摘  要：
选取年龄、体重相近和首次产犊且处于泌乳后期(200d)的西门塔尔牛60头,采用完全随机区组设计分为6组,对照组饲喂由青贮玉米、苜蓿草粉、小麦秸和精料组成的基础日粮,试验组日粮中分别以5kg、10kg、15kg、20kg、25kg的青贮苹果渣替代等量青贮玉米。结果表明,以青贮苹果渣替代青贮玉米对西门塔尔牛的产奶量和乳品质均有一定程度的提高,替代50%时可显著提高牛的产奶量、乳脂率和乳蛋白含量(P<0.05),但对乳糖和非脂固形物含量没有明显影响(P>0.05)。试验表明,青贮苹果渣替代一定比例的青贮玉米对西门塔尔牛的产奶量、牛奶品质有改善作用。

摘  要：
Selected 60 simmental hybrid dual-purpose cows under the principle of similar age, body weight, body condition at first time parturition, and at about 200 days in lactation period. The cows were divided into 6 experimental groups which have 10 cows each. The basal diet composed of corn silage, alfalfa meal, wheat straw and concentrates. The experimental groups were given diets with different percentage of ensilaged apple pomace instead of same weight of corn silage(5kg、10kg、15kg、20kg、25kg). The results showed that, the milk production and milk quality indices, such as milk fat percentage, milk protein percentage of the ensilaged apple pomace added groups improved at different degree. Moreover, the group with 50% ensilaged apple pomace added improved significantly(P<0.05). However, There were no significant differences in the percentage of lactose and nonfat solid(P>0.05)markedly. Ensilaged apple pomace could improve milking performance and milk quality of simmental hybrid dual-purpose cows at certain degree which varies with the amount of ensilaged apple pomace.
