newborn piglets digestive ability is poor, weak resistance, prone to diarrhea. for the control of piglet diarrhea incidence, must find out the law and master of piglet diarrhea prone and its three stages.
incidence of piglet diarrhea in piglets and weaned off, suffered 3 major violations of diarrhea:
the first time period for diarrhea piglet yellowscour, often occurs in piglets after 3 days ago, the early onset of escherichia coli diarrhea. morbidity and mortality are high, all year round may occur, but in cold winter and early spring onset more. clinical to pull loose stool as the main symptoms of yellow, mostly due to housing pollution, disinfection is not complete, cold and humid, climate change, cold and eat colostrum inadequate.
preventive measures: 1, should eat colostrum, obtain the maternal antibody from colostrum; 2 blood injection timely iron blood; 3 piglets piglets with postpartum life-saving liquid, morninglight antidiarrheal fast 2--5 drops, 1 hours after feeding colostrum to anti-inflammatory bacteria, reduce and prevent piglet diarrhea.
the second is prone to diarrhea of piglets diarrhea outbreak period, 2-4 weeks of age, especially the piglets incidence 10-20 days at most, accounting for more than 35% of the total incidence. this is the infectious disease of suckling piglets caused by pathogenic escherichia coli. piglets from white, yellow green or gray white feces, thick atheromatous smelly fishy smell. cold or heat preservation measures, thieves invasion, fecal contamination, wet. 2 weeks postpartum piglets, although still infants, but the antibody in breast milk has started to decline, low resistance, is the fundamental reason for the outbreak of piglets pullorum disease.
preventive measures: 1, the use of zhengchangsheng (each containing 1 billion grams of probiotics) for prevention and treatment of drinking water; the mother of 2 young take morninglight mu zi; 3, in the water by adding appropriate oral rehydration salts and antibiotics such as amoxicillin morninglight, prevention of dehydration, electrolyte supplement, alleviate acidosis and supplementary energy treatment of piglets diarrhea, diarrhea, dysentery, colibacillosis, viral enteritis etc.,
the third is the diarrhea of weaned piglets diarrhea. all of a sudden leave sows piglets care, suddenly suffered environmental and nutritional stress, resulting in a decline in piglets indigestion, diarrhea and resistance; weaning after gastrointestinal physiological environment changes, coupled with the mother separation, and nutritional stress, resulting in decreased growth of piglets against disease, caused by blocked, 1-2 weeks of weaned piglets especially within 2-10 days, the third peak of piglet diarrhea deaths. the fatality rate is generally 10%-20%, and if the dehydration occurs, the fatality rate can be as high as 40%.
piglet diarrhea by early prevention of feeding and management do a good job of lactating sows:
(1) feeding sows with full price and not too high protein level. to maintain the relative stability of feed, do not feed moldy, dreg fodder, and green fodder, ensure good milk.
(2) feeding fat. add fat to the feed late in pregnancy to promote the synthesis of milk fat. improve the cold resistance of newborn piglets and reduce the diarrhea of piglets.
(3) provide a good feeding environment for piglets, and make sure that the pig house is warm and dry, clean and sanitary, fresh air, no pollution in the environment, and suitable for temperature and humidity.
(4) prenatal prenatal disinfection available junduging iodine or toxic bacteria might kill pig disinfection.
suckling piglets (5) breast area before disinfection, use warm water to scrub the breast area, then junduging sow belly and iodine, nipple disinfection, prevent disease enters by the mouth.
(6) early feeding and early feeding can stimulate the development of the stomach and intestines, strengthen the function of the stomach and intestines, help the digestion of the piglets, increase the digestibility of the feed, and reduce the gastrointestinal diseases.
(7) feed the organic acid to feed the whole price of piglet,
(8) take out whole feeding mode can eliminate the infected pigs, thorough disinfection pens, purifying aquaculture environment, is conducive to the prevention of piglet diarrhea disease.
