Abstract: | After a sudden outbreak of clinical porcine proliferative enteropathy (PPE) in a Croatian indoor breeding unit, the farm experienced decreased reproductive performance of Lawsonia intracellularis positive gilts. Conception-, farrowing-, and adjusted farrowing rates were lower (P<0.001) in gilts with positive L. intracellularis status. The number of live born and the total born litter size were significantly lower (P<0.001) in L. intracellularis positive gilts compared to seronegative ones. No differences were observed in numbers of stillborn and mummified pigs between the L. intracellularis positive and negative gilts. |
