          仔、幼兔培育 重視仔、幼兔的早期管理和選育,使育出的種兔抗病力強、生長快、產毛量高。為使仔兔吃足乳,母兔哺育仔兔以每窩4~5只為宜,出生后18天左右開始吃飼料,逐漸喂給少量易消化而營養高的飼料,如豆漿、牛奶、鮮嫩青草等。
          Early management and breeding should be emphasized in the breeding of young and young rabbits, so that the breeding rabbits have strong disease resistance, fast growth and high wool yield. In order to make the young rabbits eat enough milk, it is appropriate for the female rabbits to feed on 4-5 piglets per litter. They should start to eat feed about 18 days after birth, and gradually feed a small amount of digestible and nutritious feed, such as soybean milk, milk, fresh and tender grass, etc.
          由于仔兔胃容積小、消化力弱,生長發育快,要少喂多餐,開食初期以母乳為主,母乳為輔,30日齡后,則轉變以飼料為主,母乳為輔,直離乳。斷奶后的幼兔可4~5只一籠群養,并在一周內把乳毛全部剪去,以增強血液循環,促進生長發育。同時喂給容易消化、容積小、能量和蛋白質水平高的飼料,要少喂多餐,防止因一次多喂造成腹脹下痢,造成死亡。

          Due to the small gastric volume, weak digestive capacity and rapid growth and development of young rabbits, they should eat less and more meals. At the initial stage of feeding, breast milk is the main supplement. After 30 days of age, they will change to feed mainly, supplemented by breast milk until weaning. After weaning, 4-5 rabbits can be raised in a cage, and the milk wool should be cut off within one week to enhance blood circulation and promote growth and development. At the same time, feed easy to digest, small volume, high energy and protein levels of feed, to feed more than one meal, to prevent abdominal distension and diarrhea, resulting in death.
          粗毛率高的兔作種繁殖。根據粗毛型兔的特點,宜采用同質選配,就是選擇性狀相同或性能表現一致的公母兔來配種,以期獲得相似的后代。以年產仔4胎為例,其中秋配時,因經高溫應激后,粗毛型兔公兔精子尖力恢復較快,故可比一般兔提早10多天進行配種繁殖。選留下一代種兔,則以春季和秋季所產的兔為宜。
          Rabbits with high rate of coarse hair breed. According to the characteristics of coarse wool type rabbits, it is appropriate to adopt homogeneous mating, that is, to select excellent male and female rabbits with the same traits or performance, so as to obtain similar excellent offspring. In autumn mating, the sperm tip strength of male coarse wool rabbit recovered quickly after high temperature stress, so it could be mated more than 10 days earlier than ordinary rabbits. In spring and autumn, the rabbit is the best.
