Beware of Vitamin B Deficiency in Pigs in Winter
Symptoms: When vitamin B2 (riboflavin) is deficient, sick pigs grow slowly, vomit, develop skin rashes, and lose hair, etc. When vitamin B3 (pantothenic acid) is deficient, sick pigs have poor appetite, poor growth, diarrhea, coughing, hair loss, and poor coordination, especially showing a "goose-step" gait. When vitamin PP (niacin) is deficient, sick pigs completely lose appetite, become emaciated, have severe diarrhea, cracked skin covered with black scabs, nervous disorders, and anemia.
Prevention and treatment: When preparing pig rations, pay attention to fully supplying bran rich in vitamin B, silage, sprouted feed, etc. If corn is used as the main feed for a long time, it can cause vitamin PP (niacin) deficiency, so the amount of corn in the feed should be appropriately reduced and bran, silage, sprouted feed, and succulent tuber feed should be increased.
