Table 1 Parity and productions results for 38 sows with postpartum dysgalactia syndrome (PDS+) and 38 healthy sows (PDS-) together with key clinical parameters in time interval A, E and F. The number of observations (n) in each interval varies because of variation in individual sampling times relative to parturition (0 h) [For further explanation see Additional file 1]
