The aim of this study was to investigate whether the production results of pregnant gilts, grown under commercial farm conditions, could be increased by non-specific immunization with Baypamun (BPM), an immune response modifier. A non-treated group served as control (A), two experimental groups were treated on Day 6, 4 and 2 (group B), or on Day 5, 3 and 1 (group C), respectively, before their transfer from the sow keeping unit to the prefarrowing unit. The experimental gilts received 2 mL of BPM i.m., i.e. inactivated Parapoxvirus. Numbers of liveborn and stillborn piglets and the duration of farrowing were recorded. The analysis of variance with the type of treatment as independent variable showed a very significant difference in the number of liveborn piglets between the groups A and B, and in the number of stillborn piglets between the groups A and B as well as A and C. No differences in farrowing duration were recorded.
