種質(zhì)和飼養(yǎng)是決定任何動物生長發(fā)育和生產(chǎn)性能的兩個更重要的因素，也是影響毛用兔產(chǎn)毛性能的兩個更重要的因素，所以設(shè)計長毛兔飼料配方時也應(yīng)當(dāng)以飼養(yǎng)標(biāo)準(zhǔn)為依據(jù)。在長毛兔的配合飼料中，更重要的養(yǎng)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%，而一般配合日糧中含硫氨基酸不能滿足高產(chǎn)毛的需要，因此在日糧中加人0.7%的蛋氨酸可提高產(chǎn)毛量20%。全價配合飼料中個別微量元素仍不能滿足兔高產(chǎn)毛的需求，所以在日糧中加人適量的銅、鐵、鋅可促進角質(zhì)化蛋白的生成，提高產(chǎn)毛量。據(jù)研究，在每公斤日糧中添加銅30毫克、鐵20毫克、鋅10毫克可提高產(chǎn)毛量27%，另外添加硫酸鈉0.2%，刺激胃腸粘膜，可起到一定的健胃作用并能補充飼料中的硫元素的含量。飼喂啤酒糟:啤酒糟中富含維生素和大量菌體蛋白，在兔日糧中加人40%鮮啤酒糟可明顯提高產(chǎn)毛量，還可降低飼養(yǎng)成本，提高經(jīng)濟效益。
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.
在懷孕19-26天期間，是胎兒毛囊形成的關(guān)鍵階段，青年母兔自身還要生長和產(chǎn)毛。所以，這一時期的母兔應(yīng)當(dāng)給予充足的飼料營養(yǎng)。經(jīng)驗表明，飼料中使用少量魚粉可以促進幼兔生長，提高毛皮質(zhì)量。幼兔易患球蟲病，可在日糧中添加抗球蟲藥物預(yù)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.
