THE IMPACT OF CLINICAL VARIATIONS IN POSTPARTUM MM A SOWS ON PIGLET DIARRHEA

摘要

Mastitis, metritis and agalactia (MMA) complex usually occurs within 12 hours to 3 days post of parturition. Sign of fever, anorexia, vulva discharge and mastitis might all accompany the basic change and the growth rate and survival of the litter areusually affected. This syndrome might reduce the transmission of maternal antibodies to piglets, leading to low immunity in piglets. Diarrhea in piglets caused by pathogenic organism, low immunity, lack of maternal antibodies or a sub-optimal environment. Herds with prevalence of 6.9% MMA, there had 4% total pig bora and 12.9% pig mortality in the first week of age. Litters from sows with post parturient MMA complex had 1.8 times higher to getting diarrhea than litters from healthy sows, however research into MMA should be focused on the variations in clinical expression. As these data, this study was conducted to investigate on the impact of sows with different clinical variations of MMA on neonatal diarrhea in piglets.
