Livestock External Anatomy
Commercial Livestock
• Used in the livestock and poultry industry
• Crosses of more than one breed or strain of breeds
• Adds in genetic diversity– Livestock have more desired traits– Undesirable traits can be lessened
• Used by most producers
Objective• 1.03• Recognize the major parts of
cattle, swine and poultry
Cattle Parts

Cattle Parts
Swine Parts
Poultry Parts
External Parts• Anatomy
– The science of body structure• Modified skin:
– horns– hooves– feathers– fur– wool– hair
Selective Breeding• Only the best animals are chosen
as breeding stock:– Confirmation– Breed character– Structural soundness of feet and legs– Body capacity
Structural Soundness

Livestock Products• Work in groups of three and write
down as many animals products and by-products as you can.
• You have 10 min. to complete this task!
Livestock Products1. Food
– meat, – milk, – cheese, – eggs
2. Clothing– wool, – leather from hides
Livestock Products3. Shelter
– tents from hides 4. Power
– work in less developed countries

– horse back riding, rodeos 6. Fuel
– burn dry animal manure 7. Animals are converters

lubricants, brushes, etc.
Wool
By-Products6. Animal feeds from scrap meat and
bones and blood meal 7. Insulin
– for diabetics– from livestock pancreas
By-Products8. Heparin
– for blood clotting– from livestock lungs
9. Candles10. Fertilizer
By-Products11. Stearic acid, a component of fat,
is used to make automobile tires.12. Fatty acids are used in soaps,
detergents, insecticides, herbicides, paints, lubricants, asphalt, car polishes and waxes, shaving cream, deodorants and perfumes.
By-Products13. Bone charcoal, derived from
bones, is used to manufacture steel ball bearings
14. Small intestines of sheep are made into surgical sutures for suturing internal incisions and wounds.
By-Products15. Small intestines from pigs can
make skin replacements for humans
Trends in Animal Science
Objective• 2.02• Describe the economic importance
and trends for each major classes of livestock and poultry produced in North Carolina
Swine
Trends in NC Swine• The top agriculture commodity in
North Carolina – found mostly in the eastern 1/2 of the
state• North Carolina ranks 2nd nationally
– Iowa is 1st
Trends in NC Swine• The swine industry brings in over
1.5 billion dollars to the state• The number of swine farms is
decreasing– The size of farms is increasing
Poultry
Trends in NC Poultry• Broilers are Cleveland County’s top
agriculture commodity• Broilers are NC’s second rank
commodity• Broilers bring in over 1.3 billion
dollars in cash receipts to NC agriculture
Trends in NC Poultry• Recent health concerns has
increased the consumption of poultry products– less fat– subcutaneous fat layer
Animal Agriculture• North Carolina livestock
commodities brings in twice as much money as other agriculture products
