Dr. Dipa Brahmbhatt VMD MPH

Chapter 14 - 1

Objectives• Zoological classification of the species.• Terminology associated with the species.• Physiological data for the species• Prominent anatomical or physiological properties of the species.• ID and describe characteristics of common breeds. • ID and know the uses of common instruments relevant to the

species. • Normal living environments and husbandry needs of the species.• reproductive practices of the species.• Specific nutritional requirements of the species.

Chapter 14: Ovine and Caprine Husbandry and small ruminants terminology

Zoological Classification of Sheep and Goats

• Kingdom: Animal• Phylum: Chordata• Class: Mammalia• Order : Artiodactyla• Family: Bovidae• Genus and species

– Ovis Aries– Capra Hircus

Terminology for Sheep

• Ewe: Adult female• Ram: Adult male • Wether: Castrated male• Yearling ewe: Immature female• Lamb: Neonate• Wether lamb: Castrated neonate• Ram lamb: Intact male neonate• Ewe lamb: Female lamb• Lambing: Act of parturition

Terminology for Goats

• Doe/nanny: Mature female• Buck/billy: Mature male • Wether: Castrated male • Yearling doe: Immature female• Kid: Neonate• Buck kid: Male less than one year • Doe kid: Female less than one year• Kidding: Act of parturition

Sheep and Goats: Both family Bovidae

• Sheep – Ovis aries– Tail down– Grazers close to soil

(short tender grasses and clovers)

– Distant and aloof– Distinct philtrum– Curved horns

• Goats – Capra Hircus– Tail up (unless sick)– Natural browsers on top

of plants (twigs, vine, shrubs)

– Curious and independent

– Distinct odor as they mature

– Straight horns

Sheep & Goat Overview• Originated: Europe and cooler regions on Asia.• Important in temperate and tropical agriculture.• Provide fibers, milk, meat, and hides.

– Sheep• Milk: more nutritious• Cheese: Feta (Greece, Italy, and France), Ricotta and Pecorino Romano (Italy) and Roquefort (France)• Fiber and meat

– Goat: milk, meat, fiber

• Versatile and efficient: developing countries.

Sheep & Goat Overview

Sheep – declined in the U.S. (less than 0.2% of total farm revenue in U.S.). Mostly import. Avg: 50/ farm– Less demand for wool.– Declining demand for lamb in consumer diets.– Difficulty in obtaining/keeping reliable herders– Competition for public-owned rangeland.– Predators ~ 23% lost before maturity

Anatomical Terms for Sheep

Anatomical Terms for Goats

Sheep breeds

• Fine wool breeds: FWB– Merino, Rambouillet

• Medium wool breeds: MWB– Cheviot, Corriedale, Dorset, Finnish Sheep,

Hampshire, Montadale, Oxford, Polypay, Romanov, Shropshire, Southdown, Suffolk

Corriedale (cont’d)

Royal White• hair breed, privately funded

in Hermleigh, Texas (heat resistant)

• longer hair coat in the fall - shed spring.

• pure white. • Ewes and rams are polled• Scrapie resistant?

production• Medium size: good

conformation• Polled• Medium ears carried erect• Light brown face and legs

with wool on head and legs• Adapted to wet conditions

LaMancha

Major Breeds GoatsAngora (Asia Minor) or Mohair

From Angora, Turkey Both sexes are horned: they are some that are polled

Pronounced spiral to the horn Utilized in Mohair Production (Mohair is a silky textile produced from the hair of the

angora goat). White in color

Fiber: kid fleece is more valuable. 6-7 lb / year/ head to fiber

Goat Breeds and SelectionAngora Goat Selection

In selecting for fiber, one is interested in both

quantity (weight) and quality of fiber (length,

fineness, style, character, etc.).

In addition to fiber, one must be concerned

with traits that contribute to the survival or

viability (soundness, fertility, etc.) of the

individual.

Angora

Major Breeds GoatsBoer (South Africa)

Also known as the Africander Early maturing

White color with red head and white blaze: breed standards Fertile

Usually horned Large

Fertility high: kidding rate 200% so 3 kiddings every 2 years

Boer

Major Breeds of GoatsSpanish (Spain)

Feral goat/ brush goat/ meat goat native to U.S.

Long horns, all colors accepted Descended from the goats that

were released or escaped from the early Spanish explorers

Utilized for meat and milk Fat content is less than beef Prolific: survive with little care:

popular in TX

Spanish

Major Breeds GoatsNigerian Dwarf (West Africa)
