      長毛兔引種須知

      發布日期:2019-05-14 來源:http://www.xtjjsh.com 發布人:admin

      為了引進長毛兔種類,提高長毛兔的產毛質量,我們有時會進行長毛兔的引種,所以我們廣大養殖戶應該熟知種兔的質量辨別方法。
      In order to introduce high quality long-haired rabbits and improve their wool production quality, we sometimes introduce long-haired rabbits. Therefore, we should be familiar with the quality identification methods of breeding rabbits.
      辨別的長毛種兔,我們可以運用下面四點:一看二聽三摸四吹。
      To distinguish high quality long-haired rabbits, we can use the following four points: one look, two listen, three touch and four blow.
      (一)看長毛外觀,四肢兔毛豐滿,身子呈圓柱形,兩耳豎立,眼睛干凈有神!看毛型粗度,養殖長毛兔適當選用中粗毛型的兔子作種用,既增加了產量又得到群體很好的抗病力,夏季還稍耐熱!
      (1) Look at the appearance of long hair, rabbit hair on all fours is plump, body is cylindrical, ears erect, eyes clean and godly! Looking at the roughness of wool type, breeding long-haired rabbits should choose medium-haired rabbits as seed, which not only increases the yield, but also obtains good disease resistance of the population, and is slightly heat-resistant in summer.
      (二)聽毛兔呼吸是否有喘音或喉音!
      (2) Listen to whether the rabbit breathes with wheezing or laryngeal sounds!
      (三)摸一下背毛與胸毛是否豐厚,正常密度高的種兔摸上去呈一搓一搓的小疙瘩!
      (3) Touch whether the back hair and chest hair are thick or not, and the normal density rabbit feels like a rubbing knot!
      的長毛兔
      (四)吹一下背毛和胸部的毛,使勁吹一下,兔毛很容易展開并看到兔的表皮,這樣的兔子毛密度稀疏;如很難免吹開,并看不到表皮則密度高!
      (4) Blow back hair and chest hair, blow hard, rabbit hair can easily spread out and see the rabbit's skin, such rabbit hair density is sparse; if it is difficult to avoid blowing, and can not see the epidermis, then the density is high!
      有些兔場年年引種,可年年產量上不去,兔子還養不好,兔子抗病不抗病主要還是在兔子的毛襄上,又細又密的毛型這樣的兔子肯定不好養,應激能力差,對飼料要求還要高!
      Some rabbit farms introduce rabbits every year, but the annual output can not go up, rabbits are still not well-fed, rabbits are mainly resistant to disease or disease in the rabbit's hairpin, fine and dense hair type of rabbits must be poor breeding, poor stress ability, feed requirements are also high!
      以上就是關于長毛兔引種時辨別的長毛種兔的方法了,不知道大家明白沒有,如果大家還有疑問歡迎咨詢我們官網的客服人員:http://www.xtjjsh.com
