摘要
为调查绥德县奶牛的繁殖状况,笔者于2004～2010年间对该县繁殖奶牛进行了年度平均繁殖周期及胎次平均繁殖周期的统计。结果表明,该县奶牛年度平均繁殖周期为409.6～427.1d,胎次平均繁殖周期为411.8～420.1d,均低于全国平均水平。绥德县需结合实际情况,进一步加强相关人员的培训,提高奶牛饲养管理的整体水平。
According to the survey of breeding conditions in cows from the 2004 to 2010 in Suide county,the average reproductive days and the average reproductive days of each birth during seven years have been counted.We give some suggestion in how to reduce the cow breeding cycle according to the local analysis of the detail situation.
