.D degrees in animal breeding.

    He has occupied research and administrative positions with the Instituto

    Colombian Agropecuaro (ICA) and Caja de Credi'to Agrario. Mr. Whittle, USAID,

  • the fourth member of the review team has had numerous years of experience

    in Latin America with A.I.D. agricultural programs and was formerly a

    livestock extension specialist with the University o~ Maryland. Mr. Whittle

    is presently a member of the A.I.D. Africa Bureau.

    The project progress will be reviewed annually by the project manager

    and an external evaluatio~ team will conduct a review at the end of the

    second year of the new contract. The external evaluation team will be

    made up of eminent livestock production specialists.

    O. Past Contract Aporaisal

    Accomplishments during the present contract have been generally up to

    expectations. However, mineral supplementation trials are not as far along

    as anticipated. Acttvities during the third year (FY80) of the present

    contract will concentrate on the realization of a limited number of trials

    to determine response to mineral supplementation, and on providing technical

    assistance to national institutions in establishing their mineral supplemen-

    tation programs.

    This project is of high priority. An extension is needed to enable

    completion of the present project in Lati~ America and to expand the project

    in Africa and Southeast Asia. The extension should (a) continue to demon-

    strate the solving of nutritional problems which are depressing animal

    production, (2) continue demonstration on cast/benefit ratios derived from

    the use of correct mineral supplements, (3) broaden the emphasis on proper

    identification of mineral deficiencies and/or excesses, anu (4) assist in

    the expansion of host country sponsored nutritional research projects to

    include sheep, goats, llamas, alpacas, cattle, and water buffalo. The

    present proposal for extension ;s sound, and cost estimates are commensurate

  • with proposed work programs.

    In order to achieve the original project objectives and to make

    maximum utilization of technology and expertise development in this project,

    we strongly recommend that fundins be provided at the level suggested to

    extend this ~rogram for three more years.

    P. Financial Aspects

    1. A:O Contract Costs for Three-Year Extension

    A budget, showing estimated dollar costs for line items, for each of

    the three years is presented. Although the total amount is the same for

    each year, amounts for certain line items vary from year to year to reflect

    increases in salaries, transportation, etc., and in reduction in the purchase

    of laboratory equipment, costs for outside laboratory $ervices, etc. These

    estimates reflect increased costs for expanding the mineral research to

    Southeast Asia and Africa which increases transportation and per diem costs.

    Allowances have been inserted to assist in offsetting inflationary effects.

    Overhead has been calculated at 44.4 percent on the parts of the

    budget in accordance with the U.S. Office of Management and Budget (OMS)

    rather than salaries as in the past. Although the overhead as a percentage of

    the total budget has increased, it does conform to both the University of

    Florida and OMS's latest mandates.

  • 2. Consul tant Fees

    One or two consultants who are not University of Florida faculty may be

    used on a limited sh~rt-term ba5is so some money will be needed for consultants.

    3. Equi pment

    Several pieces of laboratory equipment must be purchaseG, shipped and

    instailed for busic laboratory procedures. The contract will assist the host

    institutions in procurenent of such items but only on a partial support basis.

    Simi'lar support will be provided through the contr1ctor when essential

    equipment is disabled. The host institutions will have to assume the major

    obligations in the p~rchase and receiving of all equipment used in the project.

    4. Laboratory and Fie1d Supplies

    Would include the following: plastic sample collecting bottles, needles.

    syringes. atomic absorption lamps (Co. Cu. Mn, Ca, Mg. Zn, Fe, Mo, and Se), dry

    ice, gas cylinders (nitrous oxide. acetylene/argon). trace mineral supplements.

    calcium and phosphorus supplements, porcelain crucibles. volumetric flasks,

    graduated cylinders, funnels, funnel supports, centrifuge tubes, wide-mouth

    bottles, test tube supports, procelain spatulas, test tubes beakers.

    volumetric pipettes, measuring pipettes, separatory funnels, cuvettes,

    pipette jars, pipette rinsers, falcon test tubes, stirring rods. wash bottles.

    Nalgene bottles, polypropylene funnels, ceramic marking ink, wax marking

    PROJECT BACKGROUh~

    Hisot:-), of the ?roiect The Florida ~~inera1 Project No. 931-0600, supportec under AID contrac:, A:D/ta-c-1153, ~as started in ~ovember, 1974. 7he project ~as revic~ed in ~ovember, 1976 by an external evalua:ion team. Folln~ing this revie~, AID extended the proj:ct an additional t~o years. It is funded unti~ ~ovecber, 1980, at ~hich ti~e it ~i11 terminate unless further extendec.

