Breeding rabbits have a lot of "pairing" skills

On the basis of strict seed selection, artificial control of the rabbit's spouse is what fashion calls "pairing," but the terminology is called "matching." The main purpose of the matching is to provide excellent individuals with more opportunities for mating and better recombination of good genes to increase the homogeneity of the rabbit population and to promote the improvement and improvement of the rabbit population. This is a regular rabbit farm. Non-negligible work. So how do you do it?

1, a variety of methods, different from rabbit

The first is that homogenous matching is to select excellent male and female rabbits with the same traits, consistent performance, or similar breeding value for breeding, in order to obtain similar excellent offspring. The more similar the matching parties are, the more likely it is that the common good quality be passed on to future generations to maintain and consolidate the good traits. For example, choosing the large size, good quality fur and female rabbits for mating, can further stabilize and consolidate the genetic properties of the importance of the weight and fur quality of rabbits.

The second kind is heterogenous matching. It can be divided into two cases. The first is to select male and female rabbits with different superior traits to match each other in order to combine the two traits together, so as to obtain offspring with different advantages of both parents. For example, selecting a long-haired and hairy rabbit matches the purpose. Another example is that selecting medium-sized rabbits with high hair density and matching the rabbits with large hair density but with a large body size brings together fine hairy and large-sized traits that can improve fur quality in offspring. The second is to select the male and female rabbits with the same traits but with different degrees of good or bad to match each other, with good and bad, with good and bad, with good traits to correct the bad traits, so that future generations can achieve greater improvement and improvement. For example, some rex rabbits are thin and evenly distributed, while others are hairy but poorly homogenous. After mating by heterogeneity, hairy and even-looking offspring can be obtained.

The third type is the age-matching and suitable mode of adoption: young male bunnard prime female rabbit; excellent old male female first-year female rabbit; young male male mature female rabbit; young male rabbit female female;

The fourth type is kin choice matching, also known as pro-community, which is an abbreviation for close-parent mating or kinship mating. It refers to the mutual mating of the parents to the common ancestor's total generation of no more than six generations. This method is mostly used in rabbit breeding. Inbreeding is prone to decline, such as decreased offspring resistance and viability, offspring mortality during embryonic or postnatal periods, appearance of malformed rabbits, slow growth, and reduced fertility and productivity. Use less on rabbits.

2. Basic principles must be observed

The goal is to clearly select and match the selection of the species. It must focus on the overall objectives of breeding and production services, and avoid blindness and "one size fits all."

Inbreeding should be controlled in the breeding of rabbits. In pursuit of fixed and good traits, exposing harmful genes, maintaining good pedigrees, and improving the homogeneity of rabbit populations, sometimes inbreeding has to be adopted, but in rabbit breeding and commercial rabbit production Not promoted. Generally, it is necessary to master 5 to 7 unrelated rabbits to be paired, especially the father and the female, the mother and the son, and the siblings must not be mated. When encountering the above-mentioned troubles in breeding, it is necessary to prevent it by strengthening the breeding program, strict selection system, and strengthening the feeding and management of the inbreds. Among them, "blood renewal" is more valuable. The specific method is to replace the siblings or female rabbits of the same type but unrelated breeds from the brother rabbit farm for blood renewal. The key is to pay attention to the introduction of rabbits with similar characteristics so as not to offset the inbreeding Effect.

The main points of matching must be that: All age and weight do not meet the standards of non-participation; excellent female rabbits must be mated with excellent male rabbits, that is, male rabbits of higher quality than female rabbits; old rabbits and old rabbits, young Rabbits and young rabbits cannot be matched. Old rabbits do not work well with young rabbits. Only the mating male and female rabbits or young female rabbits, old female rabbits, and young male rabbits can achieve better results. Female rabbits do not match (such as dorsum rabbits and rabbits, rabbits and hairy rabbits can not be matched), genetically defective rabbits (such as bull's eye, monotesticle, dog legs, etc.) can not participate in breeding and so on.

Note that when the affinity of the male and female rabbits selected by the affinities is combined to produce offspring, there is still a problem of mutual interaction. Sometimes it is compliant, and sometimes it fails to do so. Therefore, it must be carefully observed. If they have poor post-natal representations (such as fewer litters, weaker viability, and poorer disease resistance), they should not be combined until the next breeding match.
