In recent years, we have successfully explored the 90-day fast fattening rabbit technique. After each batch of rabbits is born, they need to feed for 90 days. The average slaughter weight can reach 2.5 kg, the breeding cycle can be greatly shortened, and the economic benefits can be significantly improved. This technical point is introduced as follows: First, choose to feed breeder rabbits can be directly selected to feed faster Saibei rabbits, Yipulu rabbits, white rabbits, New Zealand rabbits, California rabbits and other large and medium-sized seed. If conditions permit, it is better to use the above-mentioned hybrid male rabbits and native mothers to perform cross breeding, so that the resulting rabbits have more obvious growth advantages. Second, we should do a good job of weaning the transitional weaning, strengthen the female rabbits' nutrition, increase their lactation capacity, and grasp the early feed supplements to avoid early, ensure that the weaned rabbits' weaning weight reaches more than 500 g in 30 days. In this way, weight gain is fast after weaning, and it is also easy to resist weaning stress. Weaning is best done with the method of removing mothers, that is, puppies are still kept in the original cage. If the cage is tight, you need to change the cage, and at least do not separate from the litter. Fattening should be implemented in a small group of cages, not a rabbit or a cage, and it is even more important not to divide flocks and ages to implement a large group of polycultures. This can cause puppies to feel loneliness, alienation, and even fear. After weaning, the feed before weaning should be fed within 1-2 weeks, and then it gradually transitions to fertilization. Otherwise, suddenly change the feed, digestive diseases will appear 2-3 days. Third, the implementation of straight fattening Because the meat rabbits fattening period is very short, from weaning (30 days) to slaughter only about 60 days. Therefore, in the past, the conventional fattening method of filling the loquats in the countryside before the hanging shelves was implemented, and a “one bamboo shoot†linear fattening was carried out. After weaning, the young rabbits no longer feed on green feed and roughage, and should maintain a high level of nutrition to ensure the fast growing nutritional needs of young rabbits. Specific reference can be made to the following formula: 12% of animal protein (fish meal, meat and bone meal, silkworm cocoon, fly maggot, etc.), vegetable protein (bean cake, peanut cake, rapeseed cake, beans, etc.) 13%, energy feed (barley, 58% for corn, millet, sorghum, etc., 11% for succulent green feed, 5% for crude fiber feed (various leaves, hay, etc.) and l% for additives. In terms of feeding methods, it is best to eat freely. As long as the feed ratio is reasonable, let the rabbits freely feed on drinking water, so as not to cause rabbit indigestion, which is better than the traditional method. Fourth, the proper use of additives in addition to meet the fattening rabbit in energy, protein, fiber and other major nutritional needs, but also appropriate use of additives. Such as rare earth additives have the effect of improving weight gain and feed utilization efficiency; olaquindox has the function of promoting protein synthesis and preventing diseases; humic acid additives can improve the production performance of meat rabbits; multiple enzyme preparations can help digestion and improve feed utilization; vitamins, Trace elements and amino acid additives can play a decisive role in improving the fattening effect. The total amount of the above additives is preferably controlled at about 1% of the feed amount. Fifth, to create a good environmental fattening effect, to a large extent, depends on the temperature, humidity, density, ventilation and light and many other environmental conditions. Humidity is 25°C, humidity is 55%-65% and density is based on temperature and ventilation conditions. Under good ventilation conditions, 15-18 rabbits can be raised per square meter of cage. During the fattening period, low light or darkness is applied. Only rabbits can see feeding and drinking water, and they have the effects of inhibiting gonadal development, promoting growth, reducing activities, and avoiding rabbit bites. Sixth, timely slaughter The slaughter slaughter time depends on the species, season and weight. Under normal circumstances, when the meat rabbit reaches a weight of 2.5 kg at 90 days, it can be slaughtered. Large varieties such as Saibei rabbits, Yipulu rabbits, Harbin white rabbits and other slaughter weight of about 3 kg is appropriate. Medium-sized breeds such as New Zealand rabbits and California rabbits weigh about 2.25 kilograms. In winter, the temperature is low and the energy consumption is high. Try to shorten the fattening period as long as the slaughter minimum weight is achieved. In other seasons, the feed is adequate, the temperature is suitable, and the fattening benefit is high. The slaughter weight can be appropriately increased.
