What are the key techniques for efficient fox farming?

1. Vaccinate on schedule and pay attention to drug prevention. Vaccinate twice a year, once in November-December when keeping breeding stock and once in June-July, 3 weeks after the cubs are separated and weaned, using vaccines for canine distemper, viral enteritis, encephalitis, etc., to vaccinate each animal individually, and use the deworming drug Chongkexing to deworm the foxes both internally and externally once.

2. Keep the sheds dry and sanitary. Wash the water bowls and feed bowls frequently, and promptly remove feces and leftover feed from the cages and sheds; regularly spray the ground of the whole site and the cages and sheds with Baidusha solution.

3. Scientific feeding and careful management. Fox feed must be fresh, nutritionally complete and easy to digest. In the daily ration, animal feed is the main component, accounting for about 65%, mainly including small mixed fish, fish meal, poultry and livestock trimmings, etc.; plant feed is supplementary, accounting for about 35%, mainly including corn, @#@245@#@, rice, soybeans, vegetables, etc. At the same time, feed vitamin A, E, B, etc. During the whelping period, the female fox should be given more eggs and dairy foods. In hot seasons, water should be sprinkled on the ground frequently; in winter, the site should be kept warm.

4. Grasp estrus and breed at the right time. Add cod liver oil to the daily ration and feed an appropriate amount of stimulant feeds such as scallions and garlic. From mid-February, regularly carry out estrus checks on the breeding foxes. For female foxes that have already mated, mate them again until the female fox refuses to mate. The key to mating female foxes is "pink is early, purple-black is late, dark red is just right for mating."

5. Patient care to ensure the survival rate. From the first day of mating to 52 days, during this period replace the fox shed with soft, clean dry grass and do a good job of keeping it warm. Decline all visits to prevent miscarriage. When feeding every day, observe carefully; if the female fox carries the cub in her mouth, separate them promptly or give drug treatment. For the few cubs without mother's milk, they must be moved out of the nest box promptly and raised artificially or fostered by another female fox.
