The reason why a 40kg piglet won’t eat and slowly loses weight
The inability of sows to stand after giving birth may be due to being too fat
Postpartum paralysis of sows is caused by the physical weakness of sows after giving birth. After giving birth, their limbs cannot stand and their consciousness decreases. A disease of paralysis, also known as postpartum wind. It is a common disease in sows. Mainly due to insufficient or imbalanced proportion of calcium and phosphorus in the diet; long-term feeding of corn, cereals, beans and other concentrates, inorganic phosphorus cannot be supplemented; excessive production intensity and other factors, sows usually lactate for 20 days Around 15 to 35 days after delivery, the loss of calcium and phosphorus in the body reaches its highest point, with the most paralysis occurring in sows 15 to 35 days after delivery and a few days before delivery.
Before paralysis, there was loss of appetite or refusal to eat, slow movement, generally dry and hard feces, preference to drink clear water, bulging of the ground, and abnormal eating. Body temperature and pulse are normal. After paralysis, there will be back arch, constipation, sluggishness, inability to stand for a long time, exchange of steps, hindquarters swinging and weakness, loss of consciousness, in severe cases, lying on the ground, screaming when touched, decreased lactation, and refusal to breastfeed. If not treated in time, the sow will become emaciated and die. Although the mortality rate of this disease is extremely low, it makes sows lose their breeding value, affects the growth and development of piglets, and even causes the death of piglets, resulting in huge economic losses and should be taken seriously.
The cause of postpartum paralysis in sows
Modern veterinary medicine believes that postpartum lactation affects the calcium content in the blood, leading to this disease. In addition, malnutrition and improper feeding and management, such as calcium deficiency or imbalance of calcium and phosphorus ratio during pregnancy; insufficient feed or nutritional deficiencies; loss of Qi and blood after delivery; cold climate in early spring and lack of exercise for sows; cold and damp pens and cold winds. Meridian blockage, etc. can lead to this disease. In addition, factors such as lack of sunlight exposure, excessive fetal size, and damage to the sciatic nerve during delivery can also cause the disease.
Clinical symptoms of postpartum paralysis in sows
Sows are depressed after delivery, have decreased appetite, decreased lactation, accelerated heartbeat, unsteady standing, weakness in both hind limbs, and swaying when walking. In the later stages, he is unable to stand, often lying on his side on the ground, with his head tilted downward, and his two hind limbs separated in a figure-eight shape, and eventually becomes paralyzed. Muscles atrophy over time, and bedsores sometimes occur.
Preventive measures for postpartum paralysis of sows
Usually, shell powder, eggshell powder and calcium carbonate should be supplemented in pig diets; sows should be supplemented with supplements during the late pregnancy and lactation period. Feed bone meal, fish meal and miscellaneous bone soup, and supplement high-quality hay powder, leguminous grass (alfalfa) and green feed during the winter and spring rainy seasons; the pig house must be kept clean and dry; after sows give birth, the pig house must be provided with more bedding; Prevent cold wind from blowing, keep the pig house warm and spacious, and have sufficient sunlight. Sows should bask in the sun more during pregnancy. Let the sows exercise in the sun for 2 to 3 hours every day. The feed is easy to digest and rich in nutrients. The protein, mineral and vitamin feed should have an appropriate ratio of calcium to phosphorus; for sows with a history of postpartum paralysis, 100 ml of 10% calcium gluconate should be injected intravenously 20 days before delivery, once a week to prevent the occurrence of this disease.
Treatment method for postpartum paralysis of sows
1. Add bone meal to the feed, 30 to 50 grams per pig per day
2. Vitamin ammonium butyrate calcium injection Inject 5 to 10 ml intramuscularly, and then inject again after 3 days.
3. Add 3 to 6 grams of superphosphate or bone meal to the feed every day for 10 to 15 days.
4. Dexamethasone injection 5 ml-10 ml, once intramuscularly, once a day.
5. 100~150 ml of 10% calcium gluconate injection, once intravenously, once a day.
6. Breast air supply method: Sterilize the nipple and milk guide needle, use a 100 ml syringe to inflate the breast, and stop the air supply when the breast bulges slightly. The purpose is to reduce milk production, thereby slowing the loss of calcium in the blood.
7. For seriously ill pigs, 100 ml to 200 ml of 10% calcium gluconate solution, 10 ml of 12.5% vitamin C, 20 ml of compound sodium salicylate, and 500 ml of 50% glucose can be injected intravenously once. Repeated administration once every 5 days has good results.
8. Traditional Chinese Medicine Therapy: Take "Compound Dragon Bone Soup" orally. Prescription: 300 grams of dragon bone, 50 grams each of angelica root and rehmannia glutinosa, 15 grams of safflower, 400 grams of malt, decoction twice in one, take it twice a day in the morning and evening, and use it for 3 doses in a row. The effect is remarkable.
9. Take 100-150 ml of 10% to 20% calcium gluconate and infuse it intravenously once a day. Recipe 5: Take 25 grams each of angelica root, fangfeng, earthworm, and black snake, 20 grams of safflower, earthworm, 12 grams of myrrh, 15 grams of blood root, rice wine as a guide, mix with warm water, and take it once.
