What are the additive feeds used for foxes?

(1) The most commonly used vitamin feeds include cod liver oil, yeast, malt, cottonseed oil, etc. Vitamin A is a substance that maintains the normal physiological function of animal epithelial tissue. A deficiency of vitamin A causes stunted growth and development in young foxes, and reduced or lost reproductive capacity in breeding foxes. Cod liver oil is the main source of vitamins A and D; the feeding amount of cod liver oil is 800-1000 international units per animal per day. The feeding method is to drip cod liver oil into the food bowl after the food is divided. If liver and sea fish are fed year-round, there is no need to give cod liver oil.

Vitamin E acts on the pituitary gland, stimulates hormone secretion, and can promote normal reproduction in foxes, increase the number of offspring and the vitality of young foxes. @#@245@#@Sprouts are rich in vitamin E and contain the minerals phosphorus, calcium, manganese and a small amount of iron, and are an indispensable feed during the fox breeding period. The production method for wheat sprouts is to wash the wheat clean, put it into clean water with a little table salt, soak for 10-15 hours, remove it, spread it flat in a wooden tray at a thickness of 1-2 cm, cover it with gunny sacks and place it in a dark place at 15-20°C. A three-dimensional wooden rack can hold 4-6 layers. Water must be sprinkled twice a day to keep it clean and keep the wheat grains moist. After 3-4 days, pale yellow or green wheat sprouts grow. When the sprouts grow to about 1 cm, they can be fed. Generally, 1 kg of wheat can produce 2 kg of sprouts. Every 100 grams of sprouts contains 25-30 mg of vitamin E. When feeding sprouts, do not feed sprouts whose roots have become moldy or on which a net-like white mold has grown. Breeding foxes need sufficient vitamin C during gestation and lactation, which mainly comes from vegetables. If vitamin C is lacking, the mortality rate of young foxes is high.

(2) Mineral additive feeds are mainly calcium, phosphorus and sodium chloride. If calcium and phosphorus are insufficient, the development of young foxes is hindered and they are prone to rickets. Therefore, fox-raising feed needs a year-round supply of bone meal and table salt. This is especially important during the breeding season for female foxes and growing foxes. Generally, each animal needs 10-15 grams of bone meal per day. Table salt is necessary for animals to maintain normal physiological activity. Generally, each animal needs 2-3 grams per day. If sea trash fish are the main feed in the daily ration, do not add table salt or add only a little table salt to the daily ration.

(3) Antibiotic additive feeds are mainly antibiotics made from oxytetracycline. They can play a certain role in inhibiting microorganisms and preventing some diseases, and can also promote growth and increase the survival rate of young foxes.
