【摘要】：为提高伊拉兔工厂化生产的繁殖效率,随机选取某兔场2 334只母兔,分为3组,带仔数分别设定7、8、9,测定受胎率;同时对该场15 000只母兔不同月份和季节的受胎率进行统计分析。结果表明,带仔数7和8的母兔受胎率分别为74.48%和73.36%,差异不显著,而带仔数9的母兔受胎率为52.56%,显著低于带仔数7、8的母兔;冬、春季母兔受胎率分别为74.39%和74.49%,均略高于夏秋季(72.63%,72.10%),但差异不显著;在各月份中,每年4月是母兔受胎率最高的季节,达76.63%,显著高于10月的69.11%。综上,为保证集约化养殖中伊拉兔受胎率,建议母兔的适宜带仔数为8,同时要加强夏、秋季配种管理。
[Abstract]:In order to improve the reproductive efficiency of the factory production of Yira rabbits, 2 334 female rabbits were randomly selected from a certain rabbit farm and divided into 3 groups. At the same time, the pregnant rates of 15 000 female rabbits in different months and seasons were statistically analyzed. The results showed that the conception rates of female rabbits with litter size 7 and 8 were 74.48% and 73.36 respectively, and the difference was not significant. The pregnant rate of female rabbits with litter size 9 was 52.56, which was significantly lower than that of female rabbits with litter size 74.49 in winter and spring, which was slightly higher than that of 72.63 in summer and autumn, but the difference was not significant. In order to ensure the conception rate of Yira rabbits in intensive culture, the suitable size of female rabbits should be 8, and the management of breeding in summer and autumn should be strengthened.