    Definition of the Probie~ Xineral deficiencies occur in most tropical and se~i-tropica1 regions c: the ~or1d. Grazing ruminants are generally less productive in these areas than in the more temperate climates. Lo~ pro-ductivity is associated with disease, low planes of nutrition, climatic stress and rn~lnutrition resulting from mineral deficiences ot imbalances. Xineral deficiencies result in lo~ reproductive performance, high mortality, slow gr~wth rates and lo~ production (milk, wool, etc.).

    Objectives of the Project The primary objective of this project is to dete~ine the essential ~ineral supplements for grazing ani=~l diets to increase efficiency of ~eat and milk production systems with a resultant increase in quality and quantity of food in LDCs and a subsequent increase in employ~ent and income levels. The specific objectives are as follows:

    1. To experi~entally determine the locations of mineral deficiencies adequacies, and toxicities in selected areas of Latin America;

    2. To establish the biological response and the econoQic benefit ~f mineral supplementation of grazing animals;

    3. To evaluate ~ethods of mineral supplement administration for grazing cattle;

    HAJOR ACCmlPLISH!1E:;!S OF THE PROJECT

    The review team evaluated the overall progress made in the Florida Xinera1 Project since it ~as started in 1974, but gave speci~l attention to the accocplishments since the previous review in 1976. It is apparent that this project has been high~y productive, not only in identifying i~ portaat dietary ~inera~ p!oblems but more importantly in developing a recognition among Latin ~eric~n countries that these problems exist and should be dealt ~ith by establishing mineral nutrition research laborat-ies a~d education porgrams.

    P.=eas icent:fyed in the 1976 revie~ as ne~::::'r.g further study and cie'Jelop~ent ore briefly highlighted in t~e fo110 ... ing sucmary.

    ~ Con:inue to s:ren2the~ the researc~ can~bilities of cooperating cou~tries in evolvi~g national mineral nutrition programs. Significant research has been initiated in 16 coopera:iDg countries, directly in-volving 185 nationals. Surveys of mineral. deficiencies and toxicities are under way, and the effectiveness of provi~ing mineral supplements directly to livestock is bein& explored in a numbe~ of locations. Leadership by the University of Florida has pl~:cd a vital role in sticula:ing cooperation among government, university and industrial personnel in seeking solutions to cineral problems in cooperating countries. Students trainei by the Univesity of Florida are returning to their home countries, thus adding their ne~ly acquired expertise to the professi .. al resou':ces cf the region.

    2. Continue to obtain more data that ~ill be useful in defining Dineral relationships a~ong soils-plants-animals. Extensive data have been collected which indicate that correlations among soil-plant-ani~al are low or non-existant for the minerals studied (Fe, ~~, Na, Zn). Liver samples collected from the most productive animals toward the end of the wet season are best for determining the mineral status of certain trace winerals in grazing animals.

    3. Establish~ent controlled eXDeriments with cooDeratin~ ranchers , = and eXDeri~e~t stations to provide more reliable information about the benefits of mineral supplementation. Controlled experiments are now ~nderway in five countries-- Bolivia, Brazil, Colombia, Peru, Venezuela. The pricary beneit~ being obtained in these experiments are improved fer-tility and increased weight gains. In one expericent, calving per~entage was increased by ~ineral supplementation from 50~ to 75:. In one experiment weight gains ~ere doubled as a result of mineral suppleQentation.

    ~. Establish experiments to ~etermine the extent of carry-over from wet to dry seascn ~rczing. Preliminary research data iro~ an experiment in Colombia indicate that major benef~ts may be obtained by feed-minerals only during the rainy season. Further exploration is needed in this area.

    5. Generate research data which can field cost: benefit ratios. Considerable data have been accumulated, but not yet analyzed which will be useful in determining cost: benefit ratios from mineral supplementation. Preli~inary infurcation indicates & return of at least double the investment in correcting cineral deficiencies.

