What is an important part of sheep history?
Sheep was the first food-producing animal to be domesticated in 8000 B.C., goats soon after.
22
What is range production?
Large number of sheep & large acreage.
- Migratory--located in intermountain states
----sheep attended by herders, graze on large parcels of unimproved, mountainous land
-Fenced
----primarily located in Texas, left unattended, graze of fenced acre parcels of land
23
What is farm flock production?
Occurs in midwestern & eastern states,
- commercial--primarily produce lambs for meat markets in the U.S. or for ethnic market trade
- smaller, more diverse operations with higher production costs than range operations.
24
What is purebred sheep production?
Small operations specializing in production of purebred breeding stock for commercial producers.
25
How is the structure of the goat industry different from that of the sheep industry?
No migratory range goat production; large meat goat operations located in Texas similar to fenced range production. Feedlots are not an important feature due to lighter market weights for goats. Processing plants are small & processing also occurs on farms. Caters to a primarily ethnic-based market.
26
What are the classifications of sheep breeds?
Reproduction:
Ram--generally black-faced sheep selected for growth & superior meat quality of their offspring
Ewe--generally white-faced sheep selected for reproductive efficiency, mothering ability, & fleece weight
Dual purpose--used for meat & wool production & adapted to diverse climates.
Hair sheep--hair fibered coats that do not require shearing, with superior fertility, parasite resistance & adapted to hot climates
Dairy--used for milk production but not very prominent in the United States
27
What is the classification for goat breeds?
Dairy--used for milk production
Meat--used for meat production
Dual purpose--used for meat & milk production
Fiber--used for fiber production

28
What are the types of identification?
Paint branding
Ear tagging
Tattooing
29
How are goats disbudded, and what are some pros & cons?
Goats are disbudded by holding a hot iron around the horn buds to burn them off. If held too long, brain damage can occur. If not held on long enough, scurs can form.
Pros:
- safety for others in a herd, for people working with goats/sheep
Cons:
- goat horns help regulate body temperature
-protection from predators
