摘  要：
选择21日龄断奶仔猪360头,随机分为4个处理组,处理组1和2日粮粗蛋白水平为20%,处理组3和4日粮粗蛋白水平为18%,处理组2和4日粮添加枯草芽孢杆菌。试验期为断奶后14d。结果显示,断奶后第1周,处理组2仔猪的平均日增重和平均日采食量显著大于处理组1(P<0.05),与处理组3和4相比差异不显著(P>0.05);处理组4仔猪腹泻率最小。从试验全期看,日粮添加枯草芽孢杆菌的处理组2和4仔猪的平均日增重显著高于处理组1和3(P<0.05)。试验结果表明,断奶仔猪过渡料低水平粗蛋白设置有利于减少断奶仔猪腹泻,同时添加枯草芽孢杆菌对改善早期断奶仔猪的生长性能有良好效果。

摘  要：
Three hundred and sixty weaning piglets(21 days)were assigned four experimental treatments.The diet protein level of group 1 and 2 was 20%,and the diet protein level of group 3 and 4 was 18%.The feed additive Bacillus Subtilis were used in group 2 and 4.The experimental period was 14 days after weaning.During the weaning of 7 days,the average daily gain and feed intake of group 2 piglets were higher(P < 0.05)than those of group 1,and were similar with group 3 and 4(P > 0.05).The diarrhoea ratio of group 4 piglets was lowest among four groups.During the period of experimental days,group 2 and 4 piglet fed Bacillus Subtilis had higher average daily gain than those of group 1 and 3.These findings proved that the lower diet protein level could decrease the piglet diarrhoea,and feed additive Bacillus Subtilis could improve the growth performance for early-weaned piglets.
