1 Introduction to Animal Science

2 Competency 1.00 Investigate agriculture animals in order to build a foundational knowledge for advanced animal science studies

3 Adapting animal behavior to fit the needs of people.
ANIMAL DOMESTICATION Adapting animal behavior to fit the needs of people.

4 REASONS FOR DOMESTICATION
To ensure a steadier supply of food and clothing Companionship Assist in labor

5 RESULTS OF DOMESTICATION
Less dependence on hunting and wild plants for food A surer source of food and clothing A more settled way of life Selective breeding

6 WHAT IS SELECTIVE BREEDING?
Selecting animals with certain desirable characteristics to use for breeding purposes

7 ORIGIN OF CATTLE Bos taurus- European cattle
Bos indicus- Humped cattle from tropical countries. India First brought to the U.S. by Columbus

8 Cattle Bos taurus Bos indicus

9 ORIGIN OF CATTLE Major growth of large herds in great plains states because of grazing. Midwest and north central states became the main area for finishing cattle because of grain.

10 US Cattle Finishing Grazing

11 ORIGIN OF SWINE Sus scrofa and Sus vittatus.
Chinese were first to tame pigs Brought to new world by Columbus DeSoto took hogs westward Midwestern cornbelt states became largest hog producing area

12 Swine Sus scrofa Sus vittatus

13 ORIGIN OF SHEEP One of the first animals tamed by humans
Brought to new world by Columbus Used by colonists mainly for wool Northeast and Western states are main sheep producing areas

14 Sheep 4000 BC

15 ORIGIN OF GOATS Pasang and Grecian Ibex- Wild goats found in Asia Minor Goats brought to new world for milk and hair

16 Goats Western Asia

17 ORIGIN OF HORSES Evolved from Eohippus First tamed in Asia or Persia
Brought to new world by Columbus Horses were left behind by explorers Brought to new world for work animals

18 Horses Asia and Persia

19 ORIGIN OF POULTRY Gallus gallus- Wild jungle fowl, ancestor of tame chickens Turkeys were probably tamed by people originally living in America

20 Poultry Egypt India and China North America

67 Berkshire

68 Spotted Swine Popular with farmers and commercial swine producers for their ability to transmit their fast-gaining, feed efficient, meat qualities to their offspring

69 Spotted Swine

70 Assignment Read pages 239 to 268 in the Livestock and Companion Animals textbook Answer the following questions and turn in on notebook paper:

71 Assignment (p ) What is a new breed of pig that looks like the Hereford Cattle Breed? Explain what a hybrid hog is. What is the current consumer trend in swine type? How many piglets are produced on average at each birth? How do you accurately measure backfat?

72 Total Confinement

73

74 Farrowing Crate

75

76 Identifying Breeds of Poultry

77 Breeds, Varieties, Types & Classes
Breed- group of related fowl that breed true for a specific trait Type- purpose for which it is breed (meat or egg type) Classes- geographic origin (Mediterranean, American, English and Asiatic)

78 Egg Producers Layers- chickens that produce eggs
White egg producers- small in size White Leghorns- white plumage Brown egg producers- larger birds that are not as economical as Leghorns Rhode Island Reds- dark red plumage New Hampshires- red plumage Plymouth Rocks- white plumage

79 White Leghorns

80 Barred Rock

81 Rhode Island Red

82 Layer Cages

83

84 Meat Producers Chickens used for meat production are called Broilers
Birds used for meat production are usually commercial crosses Example: White Plymouth Rock females mated to Cornish (English class) males

85 Confinement Broiler House

86 Confinement Broiler House

87 Turkeys Broad Breasted White White plumage
Shanks, feet, and beak is white to pink White pinfeathers Increases the value of the carcass Can survive better in hotter climates Good body confirmation but smaller than other breeds

88 Broad Breasted White

89 Turkeys Broad Breasted Bronze Black plumage Dark colored pinfeathers
Largest of the turkey varieties Poor fertility and reproductive problems Males are not good breeders

90 Broad Breasted Bronze

91 Turkeys Beltsville Small Whites Developed by the USDA
Similar to the Broad Breasted Whites Averages about 10 lbs. less in mature body weight

92 Beltsville Small Whites

93 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

124

125 Swine

126 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

127

128 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

129 Poultry

130

131

132 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

133 Trends in NC Poultry Recent health concerns has increased the consumption of poultry products less fat subcutaneous fat layer

134 Animal Agriculture North Carolina livestock commodities brings in twice as much money as other agriculture products

135 Livestock, Dairy and Poultry Cash Receipts from Farm Marketing, 2001

136 Cleveland County Livestock Rank Within State, (2002 estimates)
Hogs- 61st (1,500) (4,100 in 2004) Cattle- 7th (23,500) Beef Cattle 6th Milk Cattle 23rd (800) Broilers- 23rd (7,200,000) All chickens- 30th
