摘要: 为了探讨非遗传因素对荷斯坦牛305 d产奶量的影响,笔者收集了新疆呼图壁种牛场牧一场1996-2005年度荷斯坦奶牛生产性能记录资料,通过采用SAS 8.1软件的最小二乘方差分析,分析了年度、季节、产犊间隔和胎次对荷斯坦牛305 d产奶量的影响。结果表明,年度、产犊间隔和胎次对产奶量的影响差异极显著(P<0.01);季节对产奶量的影响差异不显著(P>0.05)。本研究结果为进一步对遗传参数估计提供效应值划分的依据。

Abstract: The objective of this study was to investigate the effect of non-genetic on 305-day milk yield, datas of Holstein production records which contained the information from 1996 to 2005 were collected form Xinjiang Hutubi herd farm in Xinjiang, the effects of year, season, calving interval and parity on Holstein 305-day milk yield were analyzed by least squares means with SAS 8.1 system. Results showed that effect of year, calving interval and parity on 305-day milk yield were highly significant(P<0.01), effect of season for 305-day milk yield was not significant (P>0.05).The results provide a foundation of the division of the effect value to estimate genetic parameter furtherly.

Key words: Holstein cow; 305-day milk yield; year; season; calving interval; parity
