Domestication
  • After animals become domesticated, they become
    dependent on man
  • Most cant survive in wild
  • Most poultry cant fly
  • Sheep dont shed wool
  • Cows produce 20,000 lbs milk / year
  • Birds produce 250 eggs / yr. (20 in wild)

4
Animal Use as Food
  • Meat - (muscle tissue) Beef, Pork, Lamb, Goat,
    Poultry
  • Milk - inexpensive source of protein
  • cheese, ice cream, yogurt
  • Eggs - pastries, mayonnaise, custards

5
Animal By-Products
  • Bones - buttons, glue, mineral supplement for

  • Hides - leather
  • Hair - wool, mohair, fiber
