First, choose hybrid varieties. Fertilizing with a hybrid of two different breeds of female and male rabbits can significantly increase weight gain. When selecting a crossbreeding combination, it is required that the male parent breed has a rapid weight gain, a high slaughter rate and a high feed conversion rate, and the mother breed has more litters and is more breast-feeding. Second, determine the fattening period. Young rabbits usually start fattening after weaning, and are slaughtered at 3-3.5 months and weighing 2.5 kg. During fattening, if a sudden decrease in the intake of rabbits is detected, indicating that the rabbit is fattening, it should be sold immediately. Third, the male rabbit castration. Castration is beneficial for male rabbits to accumulate fat, reduce feed consumption, and increase the fattening rate by 15%. Castration time is 56-70 days after the male rabbit is born. Commonly used methods of castration are surgical resection and ligation. Surgical resection of the operation: First, the male rabbit is placed on the stool with the abdomen face up, and the limbs are fixed with a rope. The left hand squeezes the testicles from the abdomen into the scrotum and squeezes tightly to make the testicles unable to slide. Disinfect the scrotum with alcohol and use a scalpel. The scrotum was cut open 1 hole, the testis was extruded, the spermatic cord was cut, the testes were removed, the incisions were sewn with threads, and the incision was made with iodine. Operation with ligation method: Fix the male rabbit according to the above method, hold the testicle with one hand, and hold the thick line or rubber band in the Other hand. Wrap the upper part of the testicle with the scrotum neck for several rounds. Fourth, limit sports. Fertilizer rabbits should not be stocked. According to the principles of male and female groupings, strong and weak groups, and nesting groups, cages should be reared in groups of 6-8 rabbits per square meter. Fifth, careful management. First, the feed for fattening rabbits is mainly concentrated, including corn, wheat bran, soybean, sweet potato, sugar beet, bean dregs, and peanut cake. The more reasonable formula: corn 23.5%, barley 11%, wheat bran 5%, bean cake 10%, hay powder 50%, salt 0.3%, vitamins and trace elements 0.2%. Feeding should be regularly ration, plus night food, feeding 3-4 times a day, the proportion of feeding the whole day: 30% in the morning, 20% at noon, 50% at night. Feeding 50 grams per day for the first week of start of fattening gradually increases to 100-200 grams later. Second, drinking water must be sufficient, increase the amount of water in the summer and add baking soda or vitamin C to prevent the heat to cool; winter is cold, supply warm water. The third is prevention. Before inducing the fertilizer, the insects are to be dewormed and vaccinated. The insecticide is fed with 10 mg/kg body weight to albendazole and inoculated with 1 ml of the rabbit aphid-P.
