饲养模式对牦牛适时出栏效率的影响

Effect of Feeding Mode on Timely Slaughter Efficiency of Yak

旨在研究饲养模式对牦牛出栏周期和经济效益的影响。试验选择体质量接近和健康的同年生帕林公牦牛(帕里牦牛♂×林周牦牛♀)160头,分别对试验组(半舍饲养殖)牦牛60头和对照组(传统放牧)牦牛100头开展6月龄、18月龄、30月龄、42月龄和54月龄的体质量测定。结果表明:从生长性能分析,5个年龄段试验组牦牛体质量均显著高于对照组牦牛(p<0.05);从经济效益分析,试验组牦牛比对照组牦牛平均单头多增加收益702元。综上,犊牦牛采取“全哺乳兼早期断奶技术”饲养,结合育成牦牛在冷季采取半舍饲养殖的方式能够增加牦牛生产周期,提高牦牛养殖经济效益。

The purpose is to study the influence of feeding mode on the slaughter cycle and economic benefits of yak. One hundred and sixty healthy male yak(Pali yak♂× Linzhou yak ♀),borned in the same year with similar weight,were selected for carrying out the experiment. The weight of sixty yaks in the experimental group(half pen feeding)and one hundred yaks in the control group(traditional grazing)were measured at the age of6months,18 months,30 months,42 months and 54 months,respectively. The results showed that the weight of yaks in the experimental group was significantly higher than that in the control group(p<0.05). From the economic benefit analysis,the average income of the experimental group was702 yuan more than that of the control group. In total,the feeding mode including "full lactation and early weaning technology" for newborn calves,and the bred yaks to grow up in the cold season with half pen feeding,will increase the production turnover and the economic benefits of yak.
