2. Animal Science What is Animal Science?

3. The study of the care, management and production of domestic animals Today’s animal science includes: biotechnology genetics research behavior research

4. Domestication To adapt the behavior and productivity of an animal to fit the needs of people.

5. Domestication Allowed us to select animals based on their productive traits. Most productive dairy cows The fastest growing beef cows The most feed efficient lambs Sheep that don’t shed their wool The chickens that lay the most eggs

6. Have you ever hunted a wild turkey?

8. The Wild Turkey Wild turkeys are naturally lean and muscular. They must be able to move fast to escape enemies. Wild turkeys are alert and cunning. They have to be to stay alive. Wild turkeys recognize predators. Wild turkeys protect themselves and their young.

9. Survival of the fittest…. The fastest The strongest The most observant The quickest to react

10. Behavioral Domestication The selection of the slowest and least reactive animals! Animals that could be caught! Animals that would accept confinement. Animals that would accept human interaction.

11. Your turkey dinner….

12. Domestication What was the first animal domesticated? 14,000 years ago!

15. Today’s domesticated animal… Most can not survive in wild Most poultry can not fly, But Why? Lean pigs do not have any body fat to keep them warm! Imagine the modern Dairy cow making it without proper nutritional support?

16. The Wild pig…

17. The Domesticated Pig …

18. Animal Uses Food Milk Meat Work Medicine & Research Clothing

19. Meat Production What types of animals are used for meat? Cattle Swine Lamb Horses Poultry Goat Buffalo

20. Meat Production Other significant sources of meat in other countries: Alpaca Llama Yak Deer Reindeer Fowl: duck, turkey, goose Elk Antelope Kangaroo Rabbit Guinea Pig

21. Meat Production Animals are the most efficient, enviromentally friendly users of plants. They can harvest and convert vegetation that is UNDIGESTIBLE by humans They create HIGH quality protein out of LOW quality protein plant sources 2/3 rds of the worlds agricultural land is not suitable for growing crops!  It is, however suitable for PASTURE!

22. Meat Production Meat Provides A balanced assortment of amino acids (proteins) that more closely matches the needs of the human body than that of plant based proteins. Vitamin B12 is required by the human body, and is not found in plants… only meat.

26. Milk Production Milk is the most inexpensive source of protein Cheese, ice cream, yogurt
