平凉红牛母牛一年一胎繁育技术

为了研究母牛高效繁育技术对平凉红牛母牛繁殖效率和养殖效益的影响,从母牛产后第8天开始,试验组母子分离、定时哺乳、早期断奶,对照组随母哺乳、自然断奶。结果表明,试验组母牛主要在60 d内第一次发情,发情率76.7%,对照组母牛主要在90 d后第一次发情,发情率60%;试验组母牛90d内受胎率86.7%、第一次授精情期受胎率89.7%,分别比对照组高53.3%、6.4%。存栏能繁母牛120头的适度规模场,通过母牛一年一胎繁育技术措施每年可新增纯收益12.8万元,效益可观。

Breeding Technology of Pingliang Red Cattle with One Calf a Year

In order to explore the effect of high-efficiency cow breeding technology on the reproductive efficiency and farming benefits of Pingliang red cattle, from the 8th day after the cows gave birth, the experimental group took the technical measures of separation of mother and child, regular breastfeeding and early weaning while the control group the cows have been breastfeeding and weaned naturally. The results showed that the first estrus of the experimental group cows was mainly within 60 days, and the estrus rate was 76.7%. The cows in the control group first estrus after 90 days, and the estrus rate was 60%. The conception rate of cows in the experimental group within 90 days was 86.7%, and the conception rate during the first insemination period was 89.7%, which were 53.3% and 6.4% higher than those of the control group, respectively. A moderately large-scale farm with 120 suitable breeding cows, through the technical measures of one calf a year, the new net income can be increased by 128,000 yuan each year, which was considerable.
