Breed
Animals of common origin having characteristics that distinguish them other groups within the same species.
Most breeds were developed to fit a set of environmental constraints
-climate, forage, supply, specific, production goals
Utility of Breeds
Cattle-British-Continental-Bos Indicus
General-Sire breed-Maternal breed-Dual Purpose breed
Ranking Breeds
Sire Breed: fast growing, muscular, late maturing, low milking
Maternal Breed: early maturing sexually, inherently fertile, moderate to heavy milking, small to moderate size
Dual Purpose breed
Why use Crossbreeding?
Heterosis (hybrid vigor): ability of offspring to out perform the average of the parents breed
Complimentary of traits: take advantage of parent’s desirable traits
Angus (Scotland)
Black, naturally polled, moderate size Excellent marbling, early compositional
maturity Excellent maternal breed, easy
fleshing, good milk production Early maturing sexually Largest number of annual registrations
in the USA Recessive gene: Red Angus
Hereford (England)
Red with white face, also white on underline, switch, etc.
Moderate size, adaptable to many environments, good disposition
Poorest marbling of the British breeds U.S. registry Assn. of Hereford and
Polled Hereford; merged in 1995 2nd Largest in annual registrations in
the U.S.
Brahman (India)
American Brahman is a cross of three Indian breeds
Both red and gray strains of Brahmans exist, both have black pigmentation, horned
Noted for heat tolerance, disease and insect resistance, and crossing ability
Poor marbling ability, and slow sexual maturity
Brahman composites: Brangus, Santa Gertrudis, Beefmaster, Braford, Simbrah, etc.
Brangus (United States)
5/8 Angus and 3/8 Brahman, black and naturally polled
Excellent mothering ability, early sexual maturing, heat tolerance and forage ability result from crossbreeding
Most “widespread” composite breed in the U.S.
Santa Gertrudis (United States)
5/8 Shorthorn and 3/8 Brahman, dark red, both polled and horned
Developed on the King Ranch in Kingsville by founder Robert J. Kleberg
Breed traces back to single sire Noted for maternal ability, productivity
under hot, adverse conditions
Beefmaster (United States)
Developed by Tom Lasater in the 1930’s in Texas
50% Brahman, 25% Shorthorn, 25% Hereford, composite breed
No set color pattern Developed on the 6 essentials: weight,
conformation, fertility, hardiness, disposition, and milking ability
Noted for longevity, hardiness, rapid growth, and maternal ability
Charolais (France)
White/Off White, cream coloration Extremely fast growing, muscular
breed Large framed with relatively heavy
birth weights and large mature size Produce lean, muscular carcasses Below average maternally, problems
with dystocia
Chianina (Italy)
White coat with black skin pigmentation One of the world’s oldest breeds Extremely large framed, late maturing
that is fast growing Tremendous impact on the “show steer”
industry Produce lean, muscular carcasses,
marbling in suspect, “out of the box” Not considered a maternal breed
Limousin (France)
Reddish gold in color Moderate size Below average maternally, lack in milk
production Produce extremely lean, muscular
carcasses Fastest growing breed in the country
(% increase in registrations) 3rd in annual U.S. registrations
Texas Longhorn (Texas, were of Spain Origin)
Long, distinctive horns Lived as feral cattle for approx. 300 years from 1550-
1850, then we began to drive cattle north for slaughter (ex. Lonesome Dove
In the 1800s, began to improve Longhorns with British bulls, by the early 1900s the Longhorn was diluted nearly to extinction
1927: Dept. of Interior paid $3000 to buy a purebred Longhorns to be maintained in Oklahoma.
Maintained as a hobby breed Light muscled breed, low birth weight, excellent
hardiness and known for longevity and ability to utilize forage
Holstein-Friesian (Netherlands)
Dominant breed of dairy cattle (over 90% of all commercial dairy cattle)
Black and white color pattern (red and white do exist), large frame, easy going nature
Unparalleled milk production ability (20,121 lbs. of milk average in 305 days)
Lowest percentage in butterfat. Butterfat: solids that are used for cheese,
butter, and non-fat dry milk
Jersey (Isle of Jersey)
Small, refined animal as surpassed femininity (big brown eyes)
Light tan to dark brown shades. Highest percentage of butterfat Many herd in Texas (Bluebell) Very heat tolerant than other dairy
breeds, thus popular in the south Very fertile and early maturing sexually
Landrace (Denmark)
White in color with huge drooping ears Most prolific swine breed that is longer
than other breeds because of an extra vertebrae
More confinement adaptable than many other breeds
Yorkshire (England)
“Mother breed”, white erect ears, large and white
Noted for large litters, relatively lean carcasses and good feed conversion
Duroc (USA)
Reddish brown (range from light red to dark red) with drooping ears

Tends to be fatter than Hampshire sired pigs
Hampshire (USA)
Black with a white belt around shoulders, erect ears
Known for lean, muscular carcasses, primarily a sire breed
Pietrain (Belgium)
Black and white spotted with erect ears Extreme muscularity and leanness Normally stress positive Terminal sire breed
Merino (Spain)
Most dominant breed in the world wide sheep industry
Very fine fleeces Merinos are typically smaller than
other wool breeds and slower growing Very hardy, long lived sheep with
excellent flocking instinct White face breed
Rambouillet (France)

Louis XVI purchased 366 Spanish Merinos from the King of Spain and developed the Rambouillet at the King’s estate in Rambouillet, France
Dominant range ewe in Western U.S and Texas
White faced breed that is not extremely prolific under range conditions
Columbia (USA)
Developed at the U.S. Sheep Experiment Station in Dubios, Idaho
Crossbred of Lincoln rams and Rambouillet ewes

16#’s of wool/year) Lambs are faster growing than Rambouillets &
Merinos White faced, polled

Horned and polled strains Known for ability to breed out of
season, very prolific, and high milking ability

Medium to small sized with light brown face and legs
Farm flock breed used to produce meat Low maintenance breed with average
prolificacy and milk production

Free of wool on the head and legs (black)
Alert, active sheep that grow fast with lean carcasses
Ewes are prolific and heavy milking but produce very poor fleeces
Angora (Turkey)
Produces mohair, a luxurious fiber that commands a higher price than wool
Sheared twice a year Over 90% of the nations Angora goats
reside in Texas, primarily in the Edward’s Plateau
Finest hair ( the world’s most valuable) is produced by the kid goats with the hair getting coarser as the goat gets older
South African Boer Goat (South Africa)
Hardy, fast growing meat-type goat Medium size with prominent horns and
broad drooping ears Good meat type confirmation with
superior spring of rib, body length, and muscling
Spanish Goat (Spain)
Term Spanish goat is used in the U.S. to refer to goats of mixed breed origin
Kept largely for meat production Very prolific and hardy, utilize a great
deal of browse, thus used to clear brush and clean up re-growth in cleared areas
Nubian (Africa)
Most popular registered dairy breed in the U.S.
Noted for high butterfat Long drooping ears and “Roman Nose”

Sire line in broiler production Large, fast growing chickens that are
marginal egg producers Broad breasted, heavily muscled Tougher meat and stronger connective
tissue
Broad Breasted White Turkey (USA)
Birds are so heavy and muscular they are no longer capable of natural reproduction, also have problems with leg structure
