    CHAPTER ONE: INTRODUCTION

    Background

    In East Africa, small ruminants play an important role in the livelihoods of rural poor farmers through

    the provision of food and household income (Verbeek et al., 2007). This largely stems from easy

    accessibility, high fertility and fecundity rates, prolific, early maturity and adaptability to different

    environments (Winrock International, 1983).

    In Rwanda, goats and sheep have an essential and overaching role in buttressing the lives of farmers.

    In 2007, the country had 1,270,903 goats and 371,766 sheep (MINAGRI, 2007). Optimal

    productivity of small ruminants is seldom reached in most developing countries mainly as a result of

    gastro-intestinal parasitosis. Gastrointestinal infections are responsible for significant losses globally

    particularly in the developing world where climatic conditions are conducive for their replication and

    multiplication (Waller, 1997).

    Haemonchosis (caused by Haemonchus) is primarily a disease of tropical and sub tropical regions,

    this parasite has adapted to conditions ranging from tropical areas to cold, mountainous regions.(Dorny, et al., 1996;Eckert and Hertzberg, 1994;Newton, 1995). However high humidity, atleast in

    microclimate of the faeces and the herbage isalso essential for larval development and their survival.

    It is a serious health problem, which causes lowerproduction due to high morbidity, mortality and

    cost oftreatment and control measures. The frequency andseverity of the disease largely depends on

    the rainfall in any particular area. Surveys in countries around theworld have shown that amongst

    domestic animals, sheep and Goats suffer more frequently from haemonchosis (Maqsood et al.,

    1996); Nwosu et al., (2007); Tariq et al., (2008). The disease caused by this parasite (Haemonchus) is

    prevalent wherever, sheep and goats are raised, but it exerts the greatest economic losses in temperate

    and tropical regions (Blood et al., 1979). An overall loss of 23.8% in meat and 40% in wool

    production has been reported in young sheep (Hussain and Akram, 1967). Apart fromHaemonchus

    contortus there are other helminthes that can be found in small ruminants the most important of these

    are Ostertagia circumcincta, Trichostrongylus axei, and intestinal species of Trichostrongylus,

    Nematodirus sp, Bunostomum trigonocephalum, and Oesophagostomum columbianum. Cooperia

    curticei, Strongyloides papillosus, Trichuris ovis, and Chabertia ovina also may be pathogenic in

    sheep.

    Small ruminant animals are adapted to different climates and the most varied conditions.

    Unfortunately, worm diseases are a major problem interfering with their production. A precise

    knowledge of the impact of infestation by haemonchus helminthes are the prerequisite to a better

    management of the infestation. This research proposal is about study of the prevalence of

    haemonchus helminthes in Nyagatare District at Nyagatare.

    1.1 Problem statement

    In Rwanda, the livestock and animal husbandry in general is considered as a very important

    component of national economy. Generally animal husbandry development particularly small

    ruminants meet many constraints such as those due to infestation by gastrointestinal helminthes.

    Haemonchus contortus is known to adapt well to even harsh conditions, which makes it more

    difficult to eliminate. (Jacquiet, et al. 1998; White and Newton, 2001). Anemia and edema, or

    swelling, are key damages caused by this parasite. TheHaemonchus contortusparasite can consume

    up to a tenth of an animals total blood volume in a day. Anemia is most easily identified in small

    ruminants by the color of the mucous membranes, particularly those in the lower eyelid. A normal

    animal will have healthy, red mucous membranes, while one heavily burdened with Haemonchuswill

    exhibit light pink or white membranes. Edema may also occur in animals heavily burdened with

    Haemonchus. This accumulation of fluid will be most obvious as a swelling in the lower jaw, a

    condition known as bottle jaw.

    Because of the above effect there is need to conduct a study on prevalence of haemonchus in Goats

    and sheep at Nyagatare District.

    1.3 Objectives

    The general objective:

    To determine the prevalence of haemonchus in goats and sheep raised in Nyagatare District, at

    Nyagatare Sector.

