摘要
在８个多月（１２月至翌年８月）内给放牧绵羊口服营养菌剂１７次（每半月服用一次），试验羊比对照羊增重多３１．２６％；舍饲羊在７个月内口服营养菌剂１４次（每半月服用一欢），试验羊比对照羊增重多３１．１３％，证明绵羊较长期服用营养菌剂仍有增加体重的作用，在冬春季节可以减少春乏死亡。并证明试验羊与对照羊的屠宰率、干肉率和羊毛生长长度基本一致，而且长期服用菌剂的绵羊未发现有不良反应。
Nutritional Bacteria mixture was orally given to grazing sheep as well as to rearingsheep at a 15 day intervals in a long time period( 8 months for grazing sheep from December toAugust,in the next year,7 months for rearing sheep).The body gain of grazing and rearingsheep fed the bacteria increased by 3 1.26% and 31.13% respectively as compared with con-trolled sheep,indicating that orally taking nutritional bacteria in long time may accelerate bodygain·It was proved that the bacteria may red uce mortality and has no harmful effect to thesheep.However,no differences in dressing percentage·dry meat rate,and wool length betweenexperimental and controlled sheep was found.
