Expert guidance
The hypoglycemia of newborn piglet is a metabolic disease caused by the decrease of blood sugar concentration of piglets, also known as swine pig disease. The disease is characterized clinically with obvious neurological symptoms. It mainly occurs in newborn piglets within 1 week of age, mostly in winter and spring, and rare in summer and autumn. The disease is easily misdiagnosed as colds, swine fever and other diseases by pig farmers and veterinary personnel. The mortality rate can reach 50% to 100%.
First, the clinical symptoms of piglets suddenly on the second day after birth, late in 3 to 5 days before the symptoms appear. In the early days, the piglets showed a lack of energy, limb weakness, muscle tremors, gait instability, swaying, reluctance to suck milk, outcropping or drowsiness into the grass, and lethargy. The skin was cold and pale, and the body temperature was low. The piglets were uncomfortable lying in the late stage and developed neurological symptoms such as convulsions or convulsions, empty chewing, runny nose, muscle trembling, nystagmus, opisthotonos, or swimming-like strokes on all four limbs. Feeling dull or completely lost, slow heartbeat, sick pig body temperature dropped to 37 °C ~ 36 °C, cold skin, eyes half closed, dilated pupils, mouth foam, and issued a scream. The sick pig began to be sensitive to external stimuli, then lost consciousness and eventually fell into a coma and died of failure. The course of illness does not exceed 36 hours.
Second, prevention and control measures
1. Strengthen the breeding and management of sows. Sows should adopt appropriate feeding methods according to the characteristics of different stages of pregnancy to ensure that sows get sufficient nutrients from the diet to meet the needs of fetal growth and development, but do not make sows too obese, and management should pay attention to Exercise to enhance the sow's constitution to produce high quality piglets. When dieting lactating sows, attention should be paid to appropriate energy and protein levels. The digestion energy per kg of diet should be higher than 11.72 MJ/kg, the crude protein level should be no less than 13%, and postpartum feeding should be reduced from much to much. Gradually increased, conditional can feed a green feed at night.
2. Pay attention to the cold and warmth of newborn piglets. The suitable temperature for raising piglets is: 1 to 3 days old 34°C to 30°C, 4 to 7 days old 30°C to 28°C, 15 to 30 days old 25°C to 22°C. Specific insulation measures can be used to set up a nursery room with a length and breadth of 60-80 cm each in the sow house, laying grass and installing bulbs to increase the temperature. After the first 3 days, the piglet is fully fed and placed in the nursery. After 3 days, the piglet can enter and leave the piglet. This will not only keep the body temperature of the piglet constant, but also effectively prevent the sow from crushed to death.
3. Fix the nipple, eat early, eat enough colostrum. Early eating colostrum can gain immunity early, get rich nutrition, produce body heat as soon as possible, and increase resistance to cold and disease. Keepers should pay attention to observations. Once a piglet is found to be competing for the same nipple, mediation must be promptly conducted. It is better to fix the weak piglets in the front and middle, and the powerful piglets are fixed in the middle and back so that the entire litter of piglets can develop evenly and neatly. When there is too much calving, some piglets can be fostered to other sows. It is generally necessary to ensure that the piglets eat colostrum within half an hour of birth.
4. Remedy in time after onset. Should strengthen the prevention of the disease, especially in the late sows to increase energy feed, or in the week before birth to 5 days after giving sows to add 50 to 100 grams of sugar each day, after mixing water into the feed for the pig to eat. Immediately after birth, piglets were given 20% glucose water orally, 5 ml per head, 4 times a day, and fed for 3 days. After the occurrence of the disease, it is necessary to quickly take sugar supplement measures, available 20% glucose solution 10ml, 2ml complex vitamin B fluid, 0.5ml dexamethasone, intraperitoneal injection, 3 times a day, until the symptoms are relieved and can self licking milk . In order to prevent secondary disease, 1 ml of intramuscular injection of lincomycin can be used, 3 times a day for 3 days. At the same time, it is necessary to relieve the cause of the disease, improve the feeding conditions, and remove the piglets into a warm barn. For human piglets with insufficient breast milk, artificial nursing should be given in time.
