dc.description.abstractA study was conducted to assess the influence of rendered fat in the diet of Large White Yorkshire sows on their litter performance. Thirty-two Large White Yorkshire gestating sows at late gestation (100 days of gestation) formed the experimental animals. Four groups with eight replicates each were maintained under four experimental diets, viz., Tl (standard ration - containing 18% crude protein and 3300 kcal DE/kg), T2 (standard ration + 5 per cent rendered animal fat), T3 (standard ration + lO per cent rendered animal fat) and T4 (standard ration + 15 per cent rendered animal fat) from late gestation (100 days of gestation) to weaning (56 days of lactation). There were no significant differences (P>0.05) observed between the four dietary treatments for the parameters observed such as litter size and piglet weight at birth and at weaning, average daily gain of piglets, body weight loss of sows during lacta~ion and piglet mortality. But there was a trend for reduction in lactational body weight loss of sows fed T2, T3 and T 4 experimental diets. The digestibility coefficients of nutrients such as ether extract (Pcrude fibre was found to be decreased (Pcrude protein were not affected (P>0.05) with the increasing energy density of the experimental diets. ii The cost benefit ratios showed an increasing trend in the economics of gain from the sows fed rendered animal fat added gestation and lactation diets than that of the control sows. The above results indicate that the rendered animal fat, as an energy source for Large White Yorkshire sows, can be added extra at 15 per cent level of the standard ration (containing 3300 kcal DE/kg and 18% crude protein) during late gestation and lactation, to improve the performance of sows and the litter and to have a better economics of gain.en_US
