摘  要:
水貂发情时间相对短而集中,因此配种方式对水貂生产效果有明显影响。试验选取140只2009年所产未满1岁标准母水貂按照7种不同方式(A、B、C、D、E、F、G)进行配种,以传统方式为基础进行差异显著性比较。结果发现,7种方式胎产仔数无显著性差异;A与F、C与G方式妊娠期差异极显著(P=0.0009;P=0.0004);A与E、C与G产仔日期差异显著(P=0.0119;P=0.0253)。各繁殖指标比较结果表明,A、B和C方式可代替传统方式并不影响繁殖效果;连续配种刺激、刺激频率及间隔一个周期进行配种等因素可能有助于胚泡着床从而缩短妊娠期。

摘  要:
The study was conducted in one hundred and 140 minks that were birth in 2009,which accorded to seven different mating systems(A,B,C,D,E,F and G),and then compared the significant difference on the basis of the traditional way.The results showed that the litter size were not significant;the pregnancy was highly significant difference in between A and F,between C and G(P=0.0009;P=0.0004);the difference of birthing date was significant in between A and E,between C and G(P=0.0119;P=0.0253).It also suggested that A,B and C could replace the trational way and not affect results through comparing the breeding indexes.Furthmore,factors such as continued mating stimulus,stimulative frequency and mating at intervals of one cycle may contribute to the implantation of embryo,and then shorten the pregnancy.
