仿生产仔箱对家兔繁殖性能及母性行为的影响

为了满足福利养兔和严寒地区家兔繁殖生产的需求,对根据家兔生物学特性研制出的仿生产仔箱进行使用效果研究。结果表明,仿生产仔箱有提高巢箱温度的作用,每日早、中、晚分别较外挂式产仔箱提高1.85,2.04,2.57℃(P0.01);部分繁殖性状指标提高。使用仿生产仔箱的母兔泌乳力、断奶数及成活率均较高,母兔拉毛时间提前,拉毛数量有增加的趋势;哺乳期间母兔护仔能力也增强,母兔、仔兔均可得到较好的休息。仿生产仔箱能满足寒冷地区兔群繁殖的需要,符合福利养兔对产仔窝的要求。

Effect of Biomimetic Litter Boxes on Reproductive Performance and Maternal Behavior of Rabbit

To meet the requirements of welfare breeding and productivity in cold region rabbit, the effect of biomimetic litter boxes which developed on the basis of biological characteristics of rabbit was studied. Two treatment groups used external litter boxes and biomimetic litter boxes respectively. The experiment results showed that： biomimetic litter boxes could increase the temperature of the nest box and the temperatures were higher than external litter boxes by 1.85, 2.04, 2.57 ~C （P 〈 0.01 ）in the morning, midday noon and evening; some reproductive traits were improved, the 21 days weights of litter, weaners and survival rates of biomimetic litter boxes were higher; the napping time of biomimetic litter boxes was advanced, the napping quantity had an increasing trend. During the course of lactation, matemal ability was increased. This study showed that biomimetic litter boxes could meet the requirements of the breeding productivity in cold region, and in keeping with the requirements of welfare breeding.
