Effects of Dietary Different Lipid Sources on Serum Cholesterol Concentration, Fat Composition and Growth Performance in Ducks

Abstract

This research aims to determine the effects of various dietary fats on blood cholesterol, fat composition and the growth of male Bali ducks (Anas sp). The experiment used a completely randomized design (CRD) with four treatments and ten replicates of five duck per pen. The experimental diets were supplemented by using 0% oil (T0), 3% palm oil (T1), 3% palm oil that is used repeatedly (T2), 3% pork oil (T3) and 3% fish oil (T4), respectively. At the end of the treatment, body weight, feed consumption and feed conversion were recorded. Total cholesterol and fat composition were determined. The results showed that supplementation of different sources of fat significantly affected the total cholesterol, fat composition, and growth performance. Ducks received control feed (without oil) and feed with fish oil supplementation produced lower blood cholesterol and lower fat composition than palm oil and pork oil supplementation. The supplementation of fish oil and pork oil caused significantly increased growth performance. However, fish oil and pork oil supplementation produce higher cholesterol in blood serum than those other treatments. It is concluded that dietary different lipid source altered the blood lipid profile, and growth performance in duck
