    如何辨別兔的年齡

    發布日期:2019-06-04 來源:http://www.whxfy.cn 發布人:admin

    兔兔可以活多久,要怎么識別兔兔的年齡呢?而且兔子的年齡也對長毛兔的產毛量有很大的影響,下面小編帶大家了解一下辨別兔子年齡的小方法。
    How long can a rabbit live? How can we identify the age of a rabbit? And the age of rabbits also has a great impact on the wool production of long-haired rabbits. Here are some tips for you to learn how to distinguish the age of rabbits.
    兔的門齒和爪隨年齡增長而增長,這是年齡鑒別的重要標志。青年兔門齒潔白短小,排列整齊;老年兔門齒黃暗,厚而長,排列不整齊,有時破損。紅色家兔趾小基部呈紅色,呈白色。一歲家兔紅色與紅色長度相等;一歲以下,紅多于白,一歲以上,白多于紅。有色的家兔可根據趾爪的長度與彎曲來區別,青年兔較短,直平,隱在腳毛中,隨年齡的增長,趾爪露出腳毛之外,而且爪尖鉤曲。
    Rabbits'incisors and claws increase with age, which is an important sign of age discrimination. The incisors of young rabbits are white, short and neatly arranged; the incisors of old rabbits are yellow and dark, thick and long, irregularly arranged and sometimes damaged. Red rabbit toes are red at the base and white at the tip. One-year-old rabbits have the same length of red and red; under one-year-old rabbits have more red than white, and over one-year-old rabbits have more white than red. Coloured rabbits can be distinguished according to the length and curvature of their toes and claws. Young rabbits are short, flat and hidden in the hairs of their feet. As they grow older, their toes and claws are exposed outside the hairs of their feet, and their tips are crooked.
    長毛兔
    壯年兔(1-3歲)趾爪粗細適中,較平直,逐漸露出腳毛之外,趾爪顏色是紅白相等;門齒白色,粗長而整齊;皮板薄厚適中,結實緊密。
    Adult rabbits (1-3 years old) have moderately thick and straight toe claws, which gradually reveal the same color of red and white, white incisor teeth, thick and neat, and moderately thick and compact skin.
    老年兔(3歲以上)眼神無光,行動愚鈍;趾爪粗而長,爪尖鉤曲,外表精細無光澤,一半露出腳毛之外,紅色多于紅色;門齒呈黃褐色,厚而長,時有破損;皮板厚而松弛,長毛兔被毛出現兩型毛較多。
    Old rabbits (over 3 years old) have dull eyes and dull movements; their toes and claws are thick and long, their tips are crooked, their appearance is fine and dull. Half of the hair exposed on their feet is red more than red; their front teeth are yellowish brown, thick and long, sometimes damaged; their skin is thick and loose, and the fur of long-haired rabbits has more two types of hair.
