摘　　要：为探究不同光照条件对42 d繁殖模式的哺乳母兔繁殖性能的影响,设置白、红、黄、绿、蓝、紫6种光色和60 lx、80 lx、100 lx 3种光照度之间交叉组合对母兔进行诱导发情。结果表明,在红光组母兔受胎率(52.0%)和泌乳力(21日龄窝质量3.69 kg)均显著大于紫光组的母兔受胎率(16.7%)和泌乳力(21日龄窝质量3.36 kg),黄光组母兔产活仔数(11.85个)和初生窝质量(0.75 kg)显著高于紫光组产活仔数(7.7个)和初生窝质量(0.55 kg)。60 lx光照度下,母兔在包括受胎率、产活仔数、初生窝质量、仔兔平均日增质量、泌乳力上均表现较好性能,其中60lx组受胎率(38.8%)和仔兔平均日增质量(25.70g)上显著高于80 lx组的受胎率(24.5%)和仔兔平均日增质量(24.8 g)。表明哺乳母兔在波长较长的红黄色光和较低的60 lx的光照度下最适宜繁殖。光色和光照度对母乳母兔繁殖性能无显著互作效应。In order to explore the effects of different light conditions on the reproductive performance of the 42-day reproductive model of lactating female rabbits,the cross combination of six kinds of light color(white,red,yellow,green,blue,purple)and three kinds of illuminance(60 lx,80 lx,100 lx)were used to induce estrus in female rabbit.The results showed that the fertility rate(52.0%>16.7%)and lactescence(21-day-old nest mass 3.69 kg>3.36 kg)of the female rabbits in the red light group were significantly higher than those in the purple light group,the alive litter size(11.85>7.7)and starting litter mass(0.75 kg>0.55 kg)of the female rabbits in the yellow light group were significantly higher than those in the purple light group.At 60 lx light illuminance,the female rabbits showed better performance in the fertility rate,alive litter size,starting litter mass,average daily gain of newborn rabbits,and lactescence.And the fertility rate of the female rabbits(38.8%>24.5%)and average daily gain of newborn rabbits(25.70 g>24.8 g)in 60 lx group were significantly higher than those in the 80 lx group.The results indicated that the lactating female rabbit was the most suitable for reproduction under long wavelength red or yellow light and low 60 lx light illuminance.Light color and light illuminance had no significant interaction effect on reproductive performance of lactating female rabbits.
