Prevention and Treatment of Vitamin B1 Deficiency in Pigs
Symptoms: The sick pig is emaciated, with rough, dull hair and dry skin, and has a reduced appetite; some pigs vomit. In the early stage, constipation is common, with small pellets resembling sheep droppings, which often turns into diarrhea in the later stage. Lameness occurs in one or more limbs, with a stiff gait, difficulty standing, and trembling and shivering. Palpation causes no pain response, and reactions to stimuli are sluggish. The pig is listless, prefers to lie down, and appears fatigued. Some pigs have paroxysmal spasms. Body temperature shows little change. The onset is slow, and the course of the disease lasts more than 7 days.
Prevention and treatment: Feeding a complete compounded daily ration that meets nutritional needs, and paying attention to including feeds rich in vitamin B1 such as fine rice bran, wheat bran, beans, green vegetables, and green grass, can prevent the occurrence of this disease and further promote healthy and rapid growth and development of pigs. If a pig has already developed the disease, the original feed should be stopped and replaced with a complete compounded feed rich in vitamin B1; at the same time, the sick pig should be given intramuscular injections of vitamin B1 injection, with a dose of 250-600 mg for pigs weighing under 50 kg, twice a day, for 3-5 consecutive days.
