INTRODUCTION TO ANIMAL SCIENCE
INTRO
Animal-mankind relationships precede recorded history.
Domestic animals serve us in many ways, primarily for food.
oUse them for pets, entertainment, and money.
oPeople are more interested in the other benets besides food
now adays.
Ruminate animals are herbivores and can digest cellulose by bacteria
(protozoa).
oWe can digest cellulose just not e%ectively. (Digest in hind gut).
Pure bread: parents are same breed and they have documentation
that they are a pure breed.
Hunter gatherersfarmersagriculture.
oAlmost all people are dependent on agriculture for their
existence.
oThe more developed agricultural countries also have the highest
standards of living.
TRUCK FARMING
Growing vegetables, fruits, and even +owers on a commercial basis.
Energy, water, soil, and technology.
oDone on a very large scale compared to the previous type:
factory farming.
oPeople become farmers to make money.
Most factory farmed crops will go to supermarkets, while the smaller
scale will go to farmer’s markets.
ROW CROP FARMING
Commercial farming: grow crops for both human and animal
production
oWeed: plant out of place (bad).
Two major crops: corn and soybeans.
oCan obtain these crops directly or indirectly.
LIVESTOCK PRODUCTION
Cattle are in a beef feedlot because they are most likely going to get
slaughtered.
Dairy cattle go out on pastures if the dairy is smaller.
oLarger dairy cattle farms use feedlots.
Both poultry and swine are non-ruminants.
oYoung chickens for mea production: broilers.
oThe desired color for both swine and chickens is white.
They’re white because they don’t want their food to be
colored (consumers).
DEFINITIONS
