表型选配

Phenotypic selection

表型选配又称为品质选配，是根据外表性状或品质选择配公母兔的一种方法。它又可以分为同型选配和异型选配两种。

Phenotypic selection, also known as quality matching, is a method of selecting a female rabbit based on apparent traits or qualities. It can be divided into two types: the same type selection and the odd type selection.

同型选配

positive assortative mating

同型选配就是选择性状相同、性能表现一致的公母兔配种，以期获得相似的后代。选配双方愈相似，愈有可能将共同的品质传给后代。其目的在于使这些性状在后代中得到保持和巩固，也有可能把个体品质转化为群体的品质，使个体数量增加。例如，为了提高兔群的生长速度，可选择生长速度快的公母兔交配，使它们的后代保持这一特性。因此，这种选配方法适用于公母兔之间。

The same type selection is to select the same nature and performance of the same male and female rabbit breeding, in order to obtain similar good offspring. The more similar they are, the more likely it is to pass on the same good qualities to their offspring. The aim is to maintain and consolidate these fine traits in future generations, and to transform individual qualities into group qualities and to increase the number of good individuals. For example, in order to increase the growth rate of rabbit populations, male female rabbits with fast growth rate can be chosen to mate with their offspring to maintain this fine trait. Therefore, this method is suitable for excellent male and female rabbits.

异型选配

negative assortative mating

异型选配可分为两种情况，一种是选择有不同优异性状的公母兔交配，以期将两个性状结合在一起，从而获得兼有双亲不同优点的后代。例如，选择兔毛生长速度快和兔毛密度大的公母兔交配，从而使后代兔毛生长速度快和兔毛密度大，更终使后代产毛量提高。

There are two types of special selection. One is to choose the male and female rabbits with different excellent traits, in order to combine the two characters, so as to obtain offspring with different parents' advantages. For example, choose the hair growth speed and rabbit density of the male and female rabbits mated to offspring hair growth speed and hair density, the offspring of wool yield increase.

另一种情况是选择同一性状优劣程度不同的公母兔交配，即所谓以优改劣，以性状纠正不良性状。例如在本品种中，有些肉用种兔繁殖性能较好，只是生长速度较慢，即可选择一只生长速度快的肉用公兔与其相配，使后代不仅繁殖力高而且生长速度也较快。实践证明，这是一种可以用来改良许多性状的行之有效的选配方法。

Another situation is that the male and female rabbits of the same character are chosen to mate with each other, which is called "superior to bad", and good characters are used to correct the bad characters. For example, in this species, some better reproductive performance of meat rabbits, but slower growth rate, you can choose one of the fastest growing meat rabbits matched, so the offspring not only high fecundity and growth rate is faster. Practice has proved that this is a kind of effective selection method that can be used to improve many characters.

年龄选配

Age matching

年龄选配，就是根据公母兔之间的年龄进行选配的一种方法。家兔的年龄明显地影响其繁殖性能。一般青年种兔的繁殖能力较差，随着年龄的增长繁殖性能逐渐提高，1岁～2岁繁殖性能逐渐达到高峰，2岁半以后逐渐下降。在我国饲养管理条件下，种兔一般使用到3岁～4岁。所以在养兔生产实践中，通常主张壮年公兔配壮年母兔，采用这种选配方式效果较好。0..

Age selection is a method of selecting matches according to the age between the male and female rabbits. The age of the rabbit significantly affected its reproductive performance. The general young rabbit breeding ability is poor, with a gradual increase in growth performance of age, 1 years old to 2 years old reproductive performance gradually reached the peak, and decreased gradually after 2 and a half years old. In our country, feeding and management conditions, the general use of rabbits at the age of 3 to 4 years old. Therefore, in the practice of raising rabbits, it is generally advocated that the male rabbits should be matched with the young rabbits. 0..
