    • 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).

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.
