Nowadays, blue foxes and silver foxes raised everywhere belong to Arctic fox and silver-black fox breeds. Their foxes are colorful, fluff is dense and thick, needle hair is tall and straight and soft, and the plate is thin and strong, so the leather is expensive and is not known as "soft gold" in the international market.

1. The reproductive characteristics of foxes the effective reproductive years of foxes can reach 6-8 years, and the foxes give birth to one baby a year. Generally, they are in estrus from February to March. The gestation period is 50-60 days (50-58 days for arctic foxes and 50-61 days for silver-black foxes). From May to June, silver foxes give birth to 4 litters and 14 blue foxes. Young foxes can open their eyes for 13-15 days, eat for 20 days, and be weaned for 45 days. young foxes grow rapidly, mature at the age of 9-10 months, and the fur can be sold at the age of 10-12 months.

two。 The setting of the cage should be in the high and dry terrain and ventilation, preferably far away from the residential area. The specifications for breeding foxes and adult fox cages are 1.5 million and 1.5 meters, and for foxes to be born, another litter box with a specification of 0.7 feet, 0.5 feet, and 0.5 meters should be installed. The size of the young fox cage can be designed according to the number of young foxes, usually 3 to 5 in each cage. The lower part of the fox cage is 40 cm high with brick and the upper part is covered with asbestos tiles for shade and rain protection. The food trough and sink are hung below the side wall of the cage, always keep clean drinking water and feed regularly.

The proportion of dietary composition can be referred to as follows: 47% of corn flour, 10% of sorghum, 20% of wheat bran, 20% of soybean cake powder, 1% of salt and 2% of bone meal. The daily feed amount of adult foxes is 400 grams to 500 grams, including 150 grams of meat, 80 grams of grain, 2 grams of salt, 3 grams of bone meal, 3 grams of feed yeast and the rest are vegetables. Adult foxes are fed once a day and young foxes are fed twice a day, appropriately increasing the amount of minerals and vitamins in the stages of mating, pregnancy and lactation.

Management should keep the shed and cage clean and dry, clean regularly, disinfect regularly, and timely inject foxes with canine distemper, viral enteritis and other vaccines.

4. Management of breeding and childbirth period: first, keep a quiet environment and no outsiders are allowed to enter. If the environment is not good, the female fox will bite the baby fox because it is frightened; second, it is necessary to control the fat of the foxes, prevent them from being too fat and thin, and affect the quantity and quality of their offspring. Pay attention to the increase and supplement of protein feed before and during breeding; third, litter should be divided at the right time to feed the young fox in time. Usually young foxes begin to feed around 20 days old, and are raised in separate nests at 45 days old.
