摘要
用由５株活菌组成的营养菌剂口服牦牛后观察其增重效果。试验结果：冬春枯草季节，每隔半月口服菌剂１次，试验组平均增重－０．６２ｋｇ，对照组平均增重－５．４９ｋｇ，试验组比对照组少减重４．８７ｋｇ，差异显著（Ｐ＜０．０５）。表明应用菌剂可减少冬春枯草季节放牧牦牛的体重下降。
The Nutritional Bacteria preparation, made of 5 strains of live bacteria,was orally given to yak to investigate the effect on body gain.The body weight in experimental group,taken the preparation every half month in grass withered season,increased evenly by -0.62kg,and that in the control group increased evenly by-5.49kg ,the difference between them was significant(P<0.05).It indicates that the preparation is able to reduce weight loss of grazing yak in grass withered season.