    The specific objectives are:

    To compare the level of infestation between sheep and goats, To compare the level of infestation of haemonchus in different sexes, and age group

    1.4 Research question

    Is there difference of infestation of haemonchus according to sexes or ages groups.

    Is there the difference of infestation of haemonchus between Goats and Sheep.

    1.5 Justification

    Raising sheep and goats in Africa and other continents generally and Rwanda particularly play a

    significant role in the food chain and overall livelihoods of rural households, where they are largely

    the property of women and their children. These animals can be reared for various reasons such as

    income generation, religious purpose, household consumption and hobby and as security against crop

    failure. The infection of haemonchus contortus parasites in those animals can cause significant

    economic loss leading to the poor health, reduced growth, and mortality of kids.

    There is little research done in Rwanda particularly about sheep and goats, so a need to determine

    prevalence and to establish the presence ofhaemonchus contortus in Nyagatare District at Nyagatare

    Sector.

    CHAPTER TWO: LITERATURE REVIEW

    2.1 General aspect on haemonchus

    2.1.1 Etiology

    Haemonchosis caused by Haemonchus contortus is a predominant, highly pathogenic and

    economically important disease of sheep and goats (Mortensen et al., 2003). These parasites are

    commonblood feeders that cause anemia and reducedproductivity and can lead to death in heavily

    infectedanimals (Githigia et al., 2001). It has been estimatedthat each worm sucks about 0.05 ml of

    blood per dayby ingestion (Urquhart et al. 2000).

    Microscopically, the male has asymmetrical dorsal lobe and barbed spicules; the female usually has a

    flap vulvae. In both sexes there are cervical papillae and a tiny lancet inside the oral capsule (Taylor

    et al., 2007).

    2.1.2 Life cycle

    Sheep and goats are generally affected by the same parasites, although certain parasites may affect

    one species more severely than the other, and treatment methods may vary between sheep and goats.

    Haemonchus contortus has a lifecycle that takes approximately 21 days to complete. The cycle

    begins when the larvae in the infective Larva stage3 (L3) of development are ingested from the grass

    and travel to the abomasum, or true stomach, of the host. Once in the abomasum the larvae will

    follow one of two paths. They may proceed with further larval stages and the eventual developmentinto adults, or they will go into hypobiosis. This is an arrested development state that occurs when

    conditions are not conducive for the entire life cycle to be complete.

    When the L3 stage larvae enter the abomasum, provided that environmental conditions are favorable,

    they will molt into the L4 stage of larval development and will then molt once more into adults.

    Factors that induce the molting of the L4 larvae into adults include: greening of grass, a rise in5

  • 7/31/2019 HABUMUGISHAProposal nyayo corrigee

    13/25

    environmental temperature, rain following a drought period, increased estrogen levels in the host, and

    possible even a photoperiod stimuli. Once the molt into an adult form is complete adults then begin to

    lay eggs in the abomasum. During hypobiosis the L4 larvae hibernate in glands in the abomasum

    without developing further or causing problems for the host. They remain metabolically inactive until

    they receive signals that indicate it is time for them to resume development and then begin to lay

    eggs. The signals that spur the L4 larvae to come out of hypobiosis are the same signals mentioned

    above that indicate to them to develop in the first place. Once larvae leave hypobiosis, they resume

    the normal lifecycle and begin to lay eggs. Haemonchus adults require about 14 days to begin laying

    eggs in the stomach after reaching adulthood. TheHaemonchus adult female can lay up to 5,000 eggs

    per day, and it is so difficult to control and so dangerous to sheep and goats. Females that have gone

    through hypobiosis over the winter generally resume development two to four weeks prior to lambing

    or kidding and begin to produce eggs. This phenomenon is called the periparturient rise in fecal egg

    counts. The eggs laid in the abomasum are expelled from the body via the feces. Eggs in the feces

    generally remain inactive for a few days in the environment, until the environment and temperature

    become favorable for the development of these eggs into larvae. The larvae hatch from the egg and

    then emerge from the pellets and move through larval stages L1, L2 and L3 of development. Once the

    larvae reach the L3 stage, the infective stage, they emerge from the fecal pellet and climb up onto

    blades of grass where they wait to be ingested by a grazing animal, thus completing the life cycle.

