| Abstract: | In 90 days, 20 Dabieshan yellow cattles were divided into four groups, fed on diets containing no additives(controls), methyl-urea(diet1), urea phosphate(diet2) and additive premix (diet3 ), respectively. Average daily gain was 0. 55, 0. 65, 0. 57 and 0 .72kg respectively. Diet 1, 2 and 3 had higher daily gain (by 18 .2%, 3. 6% and 30.9 % ) than that of the controls. The cost of per unit gain was decreased to 22. 5 % and 22 %. Diet 2 had higher cost of per unit gain (by 8 % ) than that of controls. Higher daily gain and economic efficiency were observed in diets containing additive premix. |
