Supplementary levels of vitamins and trace elements (per tonne)

Meat yield is dependent on many factors, but those that have the most influence areweight, age and nutrition.

Weight• Carcass and breast meat yield increase as a function of live weight at any given age.

The graph above is a representative sample of percent breast meat yield (hot yields) for birds from a single flock of as-hatchedbroilers processed at 48 days.

Feed, Yield, and Economics• Cobb data has shown that protein and amino acids can be elevated by approximately8 percent for the purpose of increasing breast meat yield, although higher feed costper unit of live weight may be a secondary result.

• For the most economical feed per unit of live weight, lower amino acids may be moreapplicable, although slower growth rate and higher FCR may be a secondary result.

• The exact overall levels of amino acids should be determined by ingredient prices andfinished product values (from the processing plant).

• The Cobb500 is a flexible broiler that can bring good costs from low amino aciddensity feeds, or will respond with accelerated growth and breast yield using highamino acid levels.

• Cobb Technical Service will gladly assist customers to match specific economicpriorities with formulation; however, the recommendations in this supplement representvery sound overall baseline levels.
