摘要
奶牛日粮中添加海带粉的试验组 ,与不添加的对照组 ,两组奶牛日均产乳量分别为 18.5 5± 1.12kg,17.14± 1.16kg,两组差异显著 (P <0 .0 5 ) ;乳脂率分别为 3.5 1% ,3.5 2 % ,两组差异不显著 (P >0 .0 5 ) ;奶料比分别为 2 .32∶1,2 .14∶1,两组差异显著 (P <0 .0 5 ) ;试验组比对照组提高经济效益 10 .9%。
The average daily milk production capacities of the trial group fed on diet with kelp meal and the control group were 18.55+1.12 kg and 17.14+1.16 kg respectively. The differences between two groups were remarkable (P<0.05). The rates of milk and fat were 3.51% and 3.52% respectively, the differences were not remarkable(P>0.05).The rates of feed and milk were 2.32:1 and 2.14:1, the differences were great(P<0.05). So the economic benefit of the trial group was increased by 10.9% comparing with the control group.
