摘 要：
高能高蛋白补充料“乳倍利”能有效弥补高产奶牛泌乳早期能量负平衡和减少体况损失,提高奶牛的繁殖性能。试验在北京市三元绿荷奶牛养殖中心长阳三场进行,试验组牛群每天每头饲喂“乳倍利”1.5千克,不再饲喂原来自配的“高产牛补充料”和“钙皂”;对照牛群仍按原来的方法饲喂,即每天每头加2千克“高产牛补充料”和300克“钙皂”。试验组和对照组的基础日粮组成相同。基础日粮由精料、羊草、苜蓿干草、青贮、混合料及一些糟粕类组成。试验结果表明:试验组牛群体况评分平均比对照组牛群体况评分提高了0.33,差异不显著(p>0.05);第1次配种成功率提高了8％,差异不显著(p>0.05),产后出现第一次发情天数缩短了约12夭,差异显著(p<0.01);受胎率提高了10％,差异显著(p<0.01)。

摘 要：
High-energy and high-protein supplementary feed "Rubeili"developed by China Agricultural University can effectively
make up the energy negative balance and reduce body-condition loss,improve fertility perfor- mance of dairy cows.The experiment was conducted in ChangYang Dairy farm of Beijing Sanyuan Dairy Group,the amount of addi-tion "Rubeili"is 1.5kg,the control group was added with 2kg former supplementary feed,but the basie ration between the two groups are the same.As experimental results indicate:the experiment group 's body condition score was improved 0.33 than control group's (p>0.05);the successful pregnancy rate of the first time was improved 8%(p>0.01);the days of the oestrus after calving was shortened about 12 days(p<0.01)and the pregnancy rate was improved 10%(p<0.01).
