Fox breeding technique

Abstract: foxes are rare animals. In animal taxonomy, they belong to carnivores and canines. At present, blue foxes (also known as arctic foxes) and silver foxes are mainly raised in captivity. Foxes have high reproduction rate, strong disease resistance, miscellaneous food habits and good feeding. Here, I would like to introduce the breeding techniques of foxes in different growth periods.

Foxes are rare animals. In animal taxonomy, they belong to carnivores and canines. At present, blue foxes (also known as arctic foxes) and silver foxes are mainly raised in captivity. Foxes have high reproduction rate, strong disease resistance, miscellaneous food habits and good feeding. Here, I would like to introduce the breeding techniques of foxes in different growth periods.

Fox breeding technique

Foxes are carnivores, mainly feeding on rodents, fish, frogs, clams, shrimp, crabs, earthworms, birds and their eggs, insects and the carcasses of healthy animals. Under the condition of artificial feeding, feed is given priority to, and in the important feeding stage, some animal meat scraps such as intestines, stomach, head and bones are supplemented as feed, which can basically meet the needs of foxes.

1. Breeding before mating: foxes are mainly raised in silver and blue foxes. The breeding preparation period of silver fox is from December to January of next year, while 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. Breeding period: the breeding 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. Breeding during pregnancy: female foxes have a particularly strong demand for nutrition during pregnancy, so we should pay attention to the supply of nutritious, comprehensive and high-quality feed, and avoid feeding moldy and spoiled 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. Breeding during lactation: female foxes have a poor appetite at the initial stage of giving birth, it is best to feed them 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 during the 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 foxes. Those who are strong and have the ability to live independently should divide their nests as early as possible; those who are weak should postpone the time of 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.

Sanitary Management of Fox Farm

It is of great significance for improving fox skin quality and economic benefits for fox farms to formulate effective hygiene and epidemic prevention measures to reduce or eliminate fox disease. Therefore, in the daily feeding and management, we must adhere to the principle that prevention is more important than cure.

1. Epidemic prevention measures

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 prophylaxis: 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 cuts off all routes of transmission: ask the veterinary department for quarantine when introducing foxes. In order to prevent the introduction of infectious disease, the newly introduced foxes must be isolated and reared for about half a month after arriving at the field, observed and confirmed to be disease-free.

④ strictly forbids other animals, such as dogs, to enter the farm: other animals cannot be mixed with foxes in order to prevent transmission.

⑤ regular disinfection: disinfection is one of the important measures to prevent or eliminate infectious diseases. Therefore, every month, the farm should be sprayed with peracetic acid or peracetic acid to prevent and disinfect the whole farm in order to control the occurrence of the epidemic disease.

2. Sanitary measures

① to remove harmful substances in the feed, fish, meat feed before processing to remove impurities, such as sediment, deteriorated fat, etc., and then rinse fully with clean water before further processing.

② drinking water should be clean and pollution-free: water sources should be strictly managed so as not to flow into sewage and harmful substances. Drinking water utensils should be washed and disinfected frequently to prevent the breeding of molds.

③ controls the mildew of feed: do not feed stale or spoiled feed. Practice has proved that foxes eat rotten and deteriorated feed, light ones refuse to eat, anorexia, infection, and serious ones cause death.

④ cage hygiene: the feces under the cage should be removed in time every day, and the ground should be washed. During the fox birth period, the mat grass in the wooden box should be changed frequently. The mat grass should be used for cold protection and heat preservation. It must be soft and dry, pollution-free and mildew-free.

⑤ feed hygiene: it is absolutely forbidden to purchase feed from epidemic areas. Many infectious diseases are common to domestic animals and foxes. If foxes eat meat feed made from diseased livestock, the disease will occur.

Hygiene of ⑥ feeding utensils: feeding utensils should be disinfected frequently, wash buckets, pots and processing utensils with 0.1% potassium permanganate solution, etc., and can also be steamed and sterilized.

Daily feeding techniques of foxes

1. Principles for the formulation of ration

The diet is the feed composition of each fox on the 1st day, and all kinds of feed raw materials are rationally matched to form the diet. The scientific formulation of diet is the concrete manifestation of feeding standardization. The formulation of fox diet must follow the following rules.

① should pay attention to the important physiological characteristics of fox carnivores, and the diet must be based on animal protein feed and ensure the full price of the diet.

② should pay attention to the differences of nutritional needs of foxes in different production periods throughout the year, and not only ensure their maintenance needs, but also meet their nutritional needs of production.

③ makes full use of local feed resources and strives to mix and match multiple varieties to ensure the palatability of diets and the nutritional value of mixed feed. At the same time, the feeding cost should be reduced scientifically and reasonably.
