兔的品種類型很多，但長毛兔只是一個較典型品種，即安哥拉兔?，F(xiàn)在各國飼養(yǎng)的長毛免，都是引用安哥拉兔，但在不同的自然氣候和飼養(yǎng)條件下，采用不同的繁殖和選育方法，培育形成了許多品系。德系安哥拉兔該免產(chǎn)于德國，是目前世界上飼養(yǎng)更普遍、產(chǎn)毛量的一個品系。我國自1978年開始引進(jìn)飼養(yǎng)。

主要優(yōu)缺點(diǎn)
Main advantages and disadvantages
德系兔的主要優(yōu)點(diǎn)是產(chǎn)毛量高，被毛密度大，細(xì)長柔軟，有毛叢結(jié)構(gòu)，排列整齊，不易纏結(jié)。主要缺點(diǎn)是繁殖性能較低，配種比較困難，初產(chǎn)母兔母性較差，少數(shù)有食仔惡癖等。適應(yīng)性較差，公兔有夏季不育現(xiàn)象。
The main advantages of German rabbits are high wool production, high hair density, slender and soft, with hair cluster structure, orderly arrangement and not easy to tangle. The main disadvantages are low reproductive performance, difficult breeding, poor motherhood of primiparous female rabbits, a few vices of feeding young rabbits, etc. The adaptability is poor, and male rabbits have infertility in summer.
