Prevalence and clinical signs of postpartum dysgalactia syndrome at the first day after farrowing in farmed sows in the Republic of Macedonia

摘要

The objective of the present study was to determine the prevalence of postpartum dysgalactia syndrome (PDS) andassociated clinical signs in farmed sows in the Republic of Macedonia (RM) in the first 12-24 h postpartum. A total of 202sows of different parity and different genetic lines from 5 pig farms in RM were included in the study. The sows and theirlitters were clinically examined 12-24 hours after farrowing. Postpartum dysgalactia syndrome was detected in 23.3% of allclinically examined sows, while prevalence between farms ranged from 14.8% to 38.1%. Altered piglet’s behavior was themost frequent clinical pattern observed in 68.1% of the PDS–affected (PDSA) sows. Regarding the clinical signs in PDSAsows detected among farms, significant differences were observed in the altered piglet’s behavior (p0.05) and hypogalactia(p0.05). Endometritis was more often detected in older sows (90%) compared to endometritis in younger animals (44.4%).In addition, fever was also more frequently diagnosed in higher parity (≥3 parity) sows (55.0%) in contrast to other PDSAsows (22.2%). This study has demonstrated the presence of PDS in farmed sows in RM. High frequency of altered piglet’sbehavior found in this study could be an useful indicator for early detection of lactation problems in sows. Frequent pathologicalvaginal discharge in older sows indicates that endometritis plays an important role in the clinical manifestation of PDS. Furtherinvestigations should be conducted in order to identify specific risk factors associated with clinical PDS in farmed sows in RM.
