摘要
为研究冷季不同的育肥模式对天祝白牦牛育肥效益的影响,试验将20头3岁天祝白牦牛公牛随机分成AB两组育肥组,A组为暖棚栓系式育肥组,B组为敞篷自由采食型育肥组,以三个月为期,并对育肥前牦牛体重和育肥后牦牛体重平均日增重进行了测定,试验结果显示,在同样饲料饲喂的条件下,B组的育肥效果A育肥组,试验效果差异显著(P<0.01)。
To study the influence different of fattening models on Tianzhu white yak fattening performance in the winter,20 Tianzhu white bull yaks（3 years old）were divided into A and B groups randomly.Group A was fatten with greenhouse and tie-down feeding type.Group B was fatten with outdoor free feeding fattening,after three months.The weight of yak before fattening and the average daily weight of yak after fattening were measured.Experimental results showed that the fattening effect of group B showed significant difference when compared with group A,in the same feed feeding conditions（P〈0.01）.
