脲酶抑制剂饲喂小肥牛生产性能测试

Production Performance of Veal Calves fed by Urease Inhibitor

对利用脲酶抑制剂饲喂小肥牛的增重效果进行比较试验。结果表明 ,试验组牛头均总增重 1 40 .31 kg,日均增重 775g,平均屠宰率 53.55%,比对照组牛头均总增重 93.51 kg、日均增重 51 6g、平均屠宰率 52 .0 6%分别提高 50 %、50 %和 1 .49个百分点 ,总增重和屠宰率组间差异极显著 ( P<0 .0 1 )。试验期内试验组牛较对照组牛头均增利 32 5.8元。

Growth and fattening results of veal calves fed with urease inhibitor indicated that total average body weight gain per head of cattle in experimental group was 140 31 kg with ADG of 775 g, dressing percentage of 53 55%, which increased by 50%, 50% and 1 49 percentage point compared with corresponding data of 93 51 kg, 516 g and 52 06% in control group, the total BW gain and dressing percentage showed a significant differences between two groups (P < 0 01), the per head income of experimental group during the trial was 325 8 RMB yuan more than control group
