摘要

收集和分析了1989年至2012年期间出生的7782头Mehsana水牛的记录，这些水牛来自于古吉拉特邦的Dudhsagar研究与发展协会(DURDA)， Dudhsagar奶牛场，Dudhsagar, Mehsana。采用最小二乘分析对初泌乳产奶量(FLMY)、初泌乳脂肪量(FLFY)、平均脂肪率(AFP)和初产龄(AFC)的非遗传因素进行估计。FLMY、FLMY、AFP和AFC的最小二乘平均标准误差分别为1900.68±7.65 lit.、135.04±0.57 kg、7.11±0.11%和1407.18±4.36 d。各非遗传因素(产犊期、产犊季、初产组龄)对Mehsana水牛FLMY、FLMY和AFP均有极显著(P≤0.01)的影响。季节和出生期对AFC的影响极显著(P≤0.01)。值得注意的是，在马肉鸡品种评价方案中应考虑这些因素，因为它们对马肉鸡品种有很大的影响。

Effect of some non-genetic factors on productive and reproductive traits of Mehsana buffaloes

The records of 7782 Mehsana buffaloes sired by 184 sires maintained at Dudhsagar Research and Development Association (DURDA), Dudhsagar Dairy, Mehsana, Gujarat born during 1989 to 2012 were collected and analysed to examine the effect of non-genetic factors viz. period and season of calving and age at first calving. The least squares analysis was used for estimation of various non-genetic factors on First Lactation Milk Yield (FLMY), First Lactation Fat Yield (FLFY), Average Fat Percentage (AFP) and Age at First Calving (AFC). The least squares mean with standard error of FLMY, FLMY, AFP and AFC were estimated to be 1900.68±7.65 lit., 135.04±0.57 kg, 7.11±0.11 percentage and 1407.18±4.36 days, respectively. Highly significant (P≤0.01) effect of all the non-genetic factors (period and season of calving and age at first alving group) under study was observed on FLMY, FLMY and AFP in Mehsana buffaloes. Further, highly significant (P≤0.01) effect of season and period of birth was recorded on AFC. It is worthy to note that in Mehsana breed evaluation programme these factors should be considered as they have great influence of them.
