摘要
在基础日粮相同的情况下,试验组采用苜蓿草颗粒,对照组采用铡碎的苜蓿干草,对12头1岁西杂公牛进行60 d育肥试验。测定分析了两组牛的体重、日增重及经济效益,以比较苜蓿的不同调制方法对育肥效果的影响,试验结果表明:头均日增重试验组0.95 kg,比对照0.72kg提高了31.84%(P<0.01),经济效益试验组比对照组提高了54.3%(P<0.01)。因此选择苜蓿草颗粒进行西杂公牛的育肥效果较好。
Under the same base diet , 12 one-year-old Simmental crossbred bulls were feed granulated alfalfa（treatment group） and pulverized alfalfa hay（controlled group） respectively during 60 days, to compare the effect of different method of modulating alfalfa on fattening results with the aid of testing and analyzing body weight, average daily gain（ADG） and profits of both the two group cattle. The results showed that ADG of the treatment group （0.95 kg） was 31.84% more than that of control group （0.72 kg）（P 0.01） ,the economic analysis suggested the profits of the treatment group was 54.3% higher than that of control group（ P 〈0.01）. In conclusion, fed effect of granulated alfalfa was better than that of pulverized alfalfa for Simmental crossbred bulls.
