甘南牦犊牛全哺乳培育效果观察

Observation on the Effect of Whole Lactation Cultivation of Gannan Yak Calves

摘要:

本试验通过甘南牦犊牛全哺乳和限制哺乳+补饲的方式饲养,对比犊牛生长发育情况,分析总结甘南牦牛优质犊牛培育关键技术。结果表明,全哺乳公母犊牛6月龄体重分别达到82.58和77.65 kg,较限制哺乳公母犊牛分别增重10.54和11.13 kg,增重效果明显。全哺乳公母犊牛平均日增重达0.38和0.36 kg,而限制哺乳公母犊牛平均日增重仅为0.33和0.30 kg。由此可见,在甘南牧区实行全哺乳培育可使牦犊牛6月龄达到断奶体重实现早期断奶,同时可有效加速母牦牛体况恢复并在次年繁殖季节正常发情配种,实现牦牛一年一产。

Abstract:

This experiment compared the growth and development of Gannan yak calves through full lactation and restricted lactation+supplementary feeding,and analyzed and summarized the key technologies for cultivating highquality Gannan yak calves.The results showed that the 6monthold weight of fully lactating male and female calves reached 82.58 and 77.65 kg,respectively,which increased by 10.54 and 11.13 kg compared to restricted lactation male and female calves,with a significant weight gain effect.The average daily weight gain of all lactating male and female calves is 0.38 and 0.36 kg,while the average daily weight gain of restricted lactating male and female calves is only 0.33 and 0.30 kg.In conclusion,it can be seen that implementing full breastfeeding cultivation in the Gannan pastoral area can enable yak calves to reach weaning weight at 6 months of age and achieve early weaning.At the same time,it can effectively accelerate the recovery of female yaks?? physical condition and normal estrus mating in the following year??s breeding season,achieving annual production of yaks.
