        發布日期:2016-12-22 來源:http://www.chle.cn 發布人:admin

        一、公母兔的鑒別方法,主要有如下三點:
        First, the identification method of male and female rabbits, mainly as follows three points:
        初生仔兔:可觀察陰部孔洞形狀和肛門之間的距離,孔洞扁形而略大,與肛門相同,間隔距離較近者為母兔。孔洞圓形而略小于肛門,洞向前方,間隔距離較遠的為公兔。
        Newborn rabbit: can be observed between the anus and genitals hole shape and flat hole distance, slightly larger, and the same distance near the anus, as mother rabbit. Hole round and slightly smaller than the anus, the hole to the front, the distance between the distance for the male rabbit.
        開眼后的仔兔:要檢查生殖器。方法是:用右手抓住仔兔耳頸部,左手以中指及食指夾住兔尾,大拇指輕輕向上推開生殖器,局部呈“O”型,下為圓柱體者為公兔。局部呈“V”型,下端裂縫延肛門者為母兔。
        His eyes after the rabbit: to check the genitals. Method is: the right hand to seize the Aberdeen rabbit ear neck, the left hand to the middle finger and index finger to clamp the rabbit tail, thumb gently push up genitals, local was O type, under the cylinder for the male rabbit. Local was "V" type, the lower crack extension to anal is the mother rabbit.
        幼兔及青年兔:用手打開生殖器,陰部呈圓柱形是公兔。呈尖葉形,裂縫延下方接近肛門的是母兔。
        Young rabbit and young rabbit: opens the genitals with the hand, the perineum assumes the cylinder is the male rabbit. A sharp leaf, crack extension to bottom near the anus is female rabbit.
        二、家兔的去勢,能提高皮、肉、毛的質量,使它性情溫順便于飼養,凡不留種用的公兔,在2.5~3月齡時可作去勢手術。其方法有兩種:
        Two, rabbit castration, can improve the quality of meat, skin, hair, make it easy docile rearing, who is not the seed of male rabbit, in March at the age of 2.5 to be castrated. There are two kinds of methods:
        閹割法:將兔子固定好,腹部朝上。左手將睪丸由腹腔擠入陰囊,并捏緊,不使睪丸滑動,再用酒精在切口處,用過的手術刀將陰囊切一小口,用手擠出睪丸,切斷精索。摘除睪丸后,再一次在切口上涂碘酒。
        Castration method: the rabbit fixed, abdomen up. The left hand will squeeze into the scrotum and testis by intraperitoneal, pinch, do not make testicular sliding, with alcohol disinfection in the incision with a scalpel, sterilized the scrotum cut a small mouth, hand out of the testis, cut the spermatic cord.
