小兔子出生时没有毛,第四天开始长毛。头发长得很快。经测定,幼兔全耳毛发发育正常,1月龄,毛发长度可达4.2 cm;细毛长度可达2.8厘米,乳毛已全部形成;在60天时,粗毛达到7.5厘米,细毛达到4.5厘米。90日龄时,毛发纤维生长速度与成年家兔相同,日、夜毛发平均生长速度为0.6-0.7 mm。剪掉毛后,大约需要75到90天的时间才能使被毛长回更佳长度。因此,长毛兔一年可以剪4-5次。实验表明,毛兔每单位体重产毛量是绵羊的2 - 3倍,所需营养是绵羊的1/3。
  The little rabbit was born without hair and began to grow on the fourth day. Hair grows fast. The hair development of the whole ear of the young rabbit was normal. At the age of one month, the length of the hair was up to 4.2 cm; the length of the fine hair was up to 2.8 cm, and the milk hair was all formed; at 60 days, the coarse hair was up to 7.5 cm, and the fine hair was up to 4.5 cm. At the age of 90 days, the growth rate of hair fiber was the same as that of adult rabbits, and the average growth rate of day and night hair was 0.6-0.7 mm. It takes about 75 to 90 days for the coat to grow back to its optimum length after shearing. Therefore, the hairy rabbit can be cut 4-5 times a year. The experiment shows that the wool yield per unit weight of wool rabbit is 2 - 3 times that of sheep, and the nutrition requirement is 1 / 3 of that of sheep.
  兔毛的生长受到许多因素的制约
  The growth of rabbit hair is restricted by many factors
  一是受品种的影响,兔毛的产量和质量随品种或品种的不同而不同。
  One is affected by varieties. The output and quality of rabbit hair vary with varieties or varieties.
  其次,受个体影响,体重与毛发的产生是成正比的,个体越大,身体越大,表皮面积越大,毛发的产生就越高。
  Secondly, affected by the individual, the weight is directly proportional to the production of hair. The larger the individual is, the larger the body is and the larger the skin area is, the higher the production of hair is.
  三是受性别影响,一般雌性兔子产毛量高于雄性兔子产毛量。母兔在妊娠期和哺乳期毛发生长缓慢。
  Third, affected by gender, the hair production of female rabbits is generally higher than that of male rabbits. The hair growth of female rabbits was slow during pregnancy and lactation.

  四、受年龄影响。幼兔毛发少,质量差。头发在2-3岁时大量生长。3年后,毛产量逐渐下降,质量也下降。毛发的生长规律是,从幼兔到成年兔,兔毛由细到厚;老兔子的毛比小兔子的毛短。
  4、 Affected by age. Young rabbits have less hair and poor quality. Hair grows abundantly at the age of 2-3. Three years later, the gross output and quality of the products decreased. The growth rule of hair is that from young rabbit to adult rabbit, the hair of rabbit is from thin to thick; the hair of old rabbit is shorter than that of small rabbit.
  5. 受生理条件和生理因素的影响。身体虚弱或疾病会抑制兔毛的生长;兔毛的生长是由神经系统控制的。性腺和垂体的内分泌活动直接影响兔毛的产量和质量。例如,去势的雄兔兔毛生长快,密而细,产量高。
  5. Affected by physiological conditions and factors. Weakness or disease can inhibit the growth of rabbit hair, which is controlled by the nervous system. The endocrine activities of gonad and hypophysis directly affect the output and quality of rabbit hair. For example, the hair of castrated male rabbit grows fast, dense and fine, and its output is high.
