种质和饲养是决定任何动物生长发育和生产性能的两个更重要的因素,也是影响毛用兔产毛性能的两个更重要的因素,所以设计长毛兔饲料配方时也应当以饲养标准为依据。在长毛兔的配合饲料中,更重要的养分是含硫氨基酸,胱氨酸。

Germplasm and breeding are the two most important factors to determine any animal growth and production performance, is the two most important factors influencing wool rabbit production performance, so the design of Angora rabbit feed formula should also to raise standards. In line with the feed Angora rabbit, the most important nutrients is a sulfur-containing amino acid, cystine.

兔毛中含硫氨基酸15%,而一般配合日粮中含硫氨基酸不能满足高产毛的需要,因此在日粮中加人0.7%的蛋氨酸可提高产毛量20%。全价配合饲料中个别微量元素仍不能满足兔高产毛的需求,所以在日粮中加人适量的铜、铁、锌可促进角质化蛋白的生成,提高产毛量。据研究,在每公斤日粮中添加铜30毫克、铁20毫克、锌10毫克可提高产毛量27%,另外添加硫酸钠0.2%,刺激胃肠粘膜,可起到一定的健胃作用并能补充饲料中的硫元素的含量。饲喂啤酒糟:啤酒糟中富含维生素和大量菌体蛋白,在兔日粮中加人40%鲜啤酒糟可明显提高产毛量,还可降低饲养成本,提高经济效益。

The sulfur-containing amino acids 15% rabbit hair, generally with sulfur-containing amino acids can not meet the needs of high dietary hair, so the increase in dietary methionine can increase 0.7% wool 20%. The price with the individual trace elements in feed still can not meet the high demand of rabbit hair, so the increase in dietary amount of copper, iron, zinc can generate horny protein, improve the yield of wool. According to the research, with the addition of copper per kg diet 30 mg, iron 20 mg, 10 mg Zn can improve the wool yield 27%, the addition of sodium sulfate 0.2%, stimulate the gastrointestinal mucosa, content may play a role in stomach some can also supplement of elemental sulfur in the feed. Feeding beer: beer lees is rich in vitamins and a large number of bacterial protein, in rabbits fed diets with 40% fresh beer lees can obviously improve the yield of wool, but also decrease the feed cost, improve economic efficiency.

在怀孕19-26天期间,是胎儿毛囊形成的关键阶段,青年母兔自身还要生长和产毛。所以,这一时期的母兔应当给予充足的饲料营养。经验表明,饲料中使用少量鱼粉可以促进幼兔生长,提高毛皮质量。幼兔易患球虫病,可在日粮中添加抗球虫药物预防。

During pregnancy 19-26 days, is a key stage of fetal hair follicle formation, the young mother rabbit itself should growth and wool. Therefore, during this period the female rabbit should be given adequate nutrition. Experience shows that, a small amount of fish meal in feed can promote the growth of young rabbits, improve the quality of fur. Rabbit was susceptible to coccidiosis, adding anticoccidial drug prevention in diet.
