摘要
对乌鲁木齐种牛场562头新疆褐牛1997年至2003年奶牛的产犊间隔、产奶量、产犊季节、产犊胎次、犊牛初生重、犊牛性别、体尺等基础资料进行统计分析,分析研究了上述各因素与产奶量之间的关系。为有计划的开展配种工作和提高奶牛的终生产奶量提供科学依据。结果表明:产犊间隔、产犊季节、胎次、体斜长对产奶量有极显著的影响(P<0.01);犊牛性别、体高、胸围对产奶量无显著影响(P>0.05)。综合分析认为新疆褐牛适宜的产犊间隔为410d,适宜的产犊季节为秋、冬季。
Individual data of 562 Xinjiang Brown Cattle from Urumqi Breeding Cattle Farm during the year from 1997 to 2003 were collected and information of calving interval, milk production , calving season, parity, birth weight ,calve sex and body measurement were analyzed to determine the effect of above -mentioned factors on milk production. The result showed that there was a extremely significant association between calving interval, calving season, parity and body length and milk production （P 〈0.01）. while there was no significant correlation between calve sex, body height, chest circumference and milk production（P 〉0.05）.