    2.1.3 Epidemiology

    Because larval development of Haemonchus contortus occurs optimally at relatively high

    temperatures, haemonchosis is primarily a disease of small ruminants in warm climates. However,

    since high humidity, at least in the microclimate of the faeces and the herbage, is also essential for

    larval development and survival, the frequency and severity of outbreaks of disease is largelydependent on the rainfall in a particular area (Dunn, 1992).

    The sudden occurrence of acute clinical haemonchosis appears to depend on two further factors.

    First, the high feacal worm egg output of between 2,000 and 20,000 eggs per gram (e.p.g), even in

    moderate infections, means that massive pasture populations of L3 may appear very quickly. Second,

    in contrast to many other helminth infections, there is little evidence that goats and sheep in endemic

    6

  • 7/31/2019 HABUMUGISHAProposal nyayo corrigee

    14/25

    areas develop an effective acquired immunity toHaemonchus contrortus, so that there is continuous

    contamination of the pasture (Taylor et al., 2007).

    In tropical areas such as East Africa, no significant degree of hypobiosis has been observed and this

    may be due to more frequent rainfall in this areas making such an evolutionary development

    unnecessary (Urguhart, 1989). The survival ofHaemonchus contortus infection on tropical pastures

    is variable depending on the climate and degree of shade, but the infective larvae are relatively

    resistant to desiccation and some may survive for 1-3 months on pasture or in faeces (Marquardt,

    2000).

    2.1.4 Pathogenesis

    Essentially the pathogenesis of haemonchosis is that of an acute hemorrhagic anaemia due to the

    blood-sucking habits of the worms. Each worm removes about 0.05 ml of blood per day by ingestion

    and seepage from the lesions so that a sheep or a goat with 5000 Haemonchus contortus may loose

    about 250 ml daily.

    In acute haemonchosis, anemia becomes apparent for about 2 weeks after infection and is

    characterized by a progressive and dramatic fall in the packed red cell volume. When the females are

    affected, the consequent agalactia may result in the death of the suckling animals (Dunn, 1992). At

    necropsy, between 2,000 and 20,000 worms may be present on the abomasal mucosa which shows

    numerous small hemorrhagic lesions. The abomasal contents are fluid and dark brown due to the

    presence of altered blood. The carcass is pale and oedematous and the red marrow has expanded from

    the epiphyses into the modularly cavity. Less commonly, in heavier infections of up to 30,000

    worms, apparently health sheep or goats may die suddenly from severe hemorrhagic gastritis (hyper

    acute haemonchosis). Perhaps as important as acute haemonchosis in tropical areas is lesser known

    syndrome of chronic haemonchosis. The continual loss of blood from small persisting burdens of

    several hundred worms is sufficient to produce clinical signs associated primarily with loss of weight,

    weakness and in appetence rather than marked anaemia (Urguhart, 1989).

    2. 1. 5 Clinical signs

    7

  • 7/31/2019 HABUMUGISHAProposal nyayo corrigee

    15/25

    In hyperacute cases, the animals die suddenly from hemorrhagic gastritis .Acute haemonchosis is

    characterized by anaemia, variable degree of oedema, of which the submandibular form and ascites

    are most easily recognized, lethargy, dark coloured feaces and falling wool. Diarrhea is not generally

    a feature. Chronic haemonchosis is associated with progressive weight loss and weakness, neither

    severe anaemia nor gross oedema being present (Tayloret al., 2007).

    2.1.6 Diagnosis

    The history and clinical signs are often sufficient for the diagnosis of the acute syndrome especially if

    supported by fecal worm eggs counts. At Necropsy, attention is centred on both the abomasum and

    the marrow changes in the long bones are also useful.

