poultry AA/minerals

excrete uric acid not urea, so they need arginine and glycine. high Ca,P. rapid growth/eggshell quality. met/cys for feathers.

wet litter

wet excrement in poultry, causes wet ground, possible feet irritation

particle size

mash nor crumble! make it particles so they dont have to work so much to eat. greater starch digestibility. 800+micron particle!

broiler key concepts

maximize edible meat with smallest amt feed. profit, bird health, environmental impact (nutrient excretion), meat quality

laying breeds

.7-.8 eggs per day. small bodies, low maitenence, high livability, begin laying @ 3m

layers diet

low CP, low dietary energy. feed mash. high Ca (3-4%). limestone!

xanthophylls

carotenoid pigments, make yellow egg yolk. alfalfa, corn, marigold

turkeys

market in 14-22w, 30-40lbs. 2.5-2.8 f/g.
