Additive feed for foxes?

The main results are as follows: (1) cod liver oil, yeast, malt and cottonseed oil are widely used in vitamin feed. Vitamin An is a substance that maintains the normal physiological function of animal epithelial tissue. Due to the lack of vitamin A, the growth and development of young foxes is delayed, and the reproductive ability of foxes decreases or loses their fecundity. Cod liver oil is the main source of vitamin An and D, feeding cod liver oil 800 to 1000 IU per day. The feeding method is to drop cod liver oil into the eating basin after sharing. If the liver and sea fish are fed all the year round, there is no need to give cod liver oil.

Vitamin E acts on the pituitary gland and stimulates hormone secretion, which can promote the normal reproduction of foxes, increase the litter size and the living ability of foxes. Sprouts are rich in vitamin E, mineral phosphorus, calcium, manganese and a small amount of iron, which is an indispensable feed for foxes during the breeding season. The production method of wheat malt is to wash the wheat, put it in a little salt water, soak it for 10 to 15 hours, remove it, lay it on a wooden plate, 1-2 cm thick, cover with a sack and place it in a light shelter of 15-20 ℃. Four or six layers can be placed on a three-dimensional wooden frame and sprinkled twice a day to keep the grain clean and moist. Light yellow or green malt is produced after 3-4 days, and can be fed when the malt grows to about 1 cm. Generally speaking, 1 kilogram of wheat can produce 2 kilograms of malt. Every 100 grams of malt contains 25 to 30 milligrams of vitamin E. When feeding malt, do not feed malt with mildew at the root of malt or reticular white mold. Foxes need enough vitamin C during pregnancy and lactation, which mainly comes from vegetables, such as lack of vitamin C, the mortality rate of young foxes is high.

(2) the mineral feed is mainly calcium, phosphorus and sodium chloride. If calcium and phosphorus are insufficient, the development of young foxes is hindered and rickets is easy to suffer from. Therefore, the feed for raising foxes needs to supply bone meal and salt all the year round. Especially in the breeding season, it is more important for female foxes and foxes. Generally, each fox needs 10 to 15 grams of bone meal per day. Salt is necessary for animals to maintain normal physiological activities. Generally, each animal needs 2-3 grams per day. If marine miscellaneous fish are used as the main feed in the diet, no salt or less salt should be added to the diet.

(3) the antibiotic feed is mainly made of oxytetracycline, which can not only inhibit microorganisms and prevent some diseases, but also promote the growth and improve the survival rate of young foxes.
