First, the formulation of goals should be based on the specific situation of the rabbit farm, to establish selection targets. It is impossible to face everything. There should be a focus and a phased choice. It is recommended to simplify the procedure by including the female rabbit's body weight, coat density and reproductive performance (combination conception rate, litter size, live births, weaning survival rate, weaning weight) and maternity (grooming rate, nurse performance). As the female rabbit's key selection project; the weight, coat density, breeding fetus rate, the average survival rate of offspring as a key choice for male rabbits. Second, the formation of core group selection is a complex and meticulous work, very strong technical. The purpose of seed selection is to select those rabbits that have a good surface and a good quality. Only good rabbits and good rabbits can produce good offspring. Therefore, the rabbits in the group should be ranked according to their quality, and the best rabbits should be grouped into a core group. At the time of mating, the best female rabbits are mated with the best male rabbits, consciously producing excellent offspring, and selecting from their offspring, that is, selecting superior ones. Third, stage selection in production, generally adopting stage selection method, or stage elimination method. If one rabbit is selected from 100 puppies, it should be eliminated 50% during the weaning period (according to the weaning weight and the weaning survival rate of the pups, all the poorly performing litters are excluded from the selection). , Elimination of 75% (according to coat, growth, feed consumption, and compatriot performance) at 3 months of age, elimination of 95% at 5 months of age (sex development, coat status, and body weight, the selected rabbits continue to observe With the initial allocation, rabbits that are not reserved for production are slaughtered. When they are initially allocated, they are eliminated by 98%. In other words, only 100 weaned puppies only have 2 breeding partners. However, after the offspring, according to the litter and lactation situation, we will eliminate 1 more, so long as this continues, the quality of the rabbit farm will become better and better. Fourth, pay attention to matters 1. Maintain a certain pedigree. For a large and medium-sized rabbit farm, rabbits should be maintained with certain pedigrees or pedigrees so as to avoid adverse consequences caused by inbreeding. 2. Pay attention to blood renewal. For smaller rabbit farms, it is impossible to maintain more families. In order to avoid close relatives, a small amount of excellent male rabbits should be regularly introduced from the surrounding large-scale rabbit farms to update their bloodlines. 3. Comparison with the conditions. Under the same conditions, comparisons can be made to arrive at a correct conclusion. If we look at the body weight and growth and development, if a female rabbit produced eight puppies and all survived weaning, the average weaning weight was 450 g; while the other female rabbit produced three puppies and weaned at the time of weaning. An average of 600 grams. Just looking at the size of weaning weight is not enough because their conditions are inconsistent. 4. Rex rabbits are in the coat, while the coat should focus on several key parts: 1 the triangle with the upper part of the neck combined with the head, 2 feet, mainly the hindlimbs. 3 inner thighs. 4 Belly coat. 5. Keep recording. Design the relevant forms according to the requirements of breeding, strictly follow the requirements and record them in a realistic manner. Without complete records, breeding work cannot be carried out. 6. Regularly summarize and analyze. Record production results in time, and record or analyze records every year or for a certain period of time so that rabbits can be queried in a comprehensive manner according to their scores, or results of different combinations (male and female rabbits mating to produce offspring) can be performed. queue. Through the performance of future generations, identify the advantages and disadvantages of breeding rabbits, according to the advantages and disadvantages of breeding rabbits, determine the whereabouts of their offspring. According to the combination of results, decide the next breeding of each rabbit
