微生态制剂对育肥牛增重效果的影响

Effect of microecological preparation on weight gain of fattening cattle

为研究微生态制剂对育肥牛增重效果的影响,本试验选取18头21月龄左右、平均体重为470±32.5 kg的夏洛莱杂牛作为试验对象,随机分为2组:对照组(饲喂基础日粮+单一酵母)和试验组(饲喂基础日粮+复合微生态制剂),比较各组育肥牛增重情况。结果发现,与对照组相比,试验组内育肥肉牛的平均日增重显著提高,料重比显著降低,提高了育肥肉牛的饲料转化效率。由此可见,与单一酵母饲料添加剂相比,复合型微生态饲料添加剂可以显著提升育肥肉牛增重,提高养殖场经济效益。

In order to study the effect of microecological preparation on the weight gain of fattening cattle, In this experiment, 18 charolai hybrid cattle aged about 21 months with an average body weight of 470±32.5 kg were selected as subjects and randomly divided into 2 groups:Control group(basal diet+single yeast) and experimental group(basal diet+compound microecological preparation), the weight gain of fattening cattle in each group was compared. The results showed that, compared with the control group, the average daily gain of fattening beef cattle in the experimental group was significantly increased, the feed to weight ratio was significantly reduced,and the feed conversion efficiency of fattening beef cattle was improved. Thus it can be seen,compared with the single yeast feed additive, the compound microecological feed additive can significantly improve the weight gain of fattening beef cattle and improve the economic benefits of the farm.
