Abstract:
Healthy female rabbits aged 3.5 to 4.0 months were randomly divided into four groups:the white light group(control group A),the green light group(treatment group B),the red light group(treatment group C)and the blue light group(treatment group D)with 3 replicates in each group,and 12 rabbits in each replicate.The light intensity was set to 80 lx,and the light was 16 h per day for 6 days before artificial insemination.Three reproductive cycles were carried out to de-termine the reproductive performance of female rabbits under different light colors,such as the number of fetuses,total litter size,weaning litter weight and serum reproductive hormone content.The results showed that,according to the comprehensive statistics of three breeding cycles:(1)the melatonin levels in the green group and red group were significantly lower than those in white group(P<0.01),and the green group was significantly lower than the blue group(P<0.05);the levels of luteinizing hormone in green group and red group were significantly higher than those in white group(P<0.01);the follicle stimulating hormone in the green group was significantly high-er than in white group(P<0.05);the estradiol content in the green group was significantly higher than that in the white group and blue group(P<0.01),and significantly higher than that in the red group(P<0.05).(2)the conception rate of the group was significantly higher than that of the white group(P<0.01),and significantly higher than that of the red group and blue group(P<0.05).(3)the number of rabbits in the green group at 30 days of age was significantly higher than that in the red group and the blue group(P<0.05),and the litter weight at 30 days of age was significantly higher than that in the red group and the blue group(P<0.01),and significantly higher than that in the white group(P<0.05).In conclusion,the LED light belt is controlled by a dynamic light control system,the light intensity is set to 80 lx,and the light is 16 h a day for 6 d before artificial insemination.Green light can reduce the serum melatonin of Fujian white rabbits,which has the best comprehensive effect on the same period of conception rate and reproductive performance of Fujian white rabbits.
