The studies on nutrient balances in crossbred cattle bulls fed chopped green sugarcane tops supplemented with some agro industrial by- products.

Fifteen adult crossbred cattle bulls, 18-22 months old (mean body weight 286.33 + 9.43) were divided into 3 groups following RBD design and were fed sugarcane tops (SCT) supplemented with some agro-industrial byproducts and concentrate feeds to determine nitrogen, Ca and P in crossbred cattle bull. For this purpose, crossbred cattle bulls were fed for 30 days ad lib SCT supplemented with Wheat bran (WB), Lentil chuni (LC) and WB + LC (50:50) in Group I, II, and III respectively. The balance values were 15.28 + 2.70, 26.85 + 4.35 and 18.00 + 3.17 for nitrogen, 11.77 + 1.34, 12.94 + 2.96 and 15.38 + 1.15 for calcium, 11.74 + 0.64, 11.26 + 1.58 and 11.69 + 0.79 for phosphorus in group I, II and III, respectively. There were no significant differences among the experimental groups in Ca and P balance values but balance of nitrogen was significantly (P < 0.05) higher in group II as compared to group I and III. It may indicated that the rumen fermentation was more appropriate in group III where animals were fed 50% lentil chuni and 50% wheat bran (supplementation of both protein and energy).
