为缩短牦牛的饲养周期,提高出栏率和养殖效益,本试验将牦牛、犏牛和本地黄牛在相同条件下舍饲153天,其增重分别达到58.67±19.80、90.70±12.85 kg和54.33±8.98 kg,犏牛在生长速度上极显著高于牦牛和本地黄牛。舍饲育肥牦牛、犏牛和本地黄牛的增收效益分别为220.56、1 134.37元和-95.79元。舍饲育肥即能提高牦牛和犏牛的生长能力,增加牧民收益,又能减轻当地草场压力,对高原草地畜牧业发展有重要意义。
In order to shorten period of raising yak (Bos grunniens), and improve marketing rate and culture benefit, we feed yak, cattle-yak and cattle for 153 days in the same control condition. The results indicated that the weight of yak, cattle-yak and cattle increased by 58.67±19.80 90.70±12.85 and 54.33±8.98 kg/d, and the growth rate of cattle-yak was significantly higher than yak and cattle. Besides the benefit of yak, cattle-yak and cattle were respectively 220.56, 1134.37 and -95.79 yuan. It can be concluded that, fattening in shed not only improve growing ability of yak and cattle-yak, and increase revenue of the herdsmen, but also reduce the stress of native meadows, so it is important significance for the plateau animal husbandry development.
