Between December and March of next year, piglets, especially suckling piglets, are most prone to epidemic diarrhea and contagious gastroenteritis with diarrhea, vomiting and dehydration. The disease spreads rapidly, especially in swine farms where the pigs are relatively intensive, often affecting the whole group within a few days. If they are not rescued and treated in time, the mortality rate can reach 100% and the harm is extremely great.
1. symptom. The suckling piglet often develops vomiting after feeding, and soon there is severe diarrhea. The feces are yellowish or grayish white, with undigested small curds and odor. The pig's spirit is depressed, appetite is decreased, body temperature is slightly elevated or normal, dehydration occurs quickly, and weight loss occurs rapidly. The younger the age, the shorter the course of the disease, the higher the mortality rate, and it usually dies within 2 days to 5 days. The growth of piglets that were individually lucky enough to heal themselves was significantly affected, and most of the pigs developed stiff pigs. However, if timely treatment, can receive good results. Most of the symptoms of mild weaning pigs and adult pigs after infection were mild, manifested as reduced food, diarrhea, and sometimes vomiting after eating, and the systemic symptoms were not obvious. Normally resumes on the 4th - 7th.
2. prevention. Strengthen the winter feeding and management, in particular, pay attention to improving the supply of energy feed in the feed, strengthen the cold and warm, improve the overall resistance of the pigs; do a good job in the cleanliness and disinfection of the pig house, remove the house waste and waste every day, and Persist in the use of lime milk to sterilise the pens once every half month, and use 2%--5% per week to disinfect the utensils once; after the pigs infect the disease, they must promptly isolate the diseased pigs and treat the pigs Disinfect quickly with 2% sodium hydroxide or 5% - 10% lime milk.
3. treatment. Rescue treatment measures are: First, timely rehydration, each pig daily with 3.5 grams of sodium chloride, 1.5 grams of potassium chloride, 2.5 grams of sodium bicarbonate, 20 grams of glucose, add 1 liter of water after dilution For the piglets to drink. For pigs who refuse to drink water, 5%--10% glucose saline and 5% sodium bicarbonate solution should be injected intravenously or intraperitoneally in order to prevent acidosis and dehydration; secondly, at the same time as rehydration, the livestock and veterinary workers in our country practice A unique treatment for the winter diarrhea of ​​pigs with Newcastle Disease I strains was explored by diluting chicken Newcastle disease I strains with saline or distilled water 100-fold and using fresh water for each pig. 1 time - 2 times, each dose: 3ml - 5ml for intramuscular injection, 5ml - 10ml for medium pigs, 10ml - 20ml for pigs, and the amount of injection for each piglet 1 ml. This method is effective, generally only two times - three times Jiyu; the third is for the unconditional households, the use of alum for prevention and treatment is also a good way. For pigs exposed to the disease but not yet affected, 1.5% of alum can be added to drinking water, which has a good preventive effect. For infected or already infected pigs, use 3% alum solution to allow them to drink, usually 4 days - 5 days to recover on their own. For 7-day-old piglets, let them drink alum water, but also need to be combined with 0.25% of procaine solution do nest injection, each 2ml - 5ml each. For piglets less than 7 days of age, "piglet mother-fighting" can be practiced, and 1.5% alum liquid is prepared for the sow to drink. The alum's internal dosage is 2 g - 5 g each, which can effectively prevent piglet disease.
