139
Ratites
Emus and Ostriches

Mead: federally inspected, closer to beef, lean product, normally sold ground
140
Broiler Production- industry trends
dominated in SE US (Georgia, Arkansas, Alabama)- affordability of raising, chap land, buildings, large cheep labor force
3 fold increase in consumption since 1960
Tyson #1
Vertical integration
141
Layer Production- industry trends
Iowa and Ohio, market controlled by companies w/ over 1 mill birds, ship out a lot of the dark meat
91.9 billion eggs in 2011, 345 million layers
Call-Maine #1 in egg producers
142
Turkey production- industry trends
No geographic center (Minnesota- 17%, N Carolina-15%)
14-17 wks age (15-28 lbs) market
70% of turkey is processed
143
Life of a broiler
Breeder and multiplier flocks- broiler production --> hatchery --> contract or company grow-out farms --> processing plant (further processing plants) --> marketing and distribution
Feed mills provide for breeder and multiplier flocks and hatcheries
144
Life of a layer
Hens: breeder flocks --> hatchery --> grow out (16-18 wks of age, birds more to layer facility, controlled environment, lots of light, start laying @ 20 wks) --> Egg production --> bird processing --> other food products
Eggs: egg assemble packer --> wholesale distributer --> egg products or retail
145
Production systems for poultry
Specialized collection for eggs before hatching to allow for uniform hatching time (65 degrees delay embryo development)
Broiler: elongated house that holds up to 64,000 birds, have completely automated system for food, water and meds, collection done manually during colder temps
Layers: Battery cage system, cage free, free range
146
Role of poultry industry in US economy
$35.6 bill industry direct, 12% of all agriculture, 33% of animal profits

Good things come from poultry
Nutrition, medicine, sport, research
Eggs have everything except Vit D- nutrient quantities controlled by diet
Research- vitamin discorveries, toxicology

Four categories of horses:
1) light
2) draft
3) ponties
4) miniatures
150
Quarter horse
```
light breed
typically muscular horses

152
Arabians
```