    6. Encoura~e local ex&=dnation of mineral ~xtures. It has been observed tha: many ~ineral suprlements sold in Latin American countries a=e of poor quality, no~ ~eeting the guarantees on the labels. For example, an analysis of =ineral supplements being sold by five di:ierent cocpanies in Ecudador revealed tha: the percent of phosphorus was substantially lower than the amount guaronteed on the ~ineral label, in one case being pra~tically zero.

    8. Establish cooperative mineral research program in South-East A&ia and African Countries. Research program have be~n initiated in 3 Asian countries with more reconnaissance needed to further :~Q~tif~ appropriate locations in Africa and Asia.

    FL7URE ~EE~S fuR MINERAL RESEARCH AND :-!I~E~_U SUPPLniENTATION

    The Mineral Research Project has made consIderable progress in certain countries, and plans should be made, where feasible, to gradually turn over ~uch of the responsibility for future mineral research to scientists within those countries. Examples include Brazil, Costa Rica and Colombia. This transfer of responsibility should be preceded by an evaluation of the state of readiness of the scientists and the com=itment of the governcents in the cooperating countries. Soce assi~tance may continue to be needed in couducting difficult assays. (~ven in the United State!., few labora-tories can produce reliable determinations of se1eniu~, mo1ybdenuc and cobalt). In addition, there are some ~ifficult problems in these countries, such as "cara inchada" "ia11ing disease", and "secadera" which could be related to ~ineral inadequacies and require continuing intensive efforts to solve. It would be appropriate to set the schedule :or transfer in consul-tation with all affected parties. A three year extension of the Project may provide sufficient time for an oruerly and successiu1 transfer in those countrieS with the oost advanced programs. However, the transfer should not be tied to a~ arbitrary schedule but should proceed in a manner which will ensure that the investment to date will produce useful results.

    In a number of countries, the ~inera1 Research Project is still developing. Equipcent is not yet adequate, technicians are not yet completely trainee, and :inancial co~itments for independent support of mineral research are not fully developed. Ato~ic absorption spectrophotometry is a basic analytical technique in mineral research and involves skills that require extensive training and experience. The instrumentation is costly and requires technological support in :~e for:n of :'::;;,h quali ty ele::trical service and com-pressed gases such as acetylene, air, nitrous oxide, hydrogen, and argon. These, 0: course, are not universally available. Where the necessary ~nIrastruc:ure and trained personnel are not available, assista~r~ ~ill be required i: this i~portan: project is to succeed.

    So~e addit:onal ~uest:ons, defining a' 1S of resear::h ~hi~h have been initia:ed by the university 0: Florida an. that warrant deve10p~ent, include the :f ollo.:ing:

    1) Can certain ~ineral supple~ents be provided successfully on an inte:~ittent basis to reduce cost, as compared to continuous acbi:lis t ration?

    2) Can lo~ cost ~ineral sour:es, such as slag, be ijent::ied and successfully used as supplements?

    3) Can ~ineral supplements containing potentially toxic levels of other ele~ents be i~d safely by using Lhem for short periods C~ by ieecing an antagonist to the toxic element(s) simultaneously?

    4) '~at is the cause a~d prevention of "cara inchada"?

    5) '~"hat is the cause and prevention of "secadera"?

    Other proble~s and other countries have been tentatively explored concerning application of the Sllce cooperative techniques in improving livestock production through cineral research. The Unlversity of Florida tea~ me~bers are well-qualified professionals, have ext~nsive on-site ex-perience, have a record of goon judgement, and would be expected r.o provide real assistance to those countries that are willing to cooperate in helping the~salves.

    RECOt-L:1ENDAIIONS

    With AID support the University of Florida has developed a research system that has been unusually effective in obtaining toC involvement. Much has been accocplished with a relatively small investment of u.s. funds because of the cooperative support from each of the 16 countries involved. ~ineral deficiencies have been demonstrated in ea~h country. Government o::icials have been persuaded that this is a problem seriously reduci'16 livesto~k production and is one that can be corrected through prop~~ application of research and t~chnology. They have responded by estdr~ishing research laboratories for investigating ~ineral deficiencies. Scientists and techni:ians have been trained. Closer working relationships between research and extension agencies have been stimulated. Linkages have evolved between L.A. (and to a lesser degree Asia and Africa) and U.S. scientists and a~ong scientists froe many Latin American countries that will have long lasting benefi:ial effects.

    The review tea~ recognizes that there must be a termination point for
