Description The objective of this study was to improve the nutritive value of two percent urea treated paddy straw and Rhodes hay with supplementation of surfactant and cellulolytic enzymes on the performance of growing crossbred heifers. In the first growth trial, eighteen crossbred heifers were assigned equally into three groups of six each in a completely randomized design. The trial consisted of thirteen weeks duration. The treatment groups were fed diet as T-1: Free choice feeding of 2 per cent urea treated paddy straw, T-2: Free choice feeding of 2 per cent urea and 0.1 per cent Tween-80 treated paddy straw T-3: Free choice feeding of 2 per cent urea , 0.1 per cent Tween-80 and 0.5 per cent cellulolytic enzymes treated paddy straw. The concentrate mixture containing 97 per cent maize was uniformly offered to the animals at 0.75 per cent of body weight. The average daily gain as g/day (ADG) was not significant (P>0.05), but higher in groups T-3 (463) and T-2 (414) compared to T-1 (359). The apparent per cent digestibility of DM (66.44), OM (69.64), NDF (61.76) and Hemicellulose (78.86) was significantly (P0.05), but higher in groups T-3 (540) and T-2 (532) compared to T-1 (500). All the animals in treatment groups showed positive nitrogen balance. The results of the study indicated that the supplementation of surfactant and cellulolytic enzymes had no advantage in improving the efficiency of feed utilization. It is concluded that two percent urea treatment to paddy straw and Rhodes hay along with concentrate mixture was beneficial in obtaining satisfactory ADG of crossbred heifers, however the application of T-80 and cellulolytic enzymes could not improve nutritive value of both urea treated paddy straw and Rhodes hay.
