奶牛专用脲酶抑制剂复合预混料提高奶牛产奶量效果的试验

Feeding-trial Survey about the Improved Effect of Dairy Cow Special Urease Inhibitor Compound-premix on Dairy cow's Milk Output

通过32头健康泌乳奶牛进行饲喂奶牛专用脲酶抑制剂复合预混料的对比试验.结果表明,饲喂脲酶抑制剂复合预混料的试验组,泌乳奶牛平均日产标准乳22.81kg/头,对照组泌乳奶牛平均日产标准乳20.12kg/头,产奶量提高13.37%(P<0.05);校正体重后试验组比对照组提高产奶量14.41%,差异显著(P<0.05);提高饲料转化率13.43%,差异显著(P<0.05);提高经济效益13.68%,增收效益明显。

A comparative feeding trial was done by using 32 health lactating dairy cows fed with dairy cow special urease inhibitor compound-premix.The results showed that each of the lactating cows in experiment group fed with urease inhibitor compound-premix averagely produced 22.81 kg standardized milk per day, while those in the control group had an average daily standardized milk production of 20.12 kg per head. The milk output of the former was 13.37% higher than that of the latter, the difference was distinct （P 〈 0.05） and the difference increased to 14.41% after weight adjustment. Feed conversion ratio of experiment group was 13.43% higher than that of control group, the difference was distinct （P 〈 0.05）. The experiment group had 13.68% more profit than that of control group, resulting in apparent profitability.
