C-reactive protein in monitoring and evaluation of effects of therapy of the MMA syndrome of sows

The elevated concentration of CRP in sows at the early stage of the MMA reflected the inflammation in the reproductive tract and in the mammary gland. Monitoring the level of CRP during the first days after parturition may be used to diagnose early stages of the MMA and to start therapy. In the treated MMA sows the level of CRP steadily decreased, and by the end of the experiment it had returned to the normal level. In the non-treated MMA sows CRP persisted at a high level and at day 10 of the experiment it was 13 times higher than in the treated animals and 16 times higher than in controls. Measurements of serum CRP are valuable in monitoring the health status of sows after parturition and should be introduced as the diagnostic method of the MMA syndrome in sows. The determination of the concentration of serum CRP during the first two days after parturition should be used for diagnosis of the early stages of MMA syndrome in sows and to start therapy when clinical symptoms of MMA are still absent.
