本试验旨在探讨在哺乳母猪日粮中添加缬氨酸和异亮氨酸对母猪及其仔猪生产性能、母猪采食量和乳成分的影响.试验选用健康、体况、预产期相近的第2胎法系JALAX母猪144头,分成3个处理组,即对照组、试验A组和试验B组,每个处理48头母猪.对照组饲喂基础日粮,试验A组饲喂添加低水平支链氨基酸日粮(基础日粮+缬氨酸0.26%+异亮氨酸0.06%),试验B组饲喂添加高水平支链氨基酸日粮(基础日粮+缬氨酸0.36%+异亮氨酸0.14%).试验从母猪妊娠108 d进产房开始,到仔猪21日龄断奶时结束.试验结果表明:(1)添加缬氨酸和异亮氨酸提高了仔猪的断奶窝重、断奶窝增重、平均日增重和21日龄仔猪成活率,但以试验A组的效果较好,...

This study was to explore the effects of valine and isoleucine on production performance of sows and litters, feed intake and mile composition of sows. One hundred and forty-four France hybrids galaxy JALAX Sows, with similar health, situation and expected date of delivery, were randomly divided into 3 groups, namely group1 （control group）, 2 and 3, with each group containing 6 replicates of 8 sows. Groups 1 to 3 were fed with basal diets supplemented with 0, 0.26% and 0. 36% of valine and 0, 0.06% and 0.14% of isoleucine respectively. On the...
