毛兔汗腺極不發(fā)達(dá)，體表又有濃密的被毛，所以對(duì)環(huán)境溫度非常敏感。據(jù)試驗(yàn)，子兔的更適溫度為30℃~34℃，幼兔為20℃～24℃，成年兔為15℃～19℃。建舍時(shí)要考慮環(huán)境溫度。不過兔為維持體溫，需消耗較多營養(yǎng)，如不能滿足所需營養(yǎng)，則對(duì)產(chǎn)毛和增重都有明顯影響。
Maotu sweat gland is not highly developed, surface and dense coat, it is very sensitive to environmental temperature. According to the experiment, the optimum temperature of the rabbit is 30 ~34, and the young rabbit is from about 20 DEG C to about 24 DEG C, and the adult rabbit is in the range of. Environmental temperature should be considered when building. However, in order to maintain the body temperature, rabbits need to consume more nutrients. If they can not meet the needs of nutrition, they have significant effects on the yield and weight gain.
據(jù)試驗(yàn)，長毛兔采毛前后對(duì)環(huán)境溫度的要求差別較大。采毛前因被毛長密，體熱散失少；采毛后因體表毛短，散熱量可增加30％以上。所以，寒冷季節(jié)采毛后必須做好保溫工作，以防感冒，但在采毛4周后，可保持環(huán)境溫度在5℃～14℃之間，以利促進(jìn)兔毛生長，提高兔毛產(chǎn)量。
According to the experiment, the requirements of the environment temperature of the Angora rabbit hair before and after the harvest are different. The hair coat is long ago by dense body heat loss due to surface mining; hair short hair, cooling capacity can be increased by more than 30%. So, the cold season production after Mao must do insulation work, to prevent colds, but the hair after 4 weeks, can maintain the ambient temperature at 5 DEG to 14 DEG C, in order to promote hair growth, improve the yield of rabbit hair.
光照 光照對(duì)長毛兔的生理機(jī)能有重要調(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。生產(chǎn)實(shí)踐表明，公母兔對(duì)光照要求是不同的。一般而言，繁殖母兔要求長時(shí)間光照，以每天光照14小時(shí)～16小時(shí)為好，表現(xiàn)為受胎率高，產(chǎn)子數(shù)多，可獲得更佳的繁殖效果。
Light illumination has an important role in regulating the physiological function of Angora rabbits. The appropriate light helps to enhance the Angora rabbit The new supersedes the old. stomachic, promote the metabolism, calcium and phosphorus; insufficient light can lead to Angora rabbit and the pregnancy rate decreased libido. In addition, it also has the function of sterilization, keeping the rabbit house dry and preventing disease. The production practice showed that the male and female rabbits had different illumination requirements. In general, reproductive female rabbits require long time light, with light per day from 14 hours to 16 hours for the good performance for the high pregnancy rate, birth number, can obtain the best effect of reproduction.
種公兔在長時(shí)間光照條件下，則精液品質(zhì)下降，而以每天光照10小時(shí)～12小時(shí)效果更好。目前，小型兔場(chǎng)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(chǎng)，尤其是集約化兔場(chǎng)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瓦~4瓦，燈高一般離地面2米~2．4米。
Under the condition of long time illumination, the quality of semen was decreased, and the effect of 10 hours to about 12 hours per day was the best. At present, small rabbit uses natural light, about rabbit house doors and windows lighting area should be accounted for 15% of the ground, but to avoid direct exposure to sunlight; large and medium-sized farm, especially the intensive use of rabbit artificial light or artificial lighting, light source with incandescent light is good, 3 watts per square meter of ground ~4 W, light high from the ground 2 meters ~2.4 meters.
