摘要
介绍了用 16头健康泌乳奶牛进行饲喂脲酶抑制剂预混料的对比试验。结果表明 ,饲喂脲酶抑制剂预混料的试验组 ,泌乳奶牛平均日产标准乳 18.18kg/头 ;未添加饲喂的对照组 ,泌乳奶牛平均日产标准乳 16 .84kg/头。前者比后者提高产奶量 7.96 % ,差异显著 (P <0 .0 5 )。试验期间 ,试验组比对照组增加盈利 1.15元 /d,增收效益明显。
A comparative feeding trial was done by using 16 healthy lactating cows fed with urase inhibitor premix. The results showed that each of the cows in experiment group fed with urase inhibitor premix averagely produced 18.18 kg standardized milk per day; while those in the control group which were not fed with urase inhibitor premix had an average daily milk production of 16.84 kg/head. The milk output of the former was 7.96% higher than that of the latter, the difference was distinct ( P <0.05). During the feeding trial the experiment group had a profit increase of 1.15 RMB Yuan higher than that of the control group every day, resulting in apparent profitability.
