摘要
试验选用了12头奶牛,根据产奶量、泌乳天数和胎次相近的原则分为试验组和对照组,研究全混合日粮对奶牛产乳性能的影响。试验结果表明,试验组4％标准乳产量比对照组提高1 24kg,差异显著(P<0．05),乳脂率及乳脂、乳糖和乳固形物含量也分别比对照组显著提高11．60％、17．50％、13．21％和9．86％(P<0.05)。
An experiment was conducted to study the effect of total mixed ration（TMR） on milk performance in dairy cattle.Twelve cows were divided into experiment group and the control group according to milk yield,calving date and lactation.The results indicated that：the 4 % fat corrected milk （FCM）in the experiment group significantly increased by 1.24 kg compared with the control group （P 〈 0.05）;the milk fat content,milk fat yields,lactose and milk solid yields in the experiment group significantly increased by 11.60 % ,17.50 % ,13.21% and 9.86 % than that of the control group respectively（P 〈 0.05）.
