摘要: 【目的】 研究高产奶牛与优秀种公牛关系,追踪高产奶牛系谱,找出优秀种公牛,为牛场挑选优秀种公牛冻精提供理论依据。【方法】 统计泌乳牛305 d产奶量超过万千克的种公牛女儿,并通过输精记录匹配其女儿父号,将种公牛女儿305 d产奶量过万千克头数与女儿总数比值排名在前18头优秀种公牛通过中国奶牛数据中心查询其后代女儿生产性能,并对其女儿生产性能数据进行分析。【结果】 65610339号种公牛女儿305 d产奶量超过万千克占其所有女儿总数比例最高,达到57.14%。将挑选的18头优秀种公牛通过中国奶牛数据中心查询,65382019号种公牛女儿平均蛋白率最高,为3.32%。65382094号种公牛女儿平均305 d乳脂量最高,为4.04%。65908265号种公牛女儿平均305 d产奶量最高,为10 644 kg。【结论】 追踪高产奶牛父号系谱,其有共同血缘,且大部分源于北美优秀种公牛。优秀种公牛女儿测定的优秀率非常高,经过严格筛选的种公牛冻精在遗传上更具有优势。

Abstract: 【Objective】 To study the relationship between high-yielding dairy cows and outstanding breeding bull. The pedigrees of high-yielding dairy cows are tracked to find out the outstanding breeding bull, which might provide a theoretical basis for the subsequent selection of frozen breeding bulls. 【Methods】 The 305-day milk yield of the lactating cows in the field which produced more than 10,000 kg of bulls and daughters were counted, and the daughter's father number was matched by the insemination record, and the bull daughter's 305-day milk yield was over 10,000 kg and the total number of daughters was ranked. The top 18 outstanding breeding bulls were asked by the Chinese Dairy Data Center to check the performance of their offspring daughters and to analyze their daughter's performance data. 【Results】 The number of milk in the 65610339 bull of the farm was more than 10,000 kg, and the proportion of all the daughters was the highest, reaching 57.14%. The selected 18 excellent bulls were queried through the Chinese Dairy Data Center. The average protein rate of the daughter of the 65382019 bulls was the highest, at 3.32%. The average milk fat of the daughter of 65382094 bulls was the highest (4.04%). The average milk yield of the daughter of the 65908265 bull had the highest milk yield of 10,644 kg in 305 days. 【Conclusion】 The pedigree of high-yielding dairy cows was traced and found to have a common bloodline, and most of them originated from the outstanding Breeding of bulls in North America. Through the measurement of the performance of the bull daughter, the excellent rate of the daughter's determination was very high, which might be seen that the rigorously selected species of bull frozen sperm was genetically more advantageous.

Key words: breeding bull; high-yielding dairy cows; genetic improvement
