Cobb700 BroilerPerformance & Nutrition Supplement
Performance & Nutrition Supplement
www.cobb-vantress.com
This supplement presents broiler performance and yield targets for your Cobb700 broilers, together with recommendations on nutritional specifications designed to help achieve these targets.
The performance objectives in this supplement are displayed in both imperial and metric 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. (Available at: https://www.cobb-vantress.com/resource/managementguides)
Today’s broiler farmers not only want to raise broilers that grow efficiently, but also want broilers that have good livability and good animal welfare characteristics. Cobb’s dedication for broiler genetics has generated incredible advances in economic traits related to feed efficiency, growth and muscle quality, and has also produced broiler genetics with improved cardiovascular function, better skeletal strength, and more uniform body size.

Vitamin and trace minerals may vary depending on the source and supplier.The numbers above refer to e.g. usage of inorganic minerals and vitamin D3 source.Supplementary levels of trace minerals should always be reviewed to ensure total levels. Do not exceed those set in local legislation.KIU = Thousand international unitsg = grams
* All finisher feeds.** Preferably choline is added directly into the mixer rather than via a premix because of its hygroscopic nature.

Amino Acid
* Should withdrawal feed be required, use same finisher specification.** In the profile, Lysine is always the reference amino acid shown at 100%.
Yield Performance
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 live weight at any given age.
Age
Carcass and breast meat yield increase as a function of age.
Older birds processed at the same weight as their younger counterparts will often yield more.
Feed, Yield, and Economics
Carcass composition is affected by nutrition.
Rations of varying nutrient density will affect yield in different ways.
The exact overall levels of amino acids should be determined by ingredient prices and finished product values (from the processing plant).
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.

COBB700 PREDICTED YIELDS
All yield values are dry yield (before chiller) based on percentage of live weight.
Carcass refers to the eviscerated bird with feet removed at the hock joint.
Boneless breast meat is calculated without skin and bone.
Thigh, drumstick and wing are calculated with skin and bone.
