6. 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.
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).
* In the profile Lysine is always the reference amino acid, and is shown at 100%.