    In hyperacute haemonchosis, only the abomasums may show changes since death may have occurred

    so rapidly that marrow changes are minimal (Hall, 1996).

    Diagnosis of chronic haemonchosis is more difficult because of the concurrent presence of poor

    nutrition and confirmation may have to depend on the gradual disappearance of the syndrome after

    anthelmintic treatment (Marquardt, 2000).

    2.1.7 Treatment

    When acute outbreak has occurred the small ruminants should be treated with one of the derivative of

    Benzimidazoles, Levamizole or Ivermectin and immediately moved to pasture not recently grazed by

    goats. When the original pasture is grazed again, prophylactic measures should be undertaken, as

    enough larvae may have survived to institute a fresh cycle of infection. Chronic haemonchisis is dealt

    with in similar fashion. If possible the new pasture should have a good nutrition value; alternatively

    some supplementary may be given (Urguhart, 1989).

    8

  • 7/31/2019 HABUMUGISHAProposal nyayo corrigee

    16/25

    2.1.8 Control

    In the tropics and subtropics, this varies depending on the duration and number of periods in the year

    when rainfall and temperature permit on pasture a high level ofHaemonchus contortus larvae to

    develop. At such times, it may be necessary to use an anthelmitic at intervals of 2-4 weeks depending

    on the degree of challenge.

    Goats are treated at least once at the start of the dry season and preferably also before the start of

    prolonged rain to remove persisting hypobiotic larvae whose development could pose a future

    threat .For this purpose, one of the modern Benzimidazoles or Ivermictin is recommended (Tayloret

    al., 2007).

    2.1.9 Economic Importance

    The major problem lies within the agricultural industry. These parasites cause great economic losses

    in domestic animals, specifically sheep, and goat. BecauseHaemonchus contortusis a blood sucker,

    it can induce anemia and edema. Also, the hemolytic proteins that the parasite releases can lead to

    other intestinal disturbances. The host will often die with major infections. And then the Haemonchus

    contortus exerts greatest economic losses in temperate and tropical regions (Blood et al., 1979). An

    overall loss of 23.8% in meat and 40% in wool production has been reported in young sheep (Hussain

    and Akram, 1967).

    2.1.10 Prevalence of haemonchus from other researchers

    On epidemiology study of haemonchosis in sheep and goats under different managemental

    conditions, studies were performed at various Abbattoirs, livestock farms and veterinary

    hospitals in the districts of Lahore, Gujranwala, Sheikhupura and Kasur in Punjab province.Post-mortem examinations of slaughtered animals were carried out and abomasa were checked

    for the presence of the parasites. The date of collection, the number of total and infected

    animals was recorded, the age sex, area of such animals was also maintained. During the

    studies the seasonal prevalence was recorded. For this purpose the year was divided into 4

    seasons as follows: winter (November-February), spring (March- April), summer (May-

    August), and autumn (September- October). The prevalence of haemonchosis in relation to

    temperature, humidity, age and sex was also maintained. Faecal samples were examined by

    direct smear, flotation and sedimentation techniques for the presence of Haemonchus eggs

    (Muhammad F Q et al, 2009)

    The study carried out to investigate the prevalence and seasonal trend of the Haemonchus

    contortus in sheep and goats in the Potohar areas of northern Punjab, Pakistan different breeds

    were examined by the modified McMaster technique. Results revealed that the infection was

    the country. It also receives lower precipitations. Nyagatare district is divided into 14 sectors

    (imirenge): Gatunda, Kiyombe, Karama, Karangazi, Katabagemu, Matimba, Mimuli, Mukama,

    Musheli, Nyagatare, Rukomo, Rwempasha, Rwimiyaga and Tabagwe. The District of Nyagatare is

    characterized, in general, by lowly inclined hills separated by dry allies for a long period of the year

    (June-October). The District is located in the granite low valley whose altitude is 1513, 5m.

