EFFECT OF CITRIC ACID SUPPLEMENTATION ON GROWTH AND NUTRIENT UTILIZATION IN THE DIET OF CROSSBRED PIGS

摘要

In a completely randomized design, 24 crossbred (LWY X Desi) male pigs (16.4 +/- 0.25 kg) were divided at random into 4 equal groups to study the effect of supplementing(%) citric acid at 0.6 (T-1),0.9 (T-2) and 1.2 (T-3) and 0 (T-4) to the grower (15-35 kg) ration on nutrient digestibility, nitrogen balance and growth performance. The digestibility of DM, CF', NFE and N retention were higher (P<0.01) in T-2 as compared to other groups. The ADG and the efficiency of feed utilization was also higher in (P<0.05) in T-2 in comparison to others. It was concluded that citric acid supplementation at 0.9% in the diet was beneficial in improving the nutrient digestibility and daily gain of crossbred pigsC1 [Suryanarayana, M. V. A.
