Table 1 Mean adenosine deaminase 1 (ADA1), adenosine deaminase 2 (ADA2) and total adenosine deaminase (tADA) activities (IU/L) in saliva from 38 sows with postpartum dysgalactia syndrome (PDS+) and 38 healthy sows (PDS-) in the periparturient period. Values for period B to G are compared to baseline (period A), where 0 h is the birth time of the first piglet and significant differences are indicated by the p -values
