First, the use of optimized hybrid combination technology
One is to pay attention to the selection 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.
Second, we must do a good job early rabbit weight gain
The differentiation of rabbit hair follicles is proportional to the increase in body weight. That is, the greater the body weight, the greater the density of hair follicles. Because the differentiation of hair follicles is mainly in the early stage, weight gain of weaned young rabbits should be grasped. The long-term production practice has proved that unrelenting growth of Rex rabbits before 3 months of age is very effective for improving the quality of commercial rex rabbit coats, rex rabbit body weight and skin area.
Third, take before the promotion of post-control measures
From the time of weaning to 3 months of age or 3.5 months of age, Rex rabbits must pay attention to ensure the nutrition level of Rex rabbits and allow the Rex rabbits to feed freely. It is necessary to make full use of its early growth and development characteristics and to explore its growth. The genetic potential allows young rabbits to eat more quickly. After that, the growth rate should be properly controlled. There are two general methods for controlling the growth rate: one is the quality control method, and the other is the control method. The fattening technology that promotes the post-control can not only save feed but also reduce the cost of feeding. It can also make the fattening rabbits have good skin quality and there will be no excess fat and connective tissue under the skin.
Fourth, the male rabbit should be timely
The male rabbit's castration time is usually selected between 2.5 and 3 months of age.
Fifth, feeding full-priced feed, feeding scientific
During the fattening period of Rex rabbits, feed additives should be used in addition to meeting the needs of its major nutrients such as energy, protein, and cellulose. Such as rare earth elements, humic acid additives, antioxidants, enzyme preparations, probiotics, etc., they have a certain effect on the healthy growth of rabbits and the improvement of the quality of skin. In order to produce the ideal rex rabbit skin, feed nutrition is the key factor, so it is best to feed full-grain pellet feed.
Six, provide a suitable living environment
The temperature of the rabbithouse is preferably kept at about 25°C; the humidity can be controlled at 55%-65%; the density of the stocks in the house should not be too high in general, and small groups should be raised to keep the coat clean and bright.
Seventh, timely slaughter
Normally, when the rabbit is 5 months old and the body weight reaches 2.5-3kg, it can be slaughtered. The elimination of reserved rabbits or rabbits should be avoided in the months of March-April in spring and September-November in autumn, and it is best to eliminate them in winter.
