Prevention and Treatment of Vitamin Deficiency in Pigs in Late Winter and Early Spring

In late winter and early spring, pigs are prone to vitamin deficiency. The main reason is that green fodder is still relatively scarce; in addition, some @#@227@#@ households provide a single, unbalanced feed, and the pig houses lack sunlight and ventilation, so pigs are susceptible to vitamin deficiency in spring. The prevention and treatment methods are described below:

Vitamin A deficiency.

Symptoms: dry skin, dull coat, indigestion, reduced appetite, slow growth. In some cases, vision is weakened and the nerves are disturbed. In severe cases, spasms, circling, unsteady gait, incoordination of movement, and even paralysis of the hindquarters may occur. When sows develop this disease, it easily causes miscarriage or stillbirth, and the piglets born are blind; even if the piglets born appear normal in appearance, their constitution is very weak and they are prone to death.

Prevention and treatment: 20 grams of pine needles can be used, pounded into juice or decocted into juice, placed in the feed and fed once; once a day, for several consecutive days; more carrots, silage, and other feeds rich in vitamin A can also be fed.

Vitamin B deficiency.

Symptoms: stunted growth, vomiting, skin rash, hair loss, etc. When pantothenic acid is deficient, appetite is poor, growth is poor, diarrhea, coughing, loss of coat hair, and incoordination of movement occur, especially a "goose-step" like movement posture. When niacin is deficient, appetite disappears, emaciation, severe diarrhea, dermatitis, cracked skin covered with black scabs, nervous disturbance, and anemia occur.

Prevention and treatment: When preparing daily feed, pay attention to fully supplying feed rich in vitamin B. If corn is used as feed for a long time, it can cause niacin deficiency; the amount of corn in the feed should be reduced and bran, silage, sprouted feed, and succulent tuber feed, etc., should be increased.
