This supplement presents broiler performance and yield targets for your
Cobb500 broilers, together with recommendations on nutritional
specifications designed to help achieve these targets.
Broiler performance varies from country to country. The growth rates shown
are the targets for achieving cost-efficient performance.
The performance objectives in this supplement are displayed in both
metric and imperial configurations:

Please contact your local Cobb technical representative to help develop a
program designed specifically to suit your own local conditions based on
the advice and information contained in this supplement and the main
Cobb Broiler Management Guide.

Meat yield is dependent on many factors, but those that have the most
influence are weight, age and nutrition.
Weight
• Carcass and breast meat yield increase as a function of liveweight at any
given age.
The graph above is a representative sample of percent breast meat yield (dry yields) for birds from
a single flock of as-hatched broilers processed at 48 days.
Feed, Yield, and Economics
•Cobb data have shown that protein and amino acids can be elevated by
approximately 8 percent for the purpose of increasing breast meat yield,
although higher feed cost per unit of live weight may be a secondary result.
•For the most economical feed per unit of live weight, lower amino acids
may be more applicable, 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 and finished product values (from the processing plant).
•The Cobb 500 is a flexiblebroiler that can bring good costs from low
amino acid density feeds, or will respond with accelerated growth and
breast yield using high amino acid levels.
•Cobb Technical Service will gladly assist customers to match specific
economic priorities with formulation; however, the recommendations in this
supplement represent very sound overall baseline levels.
