Cobb700 Broiler Performance & Nutrition Supplement

Introduction

This supplement presents broiler performance and yield targets for your Cobb700 broilers, together with recommendations on nutritional specifications designed to help achieve these targets. Broiler performance varies from country to country; these targets are based on a combination of field performance results and experience from around the world. The performance data included in this supplement is a blended combination from both the Cobb Male and the CobbMX male, and actual flock performance attained may be different than the values shown in this manual due to individual male line traits. 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: Metric

Imperial

The key micronutrients in particular are well known for their effect on the development and mineralization of bone. It is essential that adequate levels of these are presented to the bird throughout their development. Supplementation of compound rations with whole or cracked whole wheat can significantly deplete levels of calcium and phosphorus. Quality and availability of raw materials may require nutrient levels to be adjusted. Formulations will need to be ‘fine tuned’ to suit your specific requirements and environment. 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.

Cobb700 Broiler Performance & Nutrition Supplement

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 liveweight at any given age.

Percent breast meat yield for birds from a single flock of males processed at 50 days.

Age • Carcass and breast meat yield increase as a function of age. • Older birds processed at the same weight will often yield more than their younger counterparts. Sex A/H A/H Difference

Age 52 49 3

Weight g (lb) 3595 (7.92) 3599 (7.93) -4

% Eviscerated Carcass 79.50 79.00 0.50

Feed • Carcass composition is affected by nutrition. • Rations of varying nutrient density will affect yield in different ways. • As protein is increased there is a corresponding increase in breast meat yield as a percent of live weight.

* Preferably Choline is added directly into the mixer rather than via a premix because of its hygroscopic nature. Vitamin and trace mineral levels may vary depending on the source and supplier. The numbers above refers to e.g. usage of inorganic minerals and a vitamin D3 source. MIU = million international units; KIU = thousand international units; g = grams; mg = milligrams Supplementary levels of trace elements should always be reviewed to ensure total levels do not exceed those set in local legislation (e.g. EU 1334/2003).
