【摘要】：试验旨在研究白羽王鸽双雌配对的最佳效应时间及双雌配对下母鸽状态对其繁殖性能的影响。试验选取白羽王鸽216只(种公鸽72只,种母鸽144只),随机分为4组(分别在配对2、3、4、5个月后,双雌配对鸽与对应的公母配对鸽的母鸽进行置换),每组9对双雌配对种鸽、18对公母配对种鸽。试验记录不同配对周期下双雌配对鸽的产蛋间隔,达到配对周期后双雌拆对再公母配对的产蛋间隔,公母配对下种鸽产蛋的受精率、孵化率以及乳鸽0、7、14、21日龄体重。结果表明:配对周期对双雌配对种鸽的产蛋间隔无显著影响(P0.05),双雌配对4个月后产蛋间隔开始变长;双雌配对2个月后的种鸽进行拆对再公母配对后的产蛋间隔较之前有所缩短;随着配对周期的延长,母鸽进行再配对后其受精率、孵化率在4个月后明显降低;不同配对周期对乳鸽体重的影响差异不显著(P0.05)。综上所述:双雌配对最佳配对周期为4个月。
[Abstract]:The aim of the experiment was to study the optimal effect time of double female pairing and the effect of the condition of double female pair on the reproductive performance of white feather pigeon. 216 white feather pigeons (72 male pigeons and 144 female pigeons) were randomly divided into 4 groups (4, 5 months later). Two female pigeons were replaced with corresponding female pigeons, and 18 pairs of male and female pigeons were matched in each group of 9 pairs. The egg spacing of double female pigeons in different matching periods was recorded. The egg spacing between female and male pairs after paired cycle was achieved. The fertilization rate, hatching rate and body weight of young pigeon at 14 ~ 21 days old were recorded. The results showed that pairing cycle had no significant effect on the egg spacing of double female pigeons, but the egg spacing began to increase after 4 months of double female pairing. After two months of double female pairing, the laying interval of female pigeons was shorter than that of the former, and the fertilization rate and hatching rate of female pigeons decreased after 4 months with the extension of the matching period. The effect of different matching cycles on the body weight of pigeon was not significantly different (P 0.05). To sum up, the best pairing period of double female pairing is 4 months.
