摘要

CVM(复杂椎体畸形)和短脊柱畸形(BY)是近二十年来世界各地荷斯坦奶牛最常见的常染色体隐性遗传缺陷。从2004年和2014年开始，分别对3035头和338头波兰荷尔斯泰因-弗里西亚公牛进行CVM和BY携带者检测。其中CVM携带者191例(6.29%)，BY携带者20例(5.92%)。从2016年开始，没有观察到CVM携带者，而在过去的5年里，每年只发现单一的BY携带者。一个公牛变成了双CVM/BY载体，也是双CVM/BY荷兰顶级父系(JABOT 90676-4-9)的儿子。结果表明，波兰奶牛的CVM和BY缺陷实际上已被根除，但如果在母系或母系中意外出现CVM或BY携带者的新公牛，则应继续进行附带检测。

Eradication of carriers of Complex Vertebral Malformation (CVM) and Brachyspina in Polish Holstein-Friesian bulls.

CVM ( Complex Vertebral Malformations) and Brachyspina (BY) are the most common autosomal recessive genetic defects occurring in the last two decades in Holstein dairy cattle around the world. Beginning from 2004 and 2014, 3035 and 338 Polish Holstein-Friesian bulls were tested to find carriers of CVM and BY, respectively. Among analyzed bulls 191 CVM carriers (6.29%) and 20 BY carriers (5.92%) were identified. No CVM carriers were observed beginning from 2016, whereas only single BY carriers was identified annually for the last 5 years. One bull turned to be double CVM/ BY carrier as a son of also double CVM/BY top Dutch sire (JABOT 90676-4-9). It is shown that CVM and BY defects are practically eradicated from Polish dairy cattle although incidental testing should be continued if new bulls with CVM or BY carriers in sire or dam pedigree will unexpectedly appear.
