Document Summary
How you feed a broiler is dependent on the target market for the product. Feed as a % of total production costs (60-75% of total costs of production) 3-4 phases in production cycle ontario birds are generally marketed at 32 to 50 days of age depending on target market. ***see chart for different carcass types target products. The energy content of feed increases in the diet as birds get older. Age at slaughter will affect diet composition fed to birds. Live weight, carcass weight, meat yield, breast yield (by = 21% of liveweight) Breast yield because breast drives the cost of the carcass. Wings of the chicken also compete for value. There are sex differences in nutrient requirements: males>females. Today we are mixing sexes (used to separate them) Males are heavier than females at 38-42 days of age (when many ontario birds are marketed)
