The causes of piglet diarrhea are complex, with high morbidity and great harm. How to effectively prevent diarrhea in piglets? Strengthening feeding management and doing a good job of disinfection and epidemic prevention are the most effective ways to resolve diarrhea in piglets. Specific should do the following:
(I) Feeding environment
1. Sexual conditions: A strict sanitation system should be established and implemented. Including: guard disinfection system, sanitation and disinfection system, empty bed and sow transfer disinfection, sow prenatal breast, vulva disinfection and piglet broken umbilical disinfection. Disinfectant should be changed regularly to make it effective. Faecal harmless treatment facilities.
2. Temperature and Humidity: Newborn piglets have inadequate temperature regulation systems and require higher ambient temperatures. General suitable piglets temperature l ~ 3 days 32 ~ 30 °C; 4 ~ 7 days 30 ~ 28 °C; 8 ~ 14 days 28 ~ 25 °C; 15 ~ 30 days 25 ~ 22 °C. Therefore, the litter box should be equipped with a piglet incubator. The ambient temperature of the pighouse is maintained at 22-25°C, the temperature of the incubator is maintained at 25-30°C, and the relative humidity is 50%-60%. Pay attention to ventilation during the summer and keep warm in the winter.
(B) Feeding Management
1. Sows feeding and management: Choosing good varieties of sows is fundamental to raising pigs, and sows’ nutritional status lays the foundation for multi-productivity and multi-fertility. The nutrition of pregnant sows adopts high, low and high feeding, that is, high nutrition level in the early pregnancy, low nutrient level in the middle period, and high nutrient level in the later period. The body condition of the sows before the birth is appropriately reduced by about 1/3 of the concentrate; the amount is gradually increased to 7 days after childbirth, so that diarrhea caused by over-concentration of the postpartum milk can be avoided.
2. Feeding and Management of Suckling Piglets: Piglets should be specially nursed at birth. Cut off the umbilical teeth and eat colostrum as soon as possible. Adjust nipples or nests depending on the number of litters and the body condition of the piglets. 2 to 4 days of intramuscular injection of blood serum. Experiments show that iron supplementation can effectively reduce the occurrence of the disease. The incidence rate decreased by 4.2% compared with the control group, and the mortality rate decreased by 1.67%. 3 to 10 days old sodium selenite-E mixture selenium injection. However, it should be noted that supplementation of iron and selenium should be separated by more than 7 days to prevent antagonism and affect the effect. In order to reduce the stress caused by the piglets' future feeding of rations, piglets fed with a flavoring agent such as bovine must be started at 7 days of age so that the gastrointestinal digestive system of the piglets can adapt to the vegetal protein in the stomach before weaning. The bowel function is exercised, thereby reducing the effects of nutrient stress from breast milk to feed. The weaning pigs are gradually weaned, ie, the number of nurses is reduced 1 to 5 days before weaning, and the sows are moved at night in the last 2 days. The weaned piglets should be kept in the original circle for a period of time to reduce the influence of psychological and environmental stress.
3. Feeding and Management of Weaned Piglets: The cause of diarrhea in weaned piglets is on the one hand from weaning stress, and on the other hand from short-term allergic reactions of piglets to weaning rations. The consequences of both effects cause E. coli attachment and proliferation in the intestine and increased sensitivity to enterotoxins, causing diarrhea. Therefore, reducing weaning stress and this transient allergic reaction can help prevent diarrhea. There are two ways: First, the amount of piglets before weaning reaches 600 g to form a mature digestive system that is not affected by the severe conditions of weaning; second, the transitional ration of weaning gradually adapts the digestive system of the piglet to the weaning ration.
(c) Vaccine immunity
For some pig farms, E. coli, infectious gastroenteritis and epidemic diarrhea are more serious, and pregnant sows can be immunized with vaccines.
(D) Specific prevention and treatment of probiotics can regulate the intestinal environment of piglets, so that beneficial bacteria become dominant bacteria, and provide a good ecological environment for the digestion and utilization of feed.
The experiment showed that when the piglet was born, it was orally administered with a variety of beneficial bacteria, algae, etc. The bio-occupation factor was 1 mL, and then colostrum was eaten in time to strengthen feeding and management. The piglets did not need to use antibiotics within 10 days of age to prevent the piglets from appearing yellow.ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢ ç—¢.
In short, strengthening feeding management and disinfection and epidemic prevention systems is the most effective way to solve the problem of diarrhea in pig farms on a large scale, but this is often not valued by managers in production. With the large-scale development of animal husbandry, competition between industries has become increasingly demanding for husbandry and management. This requires internal management to tap potentials, establish a sound job responsibility system, implement link cost accounting, and complete mature production technology assembly facilities. And to effectively implement and improve productivity, so that companies can be invincible in the fierce market competition.
