光照對長毛兔的生理機(jī)能有著重要調(diào)節(jié)作用。適宜的光照有助于增強(qiáng)長毛兔的新陳代謝.增進(jìn)食欲，促進(jìn)鈣、磷的代謝作用，光照不足則可導(dǎo)致長毛兔的性欲和受胎率下降。此外，光照還具有、保持兔舍干燥和預(yù)防疾病等作用。
Light the physiological function of the Angora rabbit plays an important regulatory role. The optimum light helps to enhance the Angora rabbit The new supersedes the old.. Increase appetite, metabolism and promote calcium, phosphorus, light deficiency can lead to Angora rabbit sexuality and pregnancy rate decreased. In addition, the light also has bactericidal, keep the effect of rabbit hutch drying and disease prevention etc..
生產(chǎn)實(shí)踐表明，公母兔對光照要求是不同的。一般而言，繁殖母兔要求長光照，以每天光照14~16小時(shí)為好，表現(xiàn)為受胎率高，產(chǎn)仔數(shù)多，可獲得更佳的繁殖效果。種公兔在長光照條件下，則精液品質(zhì)下降，而以每天光照10~12小時(shí)效果更好。
The production practice shows that the male and female rabbit is different to light. In general, reproductive female rabbits require long illumination light to every 14~16 hours for the good performance for the pregnancy rate is high, the litter number, can obtain the best effect of reproduction. Male rabbits in long photoperiod conditions, then decreased semen quality, using daily illumination 10~12 hours the best effect.
目前，小型兔場一般采用自然光照，兔舍門窗的采光面積應(yīng)占地面的15%左右，但要避免太陽光的直接照射;大中型兔場，尤其是集約化兔場多采用人工光照或人工補(bǔ)充光照，光源以白熾燈光較好，每地面3~4瓦，燈高一般離地面2~2.5米。
At present, small rabbit farm general use of natural light, about the rabbit house doors and windows of the daylighting area should be accounted for 15% of the ground, but to avoid the direct irradiation of sun light; large and medium-sized farm, especially intensive rabbit farm use artificial light or artificial light supplement, light to incandescent light is good, per square meter of ground 3~4 watts, general 2~2.5 meters high from the ground lamp.
