摘要:
对宁夏中地生态牧场奶牛淘汰原因与胎次和月份关系进行了研究,结果发现在2015年和2016年中,乳腺疾病、肢蹄病和消化系统疾病均是引起贺兰中地生态牧场奶牛淘汰的主要因素;淘汰率最高的月份均为5月份,2015年第2胎的淘汰率最高,2016年第1胎的淘汰率最高.奶牛的淘汰原因与胎次和月份均差异不具有统计学意义,但淘汰原因与月份有一定的相关性.

Abstract:
The relationship of the causes for dairy cattle culling at Helan Zhongdi Ecological Ranch in Ningxia with parity and month was studied so as to provide some guidance in production. The results showed that breast disease, limb hoof disease and digestive system diseases were the main factors responsible for dairy cow culling in Helan Zhongdi Ecological Ranch in 2015 and 2016. Highest culling rate occurred in May of both years, and the 2nd parity had the highest culling rate in 2015, while the 1st parity had the highest culling rate in 2016. The reasons of dairy cattle culling with parities and month were not significantly different (p>0.05), but dairy cattle culling was, to some extent, correlated with the month.
Key words:  dairy cattle  cause for culling  parity  month
