Diagnosis and treatment of pig distiller's grains poisoning
Pig lees poisoning is often caused by lack of other feed combinations due to long-term feeding of lees, or sudden feeding of a large number of lees or moldy lees. The toxic components of distiller's grains are alcohol remaining in distillers' grains, and organic acids and fusel oils produced by continuous fermentation and rancidity of distillers' grains, such as acetic acid, n-propanol, isobutanol and so on.
1. Clinical symptoms
Six fattening pigs of 35kg~45kg raised by a farmer showed symptoms of poisoning after eating wine trough, of which one died. At the initial stage of poisoning, the feed intake of pigs decreased sharply. Suffering from depressed spirit, the body temperature is about 39.6 ℃, the skin is blue, constipation followed by diarrhea, gait instability, limb paralysis, lying on the floor can not afford, some excited and accompanied by a rash.
2. Pathological changes.
After dissecting the dead pig, it was found that the lung was congested, the pharynx and throat mucosa was slightly inflated, the esophageal mucosa was congested, the stomach inflated, the gastric mucosa was congested and bleeding, the gastric contents smelled of alcohol and vinegar, and the duodenal mucosa exfoliated and bleeding. There were blood spots in jejunum, ileum and cecum, blood and trace blood clots in the intestines, swelling of the rectum, exfoliation of mucous membrane, swelling of gallbladder wall, softness of myocardium and insufficiency of blood coagulation. The kidneys are swollen and brittle.
3. Diagnosis
According to the feeding condition, clinical symptoms and pathological anatomical changes, it was preliminarily diagnosed as distiller's grains poisoning. During the investigation of the feed condition, it was found that the distiller's grains used for feeding was completely exposed to the air, and the distiller's grains with a surface thickness of 1cm had been mutated and mixed with sour taste.
A small amount of variant distiller's grains was soaked in distilled water, filtered, placed in a beaker, and the pH value was determined. Preliminary measurement of pH

Matters needing attention in feeding lactating sows
Lactating sows are well managed, and sows are easy to estrus and maintain good reproductive performance after weaning, which can ensure that piglets can be transferred to nursing homes after weaning, so as to lay a solid foundation for improving the breeding rate. When feeding, we should pay attention to the following points: first, the average feed amount of sows from litter to weaning should not be fed on the average on the day of delivery, about 1 kg on the second day, and then increase by 0.5 kg per day until weaning 1 week later. Second, to ensure adequate energy for lactating sows.

Why do piglets grow slowly?
Some farmers reflect that the piglets raised at home grow very slowly. What on earth is the reason? According to the analysis, there are the following reasons. 1. Unreasonable weaning farmers adopt one more weaning method to raise pigs, and immediately after weaning, the piglets' original maternal-centered, cohabiting, stable and comfortable living conditions of piglets have suddenly changed, which is difficult to adapt and affect weight gain. The times of lactation of piglets should be gradually reduced within 5-6 days before weaning until they are completely weaned. 2. the feeding is not timely and the piglets are breastfeeding.
