长毛兔养殖场对温度的要求
发布日期:2017-03-07 来源:http://www.myxinhua.com 发布人:admin
毛兔汗腺极不发达,体表又有浓密的被毛,所以对环境温度非常敏感。据试验,子兔的更适温度为30℃~34℃,幼兔为20℃~24℃,成年兔为15℃~19℃。建舍时要考虑环境温度。不过兔为维持体温,需消耗较多营养,如不能满足所需营养,则对产毛和增重都有明显影响。
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.
据试验,长毛兔采毛前后对环境温度的要求差别较大。采毛前因被毛长密,体热散失少;采毛后因体表毛短,散热量可增加30%以上。所以,寒冷季节采毛后必须做好保温工作,以防感冒,但在采毛4周后,可保持环境温度在5℃~14℃之间,以利促进兔毛生长,提高兔毛产量。
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 光照对长毛兔的生理机能有重要调节作用。适宜的光照有助于增强长毛兔的新陈代谢,增进食欲,促进钙、磷的代谢作用;光照不足则可导致长毛兔的性欲和受胎率下降。此外,光照还具有、保持兔舍干燥和预防疾病等作用。生产实践表明,公母兔对光照要求是不同的。一般而言,繁殖母兔要求长时间光照,以每天光照14小时~16小时为好,表现为受胎率高,产子数多,可获得更佳的繁殖效果。
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.
种公兔在长时间光照条件下,则精液品质下降,而以每天光照10小时~12小时效果更好。目前,小型兔场一般采用自然光照,兔舍门窗的采光面积应占地面的15%左右,但要避免太阳光的直接照射;大中型兔场,尤其是集约化兔场多采用人工光照或人工补充光照,光源以白炽灯光较好,每地面3瓦~4瓦,灯高一般离地面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.
