 Thirty weaned female Large White Yorkshire piglets were divided in to three groups with five replicates in each group and were maintained under identical management conditions for the period of 70 days. The three dietary treatments were randomly allotted, T1-control ration as per NRC (1998), T2 -50 per cent of maize of control ration replaced by animal fat and T3-100 per cent of maize of control ration replaced by animal fat. The average daily gain and feed conversion efficiency were 813.00, 769.86, 678.43g and 2.80, 2.88, 3.08, respectively for three dietary treatments. The pigs of T1 had higher (P<0.05) average body weight gain than that of other treatments. The crude fibre digestibility was higher (P<0.05) for T1 and T2 rations than that of T3. The digestibility of dry matter, organic matter, crude protein and NFE was higher forT1 ration than the other groups. Availability of calcium, magnesium and manganese was lowered (P<0.01) in T3 group. It can be concluded that partial (50 per cent) replacement of the maize in the feed for pigs by animal fat did not affect the weight gain, feed intake, feed conversion efficiency and nutrient utilization.
