纯种繁育

Purebred breeding

良种兔的纯种育种是指该品种（素）的雄性和雌性兔的配对，使得这个品种的特点可以很好地遗传到下一代，保持了完好的品种的特点，以及生产性能不断改进。必须严格选择纯种繁殖。长毛兔应选择具有良好性状的兔子，如健康，良好的体形和高产量的兔子。科学选择，为后代传递良好品质，不符合标准的不良标准。后代的个体。当长毛兔已形成品种后需要加强词养管理，注意性状的不断巩固和提高。纯种繁育进一步定句繁育种群，品种内部建立品系、品族，防止生活力衰退，并随时发现和淘汰不同性状的手代。

The purebred breeding of high-quality rabbits refers to the pairing of male and female rabbits of this breed (element), so that the characteristics of this breed can be well inherited to the next generation, maintaining the characteristics of the intact breed, and continuously improving production performance. Strict selection of purebred reproduction is necessary. Long haired rabbits should choose rabbits with good traits, such as health, good physique, and high yield. Scientific selection, passing on good qualities to future generations, and eliminating substandard standards. Individual offspring. After the long haired rabbit has formed a variety, it is necessary to strengthen the management of breeding and pay attention to the continuous consolidation and improvement of its traits. Pure breed breeding further determines the breeding population, establishes strains and lineages within the variety to prevent decline in vitality, and constantly discovers and eliminates hand generations with different excellent traits.

所谓的“品系”是指来自该品种中同一祖先的后商群。这组后商不仅具有良好的一般特征，而且在一个或几个特征中脱颖而出。他们之间保持着某种亲缘关系，同时他们之间的关系是相似的。该系的育种是指使用各种方法培育该系。

The so-called "lineage" refers to the later Shang group from the same ancestor in the variety. This group of post quotients not only has good general characteristics, but also stands out among one or several features. They maintain a certain kinship relationship, and their relationship is similar. The breeding of this line refers to the use of various methods to cultivate it.

用这种方法来降低近亲程度，经济效果好。品系繁育选出特别突出、的雄兔，对该雄兔的遗传性能、繁殖力、生产性能进行详细鉴定，证明是的雄兔把它定为原祖。用这种雄兔与的雌兔配对，培育出一群具有原祖优点的个体，并具有一定数量即可称为一个晶系。如从国外引进了的德系的兔子，用雄的德系的兔子与雌的德系的兔子配对，不断扩大德系的兔子种群。不要与其他品种的兔配种，以免造成血统混乱，生产性能不稳定。

Using this method to reduce the degree of kinship has a good economic effect. The first step in breed breeding is to select a particularly outstanding male rabbit, and to conduct a detailed identification of its genetic performance, reproductive ability, and production performance, proving that the male rabbit is designated as its ancestor. Pairing this type of male rabbit with excellent female rabbits to cultivate a group of individuals with ancestral advantages and a certain number can be called a crystal system. If excellent German rabbits are introduced from abroad, male German rabbits are paired with female German rabbits to continuously expand the population of German rabbits. Do not breed rabbits with other breeds to avoid confusion in bloodline and unstable production performance.

杂交繁育

Hybrid breeding

杂交是指不同品系的长毛兔之间的配对，通过用不同的品种进行杂交来获得种后代生产性能高的杂种免群，可降低生产成本，提高利润，长毛兔杂交一代有很强的杂交优势，成活率高，成长快。有目的地从远方兔场引进健康种兔，与本场兔杂交；或利用不同品种兔杂交繁育。长毛兔生产中，长毛兔杂交方式有以下三种。

Hybridization refers to the pairing of different strains of long haired rabbits to obtain hybrid offspring with high production performance through hybridization with different varieties, which can reduce production costs and increase profits. The hybrid generation of long haired rabbits has strong hybridization advantages, high survival rate, and fast growth. Purposefully introducing healthy breeding rabbits from distant rabbit farms and crossbreeding with local rabbits; Or cross breed rabbits of different breeds. There are three hybridization methods for producing long haired rabbits.

（1）改良杂交 某一品种长毛兔与另一品种长毛兔之间条交，目的是使某一品种在保持原有品种特性基础上再吸收另品种的性状，从而提高其种兔的产毛量和品质。例如，饲养的本地毛兔产毛性能较差，直接影响饲养的经济利益，为T迅速改变本地毛兔的这种状况，用本地毛兔作雌本，从外地透用良种雄兔作为父本进行杂交，使之产生产毛性能好的杂种后代，例如用中系的兔子为雌本，与德系的兔子杂交，杂种一代的年产毛量为400~500克，大大超过了纯种中系的兔子的产毛量。

(1) The purpose of improving the crossbreeding between a certain breed of long haired rabbit and another breed of long haired rabbit is to enable one breed to absorb the characteristics of another breed while maintaining the original breed characteristics, thereby improving the wool production and quality of its breeding rabbits. For example, the poor wool production performance of locally bred rabbits directly affects the economic benefits of breeding. In order to quickly change the situation of local rabbits, local rabbits are used as female parents, and high-quality male rabbits from other regions are used as male parents for hybridization to produce hybrid offspring with good wool production performance. For example, using Chinese rabbits as female parents and crossing with German rabbits, the annual wool production of the hybrid generation is 400-500 grams, Greatly exceeding the wool production of purebred Chinese rabbits.

（2）育成杂交 就是把两只兔子或两只以上的兔子品种去进行杂交，一个兔种必然具有若干品质，例如要产毛性能，就型然要在体格、毛密度、毛的生长速度及其他各品质上表现，面实际上不可能每只种免都使这么多品质保持在水平上。为了保持该免种的这些性状，就必须选择具有不同特性的种兔，譬如某兔的毛密度性能特别，另一种免的毛品质特别，以它们为基础建立成各个晶系，以后通过品系间的杂交使后代兼备这几个品系的特点。因为品系间的亲撑茶一般远，所以通过晶系间兔子的配对也可避免不恰当的近交如法国戴葆斯选用了灰色野兔、喜马拉雅兔和蓝色兔作为豪本箱 于1913年育成青紫蓝兔，使其兔皮毛具有独特的青紫蓝色彩，深受消费者青睐。如今在国内培育粗毛型长毛兔的过程中，也应用过这种杂交的手段。

(2) Breeding crossbreeding is the process of crossbreeding two or more rabbit breeds. Each rabbit breed must possess several qualities, such as the ability to produce wool, which must be reflected in its physique, wool density, wool growth rate, and other qualities. In fact, it is impossible for each breed to maintain such many qualities at a level. In order to maintain these traits of the breed, it is necessary to choose rabbits with different characteristics. For example, one rabbit has a special wool density performance, while the other breed has a special wool quality. Based on them, various crystal lines are established, and future generations can combine the characteristics of these strains through hybridization between strains. Due to the fact that the affinity between different strains of tea is generally far apart, improper inbreeding can also be avoided through the pairing of rabbits between crystal lines. For example, France's Deborah chose gray wild rabbits, Himalayan rabbits, and blue rabbits as luxury boxes and bred them into blue and purple rabbits in 1913, giving their fur a unique blue and purple color, which is highly favored by consumers. Nowadays, this hybridization method has also been used in the cultivation of coarse haired rabbits in China.
