Silver Black Fox is Red fox a genetic mutation, belonging to the carnivorous order Canidae, originating from Alaska and eastern Siberia, after more than 100 years of artificial breeding and training, has become a breeding ground for people Major species of precious fur animals. The silver-black fox's coat is black and white, with a layer of fog-like needle hair. It is the main accessory of modern people's winter fur clothing. Silver-black foxes are crossed with blue foxes, silver-black foxes, blue-silver foxes (two foxes commonly known as blue frost foxes), crystal foxes, golden island foxes, agate foxes, etc. The advantages of the red fox are that the needle hair is thin and straight, short and flat, the silver hair is evenly distributed, and the color is gorgeous. It is one of the main high-grade furs on the market.

The silver-white hair segment of the needle hair is relatively thick and long, which is set off between the gray-brown fleece and the black tip, forming a silver fog. . The snout, the back of the ears, the abdomen and the limbs of the silver-black fox are all black (those with white claws should be eliminated). There are silver hairs on the corners of the mouth and around the eyes, and a circle of silver hairs on the face to form a silver ring.

The silver-black fox has high legs, a thin waist and a thick and long tail. It is good at running and has agility in reflection. The snout is pointed and long, and the eyes of the young fox are sunken. When the fox becomes a fox, the eyes are large and bright, the ears are erect, and the senses of vision, hearing and smell are relatively sensitive.

After more than 100 years of artificial breeding, the silver-black fox has gradually increased in size and adapted to domestication. Due to the improved wild conditions, the quality of the plush has also been greatly improved. Male foxes are generally 6-8kg in weight, 66-75cm in length, and female foxes are 5.5-7.5kg in weight and 62-70cm in length. Finnish silver-black foxes have more animal feeds, and they are fatter and bigger.

WildSilver-black fox grows and lives in mountains, forests, grasslands and cold regions, and mainly eats meat, catching rodents, frogs, Fish, small animals and poultry. At the same time, some plant seeds, berries, roots, stems, etc. are also collected. Generally, they grow fatter in autumn. With the severe cold winter, food is short and gradually becomes thinner. The food of domestic foxes mainly includes meat, fish, eggs, milk, blood, animal offal, fish meal, grain seeds and soybean extruded feed, etc. The changes in fat and thinness are not obvious.

Foxes have underdeveloped sweat glands, and like dogs, they regulate their body temperature by opening their mouths and tongues and breathing quickly in hot weather. Therefore, breeders should pay attention to changes in ambient temperature, in hot summer, to prevent foxes from heat stroke. Silver-black foxes change their hair once a year, starting from March to April, from front to back, first from the head, then from the neck, forelimbs, to the buttocks and tail, and basically shedding from July to August. It also began to grow, and new needle hairs began to grow at the end of July. The growth sequence of new hairs is the same as that of depilation, and the fluff began to grow in large quantities. The color of summer hair is darker than that of winter. Silver and black fox skins mature later than blue fox skins, generally in mid-December, after heavy snowfall, all white boards are fully mature.

The food intake is smaller than that of blue fox and raccoon dog. Silver black fox comes into heat once a year and produces more litter than blue foxes There are few raccoon dogs, usually 4 to 6. The silver-black fox is more ferocious than the blue fox. During breeding, those whose nature is difficult to domesticate are gradually eliminated. After domestication, some silver-black foxes can be held in their arms and are easy to get close to people. Scientists in Finland have proved through observation and experiments that the silver-black foxes that are well domesticated and are not afraid of people have a high calving rate and a high survival rate. The life span of fox is 8 to 10 years, the breeding age can reach 8 years, the best breeding period is 2 to 5 years, and those after 5 years should be eliminated.
