title: [Vulvar discharge before parturition and a risk factor for postpartum diseases of the sow and for early postnatal piglet losses].
abstract: Periparturient biotechniques with prednisolon are widely used in Europe for the prevention of perinatal losses in intensive pig production. However, the routinely applied 100 mg prednisolon on the 113th day of pregnancy to the sow are not without controversy. In four intensive pig production units altogether 2143 sows treated thus were subjected to the evaluation of the following parameters: A: the presence or absence of vulvar discharge at the 110th day of pregnancy B: postparturient disease of the sow C: early postnatal piglet losses The results showed that the sows having prepartal vulvar discharge developed after prednisolon application significantly (p < 0.001) higher incidence of postparturient disease (20.5% versus 9.3%) when compared to the sows having no prepartal vulvar discharge. The early postnatal losses were significantly higher (p < 0.05) in sows having prepartal vulvar discharge and consecutive postparturient disease when compared to the healthy sows. It is the opinion of the authors that prepartal biotechnique with prednisolon (in order to reduce perinatal losses) in sows showing the signs of prepartal vulvar discharge is contraindicated.
