摘　　要：[目的]为提高人工冻配受胎率,降低肉牛饲养成本,提高肉牛养殖经济效益。[方法]通过对冻配不同部位、不同时间及解冻温度等进行统计分析。[结果]结果表明,在发情结束后4～6 h,输精部位在子宫角1/3处,解冻温度为40℃输精,母牛的受胎率为最高。In order to improve the rate of artificially frozen mating, reduce the feeding cost of beef cattle, and improve the economic benefit of beef cattle breeding, statistical analysis was carried out on different parts of frozen mix, different time and thawing temperature. At the end of estrus 4 hours after estrus, the position of insemination was at 1/3 of uterine horn, the thawing temperature was 40 ℃, and the conception rate of female cattle was the highest.
