The dry matter contains not more than 4 percent of lipids if bypass fat is not used. It could be up to 7 percent of bypass fat is present in the ration, bypass fats include calcium soap of fatty acids, palmitic acid, canola oil, etc. In poultry ration up to 4 percent to cope up Metabolizable energy.

If fats used more than 4 percent it decreases the milk protein, feed intake, and milk composition.
