Effect of partial repacement of concentrate with urea-mlasses-mineral lick in growing animal ration on growth and economics of feeding
G. P. Singh, M. Mohini, B. N. Gupta
Fifteen Karan-Swiss male calves of 9-12 months of age were divided into three groups of five each in a randomized block design. Animals in group I were fed wheat straw ad lib. And concentrate mixture according to their requirements, while in group II and III the animals were fed with 1/3 of the required concentrate mixture replaced by UMM licks `Ex` and `F` respectively. The DMI(kg/day as well as per 100kgb.wt.) were similar(p>0.05) among different groups of animals, however, the digestibility of DM as well as OM enhanced from 52.85 1.48 to 58.36 1.89 and 55.33 1.48 to 60.12 1.75, respectively. Growth rates of the calves were 533.8 27.25, 532.3 42.24 and 538.4 18.68 g/d in groups I, II and III (p>0.05), respectively. Body composition and N balances of the animals were not affected by supplementation of UMM licks, however, protein retention efficiency was higher in group III (82.57 2.54) though nonsignificant. Feed cost/day was reduced from Rs. 7.92(group I) to Rs. 4.62(group II) and Rs. 3.44(group III). Hence, partial replacement of concentrates by UMM licks reduced the cost of feeding of growing calves by 41.7 to 56.6% without affecting the growth performance.
