Four grasping methods of raising foxes scientifically

Foxes have high economic value. Its main product is fox skin, which belongs to large capillar. it has the advantages of tough and wear-resistant, soft and lightweight, thermal insulation and beautiful appearance. It is a high-quality raw material for making fur products such as leather collar, cap, leather mattress and so on. How to raise it reasonably and make it create higher value should pay attention to the following points:

(-) pay attention to the breeding of fine varieties. With the improvement of people's aesthetic point of view and the change of the international fur market, the following two points are used as the "reference" in fox breeding as far as possible. General direction:

(1) choose blue foxes or colored foxes with small size, fast growth, good leather, strong disease resistance and multi-color fur to meet the needs of the market for complete designs and colors of fox skins. (2) choose foxes with large size, high reproduction rate, good breeding, bright coat color and excellent fluff varieties to adapt to the changeful market. The remaining foxes should be selected once a year, leaving good breeds, leaving no parental breeds, eliminating inferior ones, and ensuring the purity and quality of foxes.

(2) timely breeding should be grasped. Fox mating period is only once a year, the time is relatively strong, the wrong time will be empty. At ordinary times, we should observe carefully, grasp the characteristics of the sexual cycle changes of male and female foxes, strictly control the oestrus of female foxes, breed them timely and accurately, and work out a reasonable plan according to the individual breeding ability and characteristics of male foxes. In the right time, the fox farm environment should be quiet, and the male fox should be fed with nutritious animal feed to ensure the healthy body condition and good semen quality of the male fox.

(3) rational feeding should be grasped. According to the biological characteristics of fox breeding and hair changing in season, the whole year can be divided into 8 different feeding periods, such as mating period and pregnancy period, and the feeding management is different in different periods. For example, in the pregnant period of the female fox, the diet should be nutritionally complete, fresh, palatable and properly fed. In the early stage of pregnancy, the calorie of feed for silver fox is 550 Mel 600 kcal, and animal feed accounts for 65% Mel 70%. In the later stage of pregnancy, the calorie of animal feed is 700 KCAL, and animal feed accounts for 70% Mel 75%. Each animal rations is 600 Mel 700 grams per day. The arctic fox is 700Mel 850 kcal, animal feed accounts for 70% MUE 75%, and the mouthful is 700MUR 800g per animal. If the feeding is improper, it will cause the fetus to be absorbed, resulting in stillbirth, bad fetus, abortion and other pregnancy phenomena.

(4) the three major infectious diseases of epidemic prevention and sterilization, canine distemper, viral enteritis and viral encephalitis, can be said to be the "nemesis" that affect the normal growth of foxes. In addition, common diseases such as gastroenteritis, colds and pneumonia that foxes are prone to bring certain economic losses to the fox industry. In view of these, we should adopt the policy that prevention is more important than treatment, combination of prevention and control, and giving priority to prevention. Strengthen veterinary health and epidemic prevention system, cut off the introduction of external pathogens; strict feed quality inspection, good disease from mouth to customs; pay close attention to the health status of herds, timely detection of diseased animals, timely diagnosis, regular vaccination. At the same time, we should also pay attention to the cleanliness and hygiene of the fox house and disinfect it regularly.
