China's rex rabbit breeding industry has been several times, one important reason is that the lack of scientific management techniques in breeding, promiscuity to mix and match, leading to serious degradation of the species, the quality of rabbit skin decline. In addition, some people have irresponsibly sold rabbits because of their interest, which has exacerbated the degeneration of rabbit breeds. Another problem is: "reintroduction, light breeding, heavy quantity, light quality, heavy rabbit species, light breeding management." Many farmers only consider reducing the cost of feed, resulting in degradation of the variety. Today Xiaobian introduced the optimized hybrid combination technology for everyone.
First, attention should be paid to the selection and breeding of excellent rabbit species to breed a large number of excellent offspring to produce high-quality hides. The second is to adopt inter-system hybridization. Currently, domestic rex rabbits are mainly American, German and legal systems. From the perspective of fertility, the U.S. rabbits have the highest scores and the Germans have the lowest scores. From the point of view of the growth rate, the German rabbits have the greatest growth potential. You can use American rabbits as the first generation female parent and German or French rabbits as the first generation male parent to crossbreed; then use the hybrid female rabbit as the second generation female parent, and the second generation parent female German Rex rabbits were crossed and the offspring of three-way hybrids were used for direct fattening. The mass production practice has proved that its production effect is better than that of purebred rex rabbits.
