Abstract

An experiment was conducted to study the effect of different levels of energy in the diet of Large White Yorkshire pigs on energy utilization. Twenty weaned female Large White Yorkshire piglets were randomly divided into two groups and allotted to the two dietary treatments, T1-control ration: as per NRC, 2012 and T2-high energy ration: control ration + 400 kcal/kg of ME and maintained for 70 days. Digestibility trial was conducted following total collection method and gross energy was estimated using bomb calorimeter. Gross energy of feed and faeces were 4173.92, 4410.07 and 3834.24, 4090.08 kcal/kg, respectively for T1 and T2 treatments. The gross energy converted as digestible energy was 74.37 and 87.27 per cent and the calculated digestible energy of feed was 3104.22 and 3848.81 kcal/kg, respectively for two treatments. This study reveals that higher energy content of diet over and above the requirement of pigs increased the efficiency of energy utilization in growing Large White Yorkshire pigs.
