An experiment was conducted to study the effect of dietary supplementation of lecithin on growth performance in Large White Yorkshire piglets fed high fat diet. Thirty two weaned piglets were randomly divided into three groups allotted to the three dietary treatments, T1- control ration (NRC, 1998), T2- control ration plus 5 per cent fat and T3- T2 plus 0.5 per cent lecithin. The total dry matter intake, fortnightly body weight of each individual animal were recorded. There was a significant improvement observed for pigs under supplemented group (T2 and T3) than that of control group (T1) with regards to all growth parameters studied such as total dry matter intake, total weight gain, average daily gain and feed conversion efficiency during the growing period.
