双雌配对鸽繁殖力的测定
Determination of the Fecundity of Female-Female Pairing Pigeons
摘要
Abstract
This experiment was conducted to study the best match time of female-female pairing white king pigeons and the effect of hens under female-female paring on reproductive performance.216 white king pigeons (72 cocks and 144 hens) were randomly divided into four groups (after respectively paired 2,3,4,5 months later, female-female pairing pigeons exchange with hens of the corresponding male-female paired pigeons) and every group has 9 pairs of female-female pairing and 18 pairs of male-female pairing.The production interval of female-female paired pigeons at different pairing period and female-male paired pigeons after reaching double female mating cycle of demolition were recorded.The fertility breeding, hatching and 0,7, 14, 21-day weight of hens of male-female pairing were also recorded.The results showed that the production interval of different pairing cycle of female-female paired pigeons had no significant difference (P>0.05) and became longer after pairing four months.The production interval of male-female pairing declined compared to the previous after pairing two months.The fertilization rate and hatching rate of hens were significantly lower than that after pairing four months.The weight of different-age pigeons of different pairing cycles has no significant difference (P>0.05).To sum up.the best matching time of female-female pairing is four months.关键词
