| 摘 要： | 采用单因素试验设计，将30头健康的荷斯坦奶牛随机分为3组，水稻秸整株青贮分别以0、25％、50％（干物质基础）3个比例添加饲喂奶牛60d（预试验15d，正式试验45d）探讨水稻秸整株青贮对奶牛生产性能的影响。结果表明，水稻秸整株青贮可以代替一定比例的玉米青贮，并且对奶牛生产性能的影响差异不显著（P〉0．05）。同时水稻秸青贮添加量为25％（II组）和50％（Ⅲ组）的试验组每天每头奶牛的生产成本比玉米青贮的（I组）组生产成本降低了1．92元（人民币）和3．82元（人民币），相对应的收入每天每头牛增加了3．48元（人民币）和4．56元（人民币）。

| Abstract: | A single factorial was designed to study that the effects of 0, 25% and 50% of the corn silage （CS） re- placed with WRS in the forage component of the diet on production performance of dairy cow. Thirty lactating Hol- stein dairy cows were randomly assigned to three different levels of silage source diets for 60 days. Results indicated that corn silage in the diet could be partially substituted by WRS silage without adversely affecting milk production and composition for medium producing dairy cattle（P〉0.05）. However, because of the lower cost of WRS, the substitution of 25% or 50% of WRS for CS in the diet of dairy cow will save 3.48 Yuan and 4.56 Yuan per capita evereyday, respectively. |
