First, the fattening rabbit rabbit source and selection of rabbits used for fattening is a young rabbit dedicated to fattening, and the other is out of young rabbits. 1. Young rabbits used for fattening young rabbits can be purebred meat rabbits or both hybrids. They can also be hybrid rabbits. In countries where meat rabbits are developed, special hybrids are used for fattening. 2. Obsolete young rabbits Young rabbits with poor performance after short-term breeding can be eliminated. Elimination of rabbits depends on the decision whether to fatten. For the elimination of manure, rabbits can be stopped breeding, and they can be directly marketed for a certain period of time. Excessively sensible breeds do not have to be fattened again. Due to longer time for fattening, more feed is consumed, and economic efficiency is not high, they can be directly listed or used. Other animal feeds; Moderately mild conditions, listed after short-term (a month or so) fast fattening. Second, fattening rabbit growth and development rules and feed compensation Rabbits grow rapidly. New Zealand white rabbits, for example, are only about 50 grams at birth, up to 450 grams at 3 weeks of age, and have an average daily weight gain of about 20 grams. They begin to eat solid feeds at 3 weeks of age and grow daily at 3-8 weeks of age. Weight up to 30-50 grams; after 8 weeks of age, the growth rate began to decline; 10-12 weeks of age, the growth rate slows. The law of growth, with the increase of age and body weight, weight gain rate from fast and slow until stagnation. From the point of view of feed utilization, as the body weight increases, the feed required per unit body weight increases accordingly. At 3 weeks of age, the feed conversion rate was 2:1; at 8 weeks of age it was reduced to 3:1; at 10 weeks of age, it was about 4:1; at 12 weeks of age, it fell to 5:1. Third, the fattening and fattening of meat rabbits starts from two aspects. On the one hand, it tries to make the fat accumulation in the fattening rabbits, and on the other hand, it can reduce the nutrient consumption in the body as much as possible. During the fattening period, in addition to scientific breeding, we must also limit the fattening of rabbits, control the light (about 8 hours of light per day), and keep the house quiet, which is conducive to fattening and improving the quality of rabbit meat. 1. Influencing factors (1) The varieties of meat are better than those of the combined varieties; the hybrids are better than the pure breeds; the specialized breeds of hybrid offspring have the best fattening effect. However, in the production, it is necessary to select suitable varieties for fattening according to the rearing level and technical conditions. If conditions are not met, it is not necessary to use good breeds. Otherwise, things will be counterproductive. (2) Feeding methods Feeding fattening rabbits by free-feeding methods has a better fattening effect than limited feeding (timed ration). (3) The effect of finishing feeds with full-price compounded feeds tends to be better than mixed feeds and better than single feeds. The composition of finishing feeds should be at least 3 or more, and the proportion of raw materials should be determined according to the feeding standards. (4) The optimal temperature for temperature and light is 5°C-25°C. Exceeding this range affects the fattening effect. The daily light time does not exceed 10 hours, and the light is dark, which is conducive to fattening. 2, fattening technology (1) There are two feed types for finishing feeds, one is full-priced pellets, and the other is “green roughage + concentrate supplementsâ€. Feed composition should be relatively stable and should not be changed easily. (2) Feeding methods Regardless of the feed, free-feeding is used. In this way, the meat rabbits gain weight quickly and have high feed rewards. Fourth, timely listing of meat rabbits listed on time, is to improve the economic benefits of meat rabbit production an important part. From the point of view of the growth and development of meat rabbits, from birth to 10 weeks of age, with the growth of age, weight increased linearly, after which the growth rate significantly slowed. Over 10 weeks of age, feed utilization has decreased significantly. When meat rabbits are on the market, they are very demanding. Before 10 weeks of age, although the feed utilization rate is high, the body weight is small and the slaughter rate is low; after 13 weeks of age, it is listed, the body weight is larger, the slaughter rate is higher, but the feeding period is longer and the economy is longer. The efficiency is not high. The appropriate time to market is that the rearing period is no more than 13 weeks and the weight is not less than 2.5 kg. At present, meat-rabbit-developed countries are raised under intensive conditions, are 11-week-old and weigh 2.5 to 2.7 kilograms, which are listed on the market and reach the same weight. Under the general conditions in China, they are 13 to 15 weeks old or longer.
