| Abstract: | 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. |