    District is characterized by two main seasons: one long dry season that varies between 3 and 5

    months with an annual average temperature varying between 25,3C to 27,7C. The monthly

    distribution of the rains varies from one year to another. Annual rain falls are both very weak

    (827 mm/an) and very unpredictable to satisfy the needs in agriculture and livestock. The river is the

    main water reserve for the people and the cattle in the large dry land. There is no other consistent

    river that can be exploited by the population in Nyagatare. The District of Nyagatare contains half ofAkagera National Park where a vast number of Wild life is found including buffalo, Antelopes and

    more other ruminants. The District also accommodates a huge variety of birds such as birds of prey,

    guinea-fowl, partridges, heroes and so forth. The hares, Wild boars, monkeys and more other small

    beasts of the rodent family are rarely found in the wooden savanna and in the natural vegetation.

    There, in the River Umuvumba, you will find Hippopotamus.

    3.3. Target population

    3.3.1 Sampling techniques

    During collection of the fecal sample for studying, and basing on population of animals (sheep and

    Goats) found in Nyagatare Sector, and then to calculate sample size the formula of Yamane (1967)

    will be used with the confidence level of 90% as follows:

    Description:

    n=Sample size

    N=Population size

    e=the level of precision corresponding in 10%

    3.3.2 Sample size

    According to formula and basing also to the population size found in Nyagatare sector of 1658 sheep and

    goats, a sample size will be considered by taking of 94 both sheep and goats conveniently.

    According to age for Goats and Sheep fewer than 10 months will be considered as young.

    3.4 Data collection

    The following materials will be used in the study

    Beakers (250ml), a tea stainer measuring, cylinder or other container graded by volume, fork, a stand,

    test tube, microscope, slides and cover slips, balance and teaspoon, flotation fluid (40g of salt in

    100ml of distilled water), formalin solution, laboratory coat, Pasteur pipettes.

    Fecal samples will be collected directly from the rectum of the animal using gloves; about 15g of

    faeces will be collected and put in a container then each sample will be labeled according to species,

    age, and sexes and then the samples will be transported to laboratory for analysis and kept in a

    refrigerate.

    3.5 Samples analysis

    When the samples will be transported to laboratory for analysis, the technique for separating

    known as qualitative technique will be used. In qualitative, simple test tube flotation method will be

    used.

    Qualitative technique using simple test tube flotation method

    This method is a qualitative test for the detection of nematode eggs in the feces. After that the

    samples will be arrived in the laboratory, approximately 5g of faeces well weighted for every sample

    will be putted into container1, 20ml flotation fluid will poured into container1, and the faeces will be

    mixed with flotation fluid thoroughly with a fork, then the resulting faecal suspension will poured

    through a tea strainer into container2. And the faecal suspension will be poured into a test tube from

    container2; the test tube will be placed in a stand, and gently top up the test tube with the suspension,

    leaving a convex meniscus at the top of the tube and carefully a cover slip will placed on top of the

    test tube; the test tube will be standed for 20 minutes, then carefully the coverslip will be left off

    from the tube, together with the drop of fluid adhering to it, and immediately the coverslip will be

    placed on a microscope slide. Then after the eggs will be observed forhaemonchus contortus on a

    microscope and the result will be recorded according to animals species, age and sexes with

    numbering of Haemonchus eggs for every focusing.The later will be helping in determination of the

    level of infestation by haemonchus after categorize each animal according to heavy, moderate and

    light stages.

    3.6 Data analysis

    The results will be analysed by using GenStat discovery 12 th edition program and Microsoft

    Excel. The average number of eggs per animal will be calculated and comparison analyzed using

    analysis of variance (ANOVA).

    3.7 Limitation of the study

    This research proposal will be carried out to determine the prevalence ofHaemonchus contortus in

    sheep and goats. It will be limited by lacking of some equipment and information facilities,

    some farmers will be refusing to assess to their animals and some of the parts of the

    study will be left untouched due to time and transporting facilities.
