Rex is the world famous rabbit skin; in 1919 the individual mutations produced by the French rabbit litter in breeding from. Because of its dense body bright silky hair, smooth appearance, flexible, easy to fall off, can be comparable with the otter, it is our country also known as Rabbit. While the economic value of Rex's high, but if feeding mismanagement, the same can not get desired results, the following should be noted Tatuyangzhi briefly on several key technical issues. First, understand the habits. Because Rex is mutated from the ordinary rabbit, its basic biological characteristics and rabbit no essential difference. For example: timid fear frightened night to go; hi dry, fear of wet; resistant to cold, afraid of hot (optimum temperature is 15 ~ 25 ℃, the critical temperature of 5 ℃ and 30 ℃); hi clean, dirty fear; hi Vegetarian (grazing), tired of meat or fish; homosexual aggressive; love bite, love holes like. Compared with the rabbit, more fragile, poor disease resistance, susceptible to rhinitis, enteritis and other diseases, a slower growth rate, the smaller, longer breeding cycle, higher nutritional requirements, not suitable for extensive breeding; Rabbit It is a mutant trait in the coat, hair, and other traits susceptible to mutation and degradation, but also need to strengthen the breeding. Rex for raising a good understanding of these is essential. Second, the breeding of improved varieties. China is the world's largest countries, raising the amount of Rex, Rex sources descent but mainly the United States, Germany and France. Known as the United States, Ashkenazi and customary law. In principle they are the same species with different crystal groups. Since the incubation conditions and in a different direction, these three lines have their own characteristics. For example, the US Department of rabbit adaptability, disease resistance and productivity up, but smaller, individual differences; Ashkenazi rabbit large size, fast growth, adaptability and productivity but badly; both US law rabbit Advantages and German, but the introduction of the shortest, the introduction of a small number of breeding and adaptation need to be strengthened exercise. For breeders concerned, since Rex expensive in fur, therefore, there is no need to insist that the crystal system, as long as the production of good skin is a good Rabbit. It must be emphasized usual breeding, good seed breeding offspring are not always good, and only good in selected, selecting the best, persevere, after five consecutive generations will be produced outstanding groups. Note hair density, hair smoothness, hair length when breeding; early growth rate, feed conversion; resistance to disease, litter size, lactation and motherhood and the like. To establish a complete pedigree files, breeding work carried out under the guidance of experts.
