Symptoms and Prevention and Treatment Methods of Vitamin B6 Deficiency in Foxes

This disease mostly occurs during the breeding period of foxes. When vitamin B6 is insufficient, male foxes develop azoospermia, while female foxes experience empty pregnancy or fetal death, and cub foxes show retarded growth and development. Therefore, once vitamin B6 is lacking in the feed, it will cause great losses to fox farming production.

Symptoms: Affected foxes show reduced appetite, keratinization of epithelial cells, and those with acanthosis develop paralysis of the hind limbs and microcytic hypochromic anemia. Pregnant female foxes show an increased rate of empty pregnancy, and the mortality rate of produced cubs increases. Male foxes lose sexual function or have no sexual or no sexual reflex, and have azoospermia. The testes of male foxes are obviously reduced, with degeneration inside the testes, and no sperm are detected. Cubs show retarded growth and development. Female foxes now show delayed estrus and pregnancy. According to reports, the occurrence of urinary stones in healthy male foxes is related to vitamin B6 deficiency.

Prevention and treatment: Use vitamin B6 preparations promptly for treatment. During the estrus period, use 1.2 mg once daily; during the hair growth cycle, use 0.9 mg; during the growth period, use 0.6 mg, which can be mixed into the feed and given. If it is an injection, it can be calculated proportionally for injection.

To avoid vitamin B6 deficiency in foxes, the amount of vitamin B6 in the daily ration is required to be no less than 0.9 mg per 100 g of dry matter, or 0.25 g per 418 kilojoules of feed.
