Piglet diarrhea Diarrhea is very common problems, diarrhea in 20-30% of the general rate of mortality at 2-4%, but in some pig farms in postweaning diarrhea rate high, even up to 70 - 80% mortality rate of 15-20% for pig producers, causing great economic losses.


Weaning piglet diarrhea generally occurs 3-10 days after weaning, the seventh day orgasm, usually atherosclerosis, or the formation of watery diarrhea, indigestion of food within the inclusion, if not detected and treated quickly died because of dehydration. The reason, mainly: weaning, the maternal antibodies declined sharply, resulting in resistance decrease. piglet digestive physiology is not perfect and does not meet the high protein feed plant functional gastrointestinal disorders, coupled with high pH gastrointestinal tract, digestive enzyme activities can not play its due role and induce diarrhea. weaned stress, especially environmental stress, when discounted over 10 degree temperature difference between day and night, the diarrhea rate will rise 25-30% in conditions of high humidity will also markedly increase the number of diarrhea. inappropriate feeding mode: restricted feeding, and excessive over-feeding, feeding off the formation of hunger and diarrhea. immune responses, especially in the feed corn - soybean meal diet when, and contains more anti-nutritional factors of soybean meal when raw soybean meal, resulting in a delayed type hypersensitivity intestinal epithelial cells, causing watery diarrhea. gastrointestinal flora.

Off umbilical, tails, cutting teeth, ear number, etc. to play strictly with disinfection with iodine to prevent infection.


Piglets 7 days beginning with a small amount, number of feeding methods for their feeding, to exercise their stomach's digestive function. Possible to add the feed by 0.2% in the only eco-C211 (probiotics, Dalian 3 meter R & D), can improve digestion and absorption, improve feed utilization, maintaining a balanced intestinal flora, strengthen immunity, prevent diarrhea.


On lactation feed should be given full price, to ensure all their nutritional needs, so that piglets receive adequate and complete nutrition milk. Sow's milk is too thick, milk fat and protein content in high piglets indigestion after eating, can cause Diarrhea.

3 Immunization Pregnant sows 20-30 days before birth. Sea Point after the injection of each pig transmissible gastroenteritis and porcine epidemic diarrhea in 2 4 ml of inactivated vaccine, newborn piglets were passive immunity through colostrum eating, can prevent viral diarrhea.


Pregnant sows at 40 days and 15 days each antenatal intramuscular injection 1, E coli K88, K99, 987P trivalent inactivated vaccine, each 5 ml per head, newborn piglets were passive immunity through colostrum to eat can prevent yellow and white diarrhea.
