純種繁育

Purebred breeding

良種兔的純種育種是指該品種(素)的雄性和雌性兔的配對,使得這個品種的特點可以很好地遺傳到下一代,保持(chí)了完好的品種的特點(diǎn),以及生產性能(néng)不斷改進。必須(xū)嚴格選擇純種繁殖。長毛兔應選擇具有良好性狀的兔子,如健(jiàn)康,良好的體形(xíng)和高產量的兔子。科學選擇,為後代傳遞良好品質,不符合標準的不良標準。後代的個體。當長(zhǎng)毛兔已形成品種後需要加強詞養管理,注意性狀的不斷鞏固和提高。純(chún)種繁育進一步定句繁育種群,品種內部建立品係(xì)、品族,防止生活力衰退,並隨時發現和(hé)淘汰不(bú)同性狀的手代。

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.

所謂的“品係”是指來自該(gāi)品種中同一祖先的後商群。這組後商不僅具有良好(hǎo)的一般特征,而且在一個或幾個特征中脫穎而出。他們之間(jiān)保持著某種(zhǒng)親緣關係,同時(shí)他們之間的(de)關係是相似的。該係的育種是指使用各種方法培育該係。

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.

用這(zhè)種方法來降低近親程度,經濟效果(guǒ)好。品係繁育(yù)選出特別突出、的雄(xióng)兔,對該雄兔的遺傳性能、繁殖力、生產性能進行詳細鑒定,證明是的雄(xióng)兔把它定為原祖。用這種雄兔與的雌兔配對,培育出一群具有原祖優點的個體,並具有一定數量即可稱為(wéi)一個(gè)晶係(xì)。如從國外引進了的德係的兔子,用雄的德(dé)係的兔子與雌的德係的兔子配對,不斷擴大德(dé)係的兔子種(zhǒng)群。不要與其他品種的兔配種,以免造成血統混亂,生產性能不穩定。

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.

雜交繁育

Hybrid breeding

雜交是指不同品係的長毛兔之(zhī)間的配對,通過用不同的品種進(jìn)行雜交來獲得種後代生產性能(néng)高的(de)雜種免群,可降低生產成本,提高(gāo)利潤,長毛兔雜(zá)交一(yī)代有(yǒu)很強的(de)雜交優勢,成(chéng)活率高,成長快。有目的地從遠方兔場引(yǐn)進健康種兔,與本場兔雜(zá)交;或利用不(bú)同品種兔雜交繁育。長毛兔生產中,長毛兔雜交方式有以下三種。

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)改良雜交 某一(yī)品種長毛兔與另一(yī)品種長毛兔之間條交,目的是使某一品種在保持原有品種特性基(jī)礎上再吸收另品種的性狀(zhuàng),從而(ér)提高(gāo)其種兔的產毛量和品質。例如,飼養的本地毛兔(tù)產毛(máo)性能(néng)較差,直接影響飼養的經(jīng)濟利益,為T迅速改變本地毛兔的這種狀況(kuàng),用本地毛兔作雌本,從外地透用良種雄兔作為父本進行雜交,使之產生產毛性(xìng)能好的雜種後代,例如用中係的(de)兔子(zǐ)為雌本,與德係的兔子雜交,雜種(zhǒng)一代的年產毛量為400~500克,大大超過了(le)純種中係的兔子(zǐ)的產毛(máo)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)育成雜交 就是把兩隻兔子或兩隻以上的兔子品種去進行雜交,一個(gè)兔種必然(rán)具有若幹品質,例如要產毛(máo)性能,就型然要在體格、毛密度、毛的生長速度及(jí)其(qí)他各品質上表現(xiàn),麵實際上不可能每隻種免(miǎn)都使這麽多品質保持在水(shuǐ)平上。為了保持該免種的這些(xiē)性狀,就必須選擇具有不同特性的種兔,譬如某兔的(de)毛密度性能特別,另一種免的毛品質特別,以它們為基礎建立成各個晶係,以後通過品係間的雜交使後代兼(jiān)備這幾個品係的特點。因為品係間的親撐茶一般遠,所以通過晶係間兔子的配對也可避免不恰當的近(jìn)交如法國(guó)戴葆斯選用了灰色野兔(tù)、喜馬拉雅兔和藍色兔作為豪本箱 於1913年(nián)育(yù)成青紫(zǐ)藍兔,使其(qí)兔皮毛具有獨(dú)特的青紫藍色彩,深受(shòu)消費者青睞。如今在國內培育粗毛型長毛兔的過程(chéng)中,也應用過(guò)這種雜交的手段。

(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.
