The core tips: The issue of sow production has always been the most concerned issue among farmers, post-natal care measures determine the post-natal utilization rate of sows, and the issue of post-partum sows not being eaten is described for reference only.
(I) Cause
1, calcium deficiency: dietary calcium deficiency or calcium phosphorus ratio is not appropriate, lack of sunshine or lack of exercise, vitamin D can not be converted into vitamin D, can reduce the concentration of serum calcium, gastrointestinal motility slow. If the course of illness is long, movement disorders will also appear.
2, vitamin B1 deficiency: Vitamin B1 can stimulate the stomach, so that peristaltic and secretory function. When vitamin B1 is lacking, it can cause weakened gastrointestinal motility, decreased gastric secretion, decreased appetite, and digestive disorders.
3, postpartum infection: elevated body temperature, mental depression, affect appetite or drinking desire.
4, post-partum weakness: poor feeding, pig weakness, lack of vitality; delivery time is too long, excessive fatigue, damage vitality; too much blood loss during labor, resulting in loss of blood, resulting in post-partum weakness, causing loss of appetite.
5. Gastrointestinal neurological disorders: Mostly occurring in the first-born sows, due to pain and fatigue, the sympathetic nerves are excited, the parasympathetic nerves are highly inhibited, the gastrointestinal motility and secretion function are extremely decreased, and the appetite decreases.
(b) Treatment
Once the sows show signs of loss of appetite or waste after delivery, they should immediately identify the cause and achieve symptomatic treatment:
1, due to failure caused by postpartum sow failure to eat, body temperature is generally normal or low, cold extremities distal, visible mucous membranes, lying more than a few. Do not want to move around, poor mental status, if not treated in time may lead to death. Treatment: Hydrogenated cortisone 7-10ml, 50% glucose 100ml, vitamin C20ml once intravenously.
2, due to postpartum sows a large number of lactation, blood glucose, calcium concentrations lead to sows postpartum does not eat. Treatment: 10% calcium gluconate 100-150ml, 10%-35% glucose 500ml, vitamin C10mlx2, intravenous injection, even for 2-3 days.
3, due to slaughter of the sow when the sow is not strict, the midwifery disinfection is not strict, pathogenic bacteria cause urinary system diseases caused by deficiency, leading to pigs postpartum does not eat, treatment: penicillin 4.8 million, 10% sodium coffee 10-20ml , Vitamin C10mlx2, 5% glucose normal saline 500ml, 2 times a day, intravenous injection 2-3 days, if the pathogen invades the uterus, use a disinfectant to wash the sow uterus.
4, sows postpartum due to colds, high fever caused by sows postpartum does not eat, in the clinical symptoms are more obvious, often performance: high body temperature, rapid breathing and heartbeat, limbs, ear tip chills, reduced breast milk contraction. Treatment: Gentamicin 5ml 5, analgin 20ml, vitamin C20ml, sodium and sodium coffee 10ml, 5% glucose saline 500ml intravenous injection, 2 times a day.
