Differences Between Sheep and Goats
Coat Type:
Sheep: Wool (soft and insulating)
Goats: Hair (narrow curving versus broad curling)
Tail Structure:
Sheep: Upward tail that is often docked.
Goats: Tail hangs down.
Upper Lip Structure:
Sheep: Continuous upper lip.
Goats: Separate lobes.
History of Domestication
Sheep:
Species: Ovis aries.
Domestication Date: Approximately 9,000 BC.
Origin: Derived from Mouflon in Eurasia.
Goats:
Species: Capra hircus.
Domestication Date: Approximately 8,000 BC.
Origin: Originates from wild goats in Eurasia and the Middle East.
Reasons for Domestication:
Size, sociability (gregarious), ability to utilize diverse feed resources, and production of various products (meat, milk, leather, fiber).
Sheep Industry Data
Population Data (as of 2022):
Total Sheep and Lambs: 5.02 million.
Number of Sheep Operations: 79,500 (as of 2019).
Per Capita Consumption (US vs. World):
US: 0.88 lb
World Average: 3.97 lb
Australia: 12.79 lb
Kazakhstan: 19.18 lb

Major Importers and Exporters of Sheep Products
Major Importers: France, United Kingdom, China, United States.
Major Exporters: New Zealand, Australia.
World's Main Producers: China, Australia, India, Nigeria, Iran.
Types of Sheep Operations
Purebred (Seedstock Producers): Used for breeding commercial stock or showing lambs.
Commercial Operations: Focused on lamb/meat production, with wool as a secondary source of income.
Dairy Operations: Focus on cheese production with an emerging industry in the Great Lakes region.
Classification of Sheep Breeds
Thin Wool Breeds:
Micron Range: 17-20 microns.
Offspring: 2-3 lambs.
Examples: Rambouillet, Merino.
Meat Breeds:
Characteristics: Good carcass quality and growth rates.
Offspring: 1-2 lambs.
Examples: Hampshire, Southdown.
Dual Purpose Breeds:
Characteristics: Medium size (200-300 lbs), adequate wool and meat production.
Examples: Columbia, Dorset.
Long Wool Breeds:
Characteristics: Coarse wool with good hardiness.
Examples: Lincoln, Romney, Scottish Blackface.
Hair Breeds:
Adaptations for hot, humid climates with good resistance to diseases.
Examples: Katahdin, Dorper.
Production Systems in Sheep Farming
Types of Operations:
Stock Sheep Production Operations.
Farm Flocks: Generally smaller farms.
Range Flocks: Operate in extensive pastoral lands.
Lamb Feeding Operations: Specialized in feeding lambs for market.
Sheep Feeding Practices
Ewes:
Diet: Pasture or roughage supplemented with grain.
Flushing: Increase feed during breeding to enhance lamb birth rates.
Rams:
Diet: Sufficient pasture, supplemented with grain during breeding.
Lambs:
Feed: Milk until weaning; common to creep feed.
Post-Weaning: High amounts of grain until market weight.
Copper Sensitivity: Sheep are very sensitive to copper toxicity.
Reproductive Practices in Sheep
Breeding Cycle:
Seasonal breeders (breed in fall, lamb in spring).
Puberty can occur as early as 6 months, but breeding typically occurs at 60% of adult weight.
Breeding Ratio: 1 ram per 15-35 ewes for younger rams; up to 50 for older rams.
Health Maintenance:
Clean and provide adequate nutrition to avoid diseases.
Internal parasites pose significant risk, especially in southern regions.
Tail Docking: Reduces manure build-up and maggot proliferation.
Sheep Health Management
Key Challenges:
Haemonchus contortus (internal parasite).
FAMACHAO System:
Clinical categories based on eye lid color and packed cell volume (PCV):
1 (Red): ≥ 28 PCV - No treatment required.
2 (Red-Pink): 23-27 PCV - No treatment required.
3 (Pink): 18-22 PCV - Treatment advised.
4 (Pink-White): 13-17 PCV - Treatment required.
5 (White): <12 PCV - Treatment required.
Infrastructure and Equipment in Sheep Farming
Housing Requirements:
Adequate shelter from severe weather.
Design of pens to facilitate handling of sheep.
Predator Control Methods:
Use of fencing and guard animals (dogs, llamas, donkeys).
Implementation of trapping and hunting strategies.
Sheep Shearing
Shearing Requirements:
Annual shearing is necessary for wool production.
Hair sheep do not require shearing.
Products Derived from Sheep
Wool:
Characteristics measured in microns (MU), crimps per inch (C.P.I.), and clean wool yield percentage after processing.
Meat Products:
Lamb: Meat from young sheep; generally more tender.
Mutton: Meat from older sheep; tends to be tougher.
Seasonal demand peaks during holidays and celebrations.
Primal cuts include shoulder, breast, rib, leg, loin, flank, shank, and neck.
Challenges in Sheep Production
Wool Industry Challenges:
Competition with synthetic fibers.
Issues related to isolation of range flock production.
Threats from predator attacks.
Goat Industry Overview
Population Data:
Total Goats: 2.58 million.
Number of Goat Operations: 149,000.
Products from Goats:
Meat: Known as "chevon" or "cabrito", a growing industry in the U.S.
Milk: Primarily used for cheese, especially beneficial for individuals with cow milk intolerance.
Fiber: Cashmere and mohair derived from Angora goats.
Classification of Goat Breeds
Dairy Breeds:
Characterized by stylized, angular bodies.
Selected for udder health and milk production.
Examples: Saanen, Nubian, Alpine.
Meat Breeds:
Characteristics include smaller size and greater muscle conformation.
Examples: Kiko, Boer.
Fiber Breeds:
Cashmere and Angora goats are specifically cultivated for fiber production.
Goat Production Practices
Production Growth:
Current meat production in the U.S. does not meet demand.
Goat cheese gaining popularity among consumers.
Feeding Preferences:
Goats prefer browse over pasture but will eat grass when necessary.
Generally, goats are smaller and more resilient than sheep.
Specialized Practices in Goat Farming
Contract Grazing:
Goats can be utilized for contract grazing in various settings.
