        長毛兔的養(yǎng)殖今年變得十分的火熱,在長毛兔養(yǎng)殖的過程中,長毛兔的配種繁殖是重中之重。所以在種兔的選擇上我們要上心,挑選一些年輕健康的雄兔。下面小編就給大家分享一下檢查種兔的幾個技巧:
        The breeding of long-haired rabbits has become very hot this year. In the process of raising long-haired rabbits, breeding and breeding of long-haired rabbits is the most important. So in the choice of breeding rabbits, we should pay attention to selecting some young healthy male rabbits. Here are some tips for checking rabbits.
        一抓:用手抓兔頸后的皮,皮板薄而緊的為青年兔,皮板厚實,多為中、老年兔。
        First catch: Grab the skin behind the neck of the rabbit with your hand. The skin of the rabbit is thin and tight. The skin of the rabbit is thick and thick. Most of the rabbits are middle-aged and old.
        二摸:上摸一條線,假如脊梁觸之如算盤球似的粒粒在手,闡明營養(yǎng)不良,是過瘦的表現(xiàn)。假如一摸有兩肉線,這是“雙脊”是過肥的表現(xiàn)。也不合適當(dāng)做種兔。下摸一大片是指摸兔的肚子。母兔是摸乳房看能否對稱和有幾對,另外摸腹部能否柔軟有彈性,有無腫塊等。假如肚子非常松弛這也是發(fā)育不良的表現(xiàn)。
        Second Touch: Touch a line, if the backbone touches an abacus ball like granules in the hand, to clarify malnutrition, is too thin performance. If there are two meat threads at a touch, it is "double ridge" which is a sign of overweight. It is not suitable for breeding rabbits. To touch a large area is to touch the belly of a rabbit. The key point of the female rabbit is to touch the breast to see whether it is symmetrical and has several pairs, and whether the abdomen can be soft and elastic, whether there are masses, etc. If the stomach is very flabby, it is also a sign of dysplasia.

        三扔:扔主要是檢查兔子四肢能否有過殘疾。正常的兔子從一米多高處往下扔,應(yīng)該是四肢平穩(wěn)著地,假如呈現(xiàn)趔趄,劃水等動作都闡明腿有問題。
        Three Throws: Throwing is mainly to check whether the rabbit limbs have been disabled. The normal rabbit throws down from a height of more than one meter. It should be that the limbs are on the ground smoothly. If the rabbit appears to be staggering, the movements such as paddling and so on all clarify that the legs have problems.
        四翻:即把兔子翻過來,四腳朝天檢查外生殖器,和腹部的背毛等,看有無腳癬,炎癥,隱睪等。
        Quadruple: That is, turn the rabbit over, examine the external genitalia and the back hair of the abdomen with four feet facing the sky, to see if there is tinea pedis, inflammation, cryptorchidism, etc.
        五擠:用拇指從直腸部位可向肛門方向慢慢擠壓。如能擠出12粒糞粒,證明消化系統(tǒng)正常。若擠出水狀,證明消化系統(tǒng)有病。
        Five squeezes: Use thumb to squeeze slowly from rectum to anus. If 12 feces can be extruded, the digestive system will be normal. If the water is squeezed out, it proves that the digestive system is diseased.
