奶牛是一种世代间隔长(3~4年)、繁殖率低(每年1胎,每胎1头)的畜种,利用目前的人工授精(AI)育种体系,由于大规模后裔测定耗费大量人力、物力、财力,而且遗传进展也受到限制。因此,探索一套高效、快速的良种繁育扩繁体系具有重要的意义。河南花花牛集团牧业有限公司在总结了国内外常规奶牛繁育技术和多年实践经验的基础上,充分考虑河南省奶牛繁育工作的现状,形成了一套荷斯坦良种奶
Dairy cows are a breed of breeds that are long (3-4 years old) from generation to generation and have a low rate of reproduction (one child per year, one for each birth), using current AI systems for large-scale descendants , Material and financial resources, and genetic progress is also limited. Therefore, it is of great significance to explore a set of efficient and rapid propagation and propagation systems. On the basis of summarizing domestic and foreign conventional cow breeding technologies and years of practical experience, Henan Huabuoduo Group Animal Husbandry Co., Ltd. has fully considered the status of dairy cow breeding in Henan Province and formed a set of Holstein elite milk
