        發布日期:2015-12-04 來源:http://m.jinrimeigu.cn 發布人:admin

          長毛兔,原譯安哥拉兔,起源于小亞細亞一帶,名字來自安哥拉城,即現在的土耳其首都安卡拉。安哥拉兔從1723年由英國海員帶到法國,再傳到世界,后來形成了法、英、德和中四個不同的品系。那今天蒙陰長毛兔廠家就給您介紹一下長毛兔的發展。

          Hares, the original translation of Angora rabbit, originated in Asia minor, city name from Angola, what is now Turkey's capital Ankara. Angora rabbit by British sailors to France in 1723, and then spread to the world, and then formed in the method, Britain, Germany, and four different strain.

          我國的長毛兔品種,多是上世紀80年代引進的德系安哥拉長毛兔、法系安哥拉長毛兔、日系安哥拉長毛兔。我國引進時單只成年長毛兔年產毛量也就不到一公斤的樣子。多年來,經過我國人員和有經驗的養殖戶,采用多品種生物技術雜交、橫交等改良方法,我國浙江、山東、河南等不同地區先后不同程度的提高了長毛兔產毛量,于品種的命名,有條件的大型廠家請有關評定進行了命名,例如:彩色長毛兔、浙江的嵊州“白中”長毛兔、英系安哥拉長毛兔、寧波鎮海巨高長毛兔、中系安哥拉長毛兔,單只成年長毛兔年產毛量超過國外產量,達到1.5公斤到2.5公斤;山東的蒙陰長毛兔產量也已經達到這個產量;有的較小型長毛兔場家由于各種原因,尚沒有給予正式命名,例如河南省虞城縣遠揚長毛兔良種繁育示范點的明哲長毛兔,在家兔教授指導下,同時提速兔毛密度和兔毛生長速度兩種技術并用,2013年春季選出單只成年長毛兔年產毛量超過2.5公斤的繁殖種兔,更高的兩只年產毛量達到3.5公斤。

          Hares varieties in China, is introduced in the 1980 s ashkenazi hares, Japanese Angola Angola hares, law system hares. When introduced into China only adult hares producing wool quantity is less than a kilogram. Over the years, through our professional and experienced farmers, using biotechnology varieties, improved methods of crossing, zhejiang, shandong, henan and other areas in China have different levels of the hares wool quantity production, as for the variety of naming, conditional large manufacturers please experts assess the naming, for example: the color of the hares, zhejiang shengzhou "Bai Zhongwang" hares, YingXi hares, ningbo zhenhai giant high hares, Angola Angola hares, single adult hares producing wool quantity more than foreign production, 1.5 kg to 2.5 kg; Shandong darkened hares production has reached the production; Some smaller hares field due to various reasons, there is no formal name, such as henan yucheng hares thoroughbred breeding demonstration site of one of the hares, wise in rabbit under the guidance of experts and professors, and acceleration of rabbit hair density and rabbit hair growth and two kinds of technology, in the spring of 2013 selected single adult hares annual amount is more than 2.5 kilograms of breeding the plasticine, MAO MAO's highest two year is 3.5 kg.

          隨著人們生活水平的提高和兔毛紡織技術的改進,對兔毛的需求量越來越大,長毛兔養殖具有廣闊的發展前景。特別是2004年以來,兔毛價高且平穩,又進一步激發了長毛兔養殖戶的積極性。作為發展前景

Especially since 2004, the high price of rabbit hair and smooth, and further stimulate the enthusiasm of the hares farmers. As the development prospect of
