2. Domestication
After animals become domesticated, they become dependent on man
Most can’t survive in wild
Most poultry can’t fly
Sheep don’t shed wool
Cows produce 20,000 lbs milk / year

Assist physically & medically handicapped
Blind
Epileptic & Diabetic

6. Other Animal Use Hides - leather Hair - wool, fiber

Pets

7. What is the future of Animal Science?
Embryo Transplant - can produce 20 calves from one cow per year
Cloning - using an animal cell to grow an identical duplicate animal
