Fig. 1From: Postpartum dysgalactia syndrome in sows: effects on behavior of sows and pigletsTwo observation periods of non-sleeping piglet activities from sows suffering from post partum dysgalactia syndrome (PDS+) and healthy sows (PDS−).

Based on matching with PDS+ sows, equivalent fictitious treatment times and observation periods were determined for the healthy PDS−sowsBack to article page
