Performance of Crossbred Cattle Fed Chopped Green Sugarcane Tops and Supplemented with Wheat Bran or Lentil Chuni Concentrates

Abstract
Fifteen crossbred cattle bulls of about 22-24 months age (mean body weight ranged from 291.0 to 298.1 kg) were randomly divided into 3 groups of 5 animals following randomized block design. Animals in group 1 were fed concentrate mixture containing wheat bran 97%, mineral mixture 2% and salt 1% plus ad libitum chopped green sugarcane tops (SCT) as a roughage source. Animals in group 2 were fed concentrate mixture containing lentil chuni 97%, mineral mixture 2% and salt 1% while group 3 concentrate contained wheat bran 48.5%, lentil chuni 48.5%, mineral mixture 2% and salt 1% plus ad libitum chopped green SCT to meet their maintenance requirements. During metabolism trial period, the mean total intake and digestibility of DM in groups 1, 2 and 3 was 8.09 0.41, 8.41 0.49 and 7.86 0.16 kg/d and 60.24, 63.24 and 65.05%, respectively. The intake of CP (p<0.05) and EE (p<0.01) was significantly higher in group 2 and group 1, respectively as compared to remaining 2 groups, which were comparable. Digestibility of CP and EE was significantly (p<0.01) higher in group 3 and that of CP was comparable with group 2. The intake and digestibility of total carbohydrates, NDF, ADF, Hemi-cellulose and cellulose were similar among 3 groups. The mean body weight changes in group 1, 2 and 3 were 173.4, 253.4 and 203.4 g/d, respectively, which was significantly (p<0.05) higher in group 2. The total nitrogen (N) and phosphorus (P) intakes were significantly higher in group 2 and group 1, respectively. The total volatile fatty acids, ammonia-N, trichloro-acetic acid precipitable nitrogen (TCA ppt.-N; p<0.05), total-N concentrations and pH were significantly (p<0.01) higher in group 3, however, pH and TCA ppt.-N was comparable with group 2 and 1, respectively. From the results, it may be deduced that the feeding of chopped green SCT supplemented with a concentrate mixture having both wheat bran (48.5%) and lentil chuni (48.5%) has shown a better performance with respect to intake and digestibility of nutrients and growth as well.
