The living habits of foxes

Foxes live in a variety of environments, living in mountains, hills, forests, grasslands, mountains, deserts, plains and other places, often with stone cracks, tree holes, soil caves, bushes and so on as nests. Lying in caves during the day, coming out at night, agile, good at running, footprints very much like rabbit footprints, visual acuity, developed sense of smell and hearing, strong memory.

Foxes can crawl along cliffs, can swim and climb trees, are alert, cunning and paranoid, go out day and night, live in groups, have fierce struggle for survival among species, the law of the jungle, strong cold resistance, and can not bear the heat. I like to live in a dry, fresh and clean environment.

The lifespan of foxes varies from breed to breed. The life span of red fox is 8 ~ 12 years, breeding time is 4 ~ 6 years, silver and black fox is 10 ~ 12 years, breeding years is 5 ~ 6 years, life span of arctic foxes is 8 ~ 10 years, breeding years is 4 ~ 5 years, generally the best breeding age is 3 ~ 4 years old. Natural enemies in nature are wolves, lynx, hunting dogs, birds of prey such as eagles, vultures and so on.

Species classification of foxes

1. Arctic fox: also known as blue fox, white fox, snow fox, etc., distributed in the Arctic, with a body length of 50-60 cm, a tail length of 20-25 cm, a weight of 2.5-4 kg, a narrow face, a sharp mouth, round ears, fluffy tail hair, white tip, white body hair in winter, only black nose tip, gray-black body hair in summer, lighter ventral color, dense fluff and less hairs, and can live on ice sheets of minus 50 ℃. The plantar hair is very thick, moving alone or in groups.

2. Silver fox: also known as silver black fox, black fox, etc., because part of the needle hair is white, while the roots and tips of other needle hairs are black, and the middle part of the needle hair is silver white. It is native to the eastern Siberia region of northern North America. It is a mutant species of fur color of the red fox under wild natural conditions, with the same shape and appearance as the red fox, but with great differences in coat color. Mouth tip, round eyes, long ears, slender limbs, fluffy and long tail. It is a common breed of fox.

3. Firefox: also known as red fox, red fox, etc., with a slender body, sharp mouth, big ears, short limbs, and a long tail, widely distributed in Eurasia and North America, and introduced to Australia and other places.

4. Sand fox: it is a typical fox, the smallest of the genus Fox in China, its limbs and ears are slightly smaller than Firefox, the coat is light sand brown or light brown gray, with obvious grayish hue, the back is light silver gray or red gray, the abdomen is white and miscellaneous yellow, the chin is white, the whole body fur is thick and soft, the ears are big and pointed, the ear root is broad, the body length is 500-600 mm (excluding the tail), and the tail length is 250-350 mm.

The Feed preparation of Fox

1. Plant feed: plant feed includes corn, wheat and other grain seeds and their processing by-products, legume seeds such as soybeans and peanuts and their processing by-products, radish, apple, lettuce, cabbage, vetch and other fruits and vegetables.

2. Animal feed: in addition to poisonous fish, animal feed includes all kinds of marine miscellaneous fish, freshwater fish and their processing by-products (such as viscera), meat of all kinds of healthy livestock, poultry and wild animals and their processing by-products (such as claws, heads, wings, liver, lungs, skeletons, blood, ears, spleen, intestines), silkworm pupa meal, meat and bone meal, fish meal, dried fish, dry meal, feather meal, eggs (including feather eggs), dairy products, etc.

3. Additive feed: additive feed includes amino acids such as lysine and methionine, malt, cod liver oil, yeast, vitamins, minerals such as shell powder, bone meal, salt, various trace elements, antibiotics such as oxytetracycline, quinolinol, BHA.BHT, dihydropyridine and other antioxidants.

Breeding techniques of foxes

1. Before mating: silver fox and blue fox are the main foxes. The breeding preparation period of silver fox is from December to January of next year, and the breeding preparation period of blue fox can be extended to February. The main task of this period is to adjust the nutritional level of the diet and increase the proportion of protein in the diet so as to achieve the upper-middle body condition of foxes before breeding. Different nutrition standards should be applied to over-fat and too-thin foxes so that their body weight can reach 5-6 kg before mating. At the same time, light should be gradually increased to stimulate gonadal development, and foxes should be raised in Chaoyang.

2. Mating period: the mating period of silver fox is from February to March, and that of blue fox is from March to April. In this period, we should provide fodder with rich nutrition, good palatability and easy digestion, and appropriately increase the proportion of trace elements and multivitamin in the feed. Vitamin E 20 ~ 30 mg, onion or garlic 4 ~ 5 g and trace elements 1 ~ 1.5 g can be added to each kilogram of feed.

3. Pregnancy: female foxes have a particularly strong demand for nutrition during pregnancy. Pay attention to the supply of nutritious, comprehensive and high-quality feed, and avoid feeding mildew and spoilage feed to prevent abortion. At the same time, we should also do a good job in the hygiene and disinfection of the fox house, keep the fox house quiet and reduce the occurrence of stress factors as far as possible.

4. Lactation period: the female fox has a poor appetite at the initial stage of giving birth, it is best to feed it less frequently, 3 times a day after 3 days, fixed quantity. Young foxes should be given supplementary feeding when they reach the age of 25, usually twice a day. During supplementary feeding, fresh liver, fish, milk and eggs can be adjusted into paste, which can be fed by young foxes and put back to their original nest after supplementary feeding.

5. Breeding period: young foxes can generally be weaned and divided into nests at the age of 45 ~ 90 days, and can be flexibly mastered according to the growth and development of young foxes. Those who are strong and have the ability to live independently should divide their nests early, and those who are weak should postpone their litter division. The young foxes enter the breeding stage after dividing their nests, because the young foxes grow rapidly in this stage, and the fluffy grows rapidly in the later stage, which requires a lot of nutrients, so the young foxes should be fed well as far as possible in order to ensure the normal growth and development of the young foxes.

6. Disease prevention

① regular vaccination prevention: regular vaccination to enhance the specific immunity of foxes is an effective measure to prevent the epidemic. Vaccination should be carried out twice a year (when the seed is kept in December, 2 weeks after the offspring are separated from their nests in July), such as canine distemper vaccine and viral enteritis vaccine.

② drug prevention method: adding some drugs to the feed can effectively prevent the occurrence of some epidemic diseases. For example, in the feed, one tablet of oxytetracycline is given each week, which can not only prevent feed rancidity, but also prevent the occurrence of intestinal diseases.

③ cut off the route of transmission: when introducing foxes, veterinary departments should be asked to quarantine. In order to prevent the introduction of infectious sources, newly introduced foxes must be isolated and reared for about half a month after arriving at the scene. Observation should be made to confirm that there is no disease and then enter the field for breeding. Other animals should not be mixed with foxes in the same field to prevent transmission.

④ regular washing and disinfection: disinfection is one of the important measures to prevent or eliminate infectious diseases, therefore, the farm should be sprayed with peracetic acid every month to prevent disinfection, in order to control the occurrence of the disease, the feces under the cage should be removed in time every day, and the ground should be washed, so that the breeding environment is dry, clean, pollution-free and mildew-free.
