Prevention and treatment of nutritional anemia in piglets

Nutritional anemia in piglets is a disease caused by the deficiency or lack of certain nutrients in feed, especially vitamins and minerals, which often occurs in piglets with poor feeding and management after weaning. The causes of this disease are many and complicated, and it often occurs under the joint action of many reasons. 1. Pregnant sows are malnourished or lack succulent feed, protein, vitamins and minerals for a long time, and the piglets will soon be in a state of anemia. two。 After birth, piglets have rapid growth and development, strong hematopoietic function and high iron requirements, but the iron content in pig milk is limited (about 7 milliliters of iron per day for normal growth of piglets, but only 1 milliliters of iron per day in mother's milk). 3. Smaller and emaciated piglets in the same litter often do not have enough milk and are easy to cause anemia. 4. Most of the farmers are raised in captivity, while the floor of the enclosure is mostly cement or plank, and the piglets start eating late, and the amount of iron absorbed by piglets from the outside is less. 5. Due to poor feeding and management of piglets and environmental impact, piglets have diarrhea and dysfunction, which affect the absorption of trace elements and nutrients. 6. Piglets after weaning are fed with rougher feed immediately or single feed for a long time, under the conditions of long-term unreasonable house feeding, lack of exercise, lack of sunlight or too short time to see the sun, it is easy to cause nutritional anemia in piglets. The piglets with symptoms are depressed, unwilling to move, anorexia, malnutrition, weak physique, dishevelled fur, dysentery, thin feces, pale mucosa of eyes, nose and oral cavity, gray-white auricle, increased respiration and pulse, but the body temperature is not high, the skin is cold by hand touch, and death can be caused by severe cases. Prevention and treatment 1. Strengthen feeding management, sows should be given feed containing appropriate protein, minerals and vitamins, and proper exercise and frequent exposure to sunlight. two。 Spread some clean iron-containing red clay in the pigsty for piglets to lick. 3. Drop a mixture of 0.25% ferric sulfate and copper sulfate on the nipple of the sow and let the piglet suck it with the milk. 4. After weaning, the iron content of 80 mg / kg in the feed of piglets was guaranteed to meet their growth needs. 5. Vitamin D colloidal calcium 1 ml ~ 2 ml, intramuscular injection, once a day for 3 days. 6. Intramuscular injection of 1 ml ~ 2 ml of living blood, or intramuscular injection of 0.1% sodium nitrite 0.5 ml, once a day for 5 days. 7. Liver essence injection 0.2 ml ~ 1 ml, 5% glucose solution 1 ml ~ 3 ml, mixed intramuscular injection, once a day for 5 ~ 7 days. -good materials, learning.
