摘要/Abstract

摘要： 为提高繁育性能,实现一年一产,增加养殖效益,本文在西藏自治区仲巴县选择了30 头健康怀孕吉拉金丝牦牛开展对比补饲试验,对其生产的牦犊牛实施早期断奶试验。试验结果显示,对怀孕吉拉金丝牦牛补饲,在怀孕天数上,试验组与对照组差异不显著;在产后配种间隔天数上,对照组间隔148 天,试验Ⅰ组间隔83 天,试验Ⅱ组间隔87 天,试验Ⅰ、Ⅱ组较对照组差异显著。对牦犊牛进行早期断奶,对比牦犊牛初生重和60 日龄日增重,对照组、试验Ⅰ、Ⅱ组差异不显著;对比60 日龄断奶到180 日龄日增重,试验Ⅰ、Ⅱ组较对照组差异显著;180 日龄对照组平均日增重为248.197 2 g,试验Ⅰ组平均日增重为406.979 6 g,试验Ⅱ组平均日增重为399.994 4 g。在经济效益方面,10月龄青年牦牛试验组较对照组增加效益4 500 元/头。

Abstract: In order to improve the breeding performance, achieve one production per year and increase the breeding benefits, 30 healthy pregnant Gila golden silk yaks were selected in Zhongba county, Tibet autonomous region to carry out a comparative supplementary feeding test, and the early weaning test was carried out on their yaks. The results showed that there was no significant difference in the days of pregnancy between the experimental group and the control group.There was 83 days in the experimental group and 87 days in the experimental group on the days between postpartum breeding. The difference between the control group and the experimental groups Ⅰ and Ⅱ was significantly. There was no significant difference in birth weight of yak calf and daily gain of yak calf at 60 days of age between control group and experiment group Ⅰ and Ⅱ. Compared with the control group,the daily gain from weaning at 60 days of age to 180 days of age was significantly different in experimental groups Ⅰ and Ⅱ. The average daily gain was 248.197 2 g in control group,406.979 6 g in test group Ⅰ and 399.994 4 g in test group Ⅱ at 180 days of age. In terms of economic benefit,the experimental group increased by 4 500 yuan/head compared with the control group.

Key words: Gila Golden Yak, supplementary feeding, early weaning of calves, improvement of production performance
