摘  要:
通过对青海省互助八眉猪保种场2000—2008年的配种产仔记录统计分析表明,该场不同品种的配种间隔介于21.80~27.60d,平均配种间隔为25.02d;配种间隔随胎次增加而缩短;不同品种猪在同一胎次的配种间隔无显著差异(P>0.05)。通过对2008年128头次母猪在一个情期内的发情配种记录分析得出,该场母猪在一个情期内主要集中在断奶后6~8d内发情配种,并且该期间的情期受胎率也较高;同时母猪的配种间隔与季节有一定的关系,在春、夏、秋季较短,冬季较长。

摘  要:
Based on the data from Huzhu Bamei species farm from 2000 to 2008,the analysis showed that breeding interlude in different variety was at 21.80 to 27.60 days,the average breeding interlude was 25.02 days,the breeding interlude decreased with the increase of fetus numbers,however there was no different signifcance at the same fetus number in different variety(P >0.05).By analysis of 128 sows breeding at the same time in 2008,the result indicated that the empathema breeding intensively was at post-weaning 6~8 d in the same oestrus,and the conception rate also was high.Additionally,it was related to season to a certain degree with the feature that it is shorter in spring,summer,autumn and longer in winter.
