EFFECT OF NICOTINIC ACID ON PLASMA AND BODY PROTEINS AND LIPIDS IN BROILERS

Numerous attempts were made to reduce carcass fat in broilers by genetic, nutritional and pharmacological manipulation in the past years, so as to reduce the incidence of coronary heart disease in consumers of broiler meat. In this study an attempt was made to reduce carcass fat and increase carcass protein by using nicotinic acid as the pharmacological agent. The result of this study revealed that nicotinic acid at 200 mg and 400 mg produced a significant increase in cumulative weight gain and improved feed efficiency. Nicotinic acid at both doses reduced plasma triglycide at 6th week. But at both doses the drug reduced plasma cholesterol significantly, increased carcass protein and decreased carcass fat percentage.
