摘　　要：试验用营养酸模鲜茎叶替代奶牛部分精料观测对其泌乳性能的饲喂效果 试验共设三个试验组和一个对照组 ,其试验组营养酸模的替代率分别为 12 .5 %、2 5 .0 %及 37.5 % ,经三期 30天的饲喂 ,其结果为试验组比对照组日均产奶量分别高出 0 .93bd,2 .2 5 ab,2 .6 7a(P <0 .0 1或P <0 .0 5 ) ,比对照组 (CK)提高2 1.3% ;平均乳脂率分别提高 0 .6 3A,0 .35 B,0 .31B(P <0 .0 1或P <0 .0 5 ) ,比CK组提高 17.3% 经济效益显著 ,适应性良好 试验证实 ,用营养酸模替代部分精料发展奶牛业是可行的、有效的 。This assay used new grown stem and leaves to substit ut e part of the extractive feed,and notise the effect of its lactation ability . This assay has divided three test groups and one control group,and the propor tion of the substitute with nutritious rumex are 12.0%,25.0% and 37.5%.Through 30 days(three stages),the results showed that the average daily milk yield of th e test groups are more than that of the contrast group by 0.93 b d,2.25 a b,2069 a( P<0.01 or P<0.05 ), A.milkfat percentage each has improved 0. 63 A,0.35 B,0.31 B( P <0.01or P <0.05 ),its economic benefit is outsta nding,and it's tasty. The assay proves that it is feasible and effective to su bstitute part of the extractive feed when we develop the cow industry ,and will do good to improve the cow lactation content, milk quanlity and taste.
