Indices of non-specific and specific humoral immunity in pigs immunomodulated with the Bioimmuno preparation and/or immunised with the Respisure One vaccine against mycoplasmal pneumonia of swine.

The purpose of the study was to determine the influence of the Bioimmuno preparation administered in feed and/or immunisation with the Respisure One vaccine on the development of selected indices of non-specific and specific humoral immune response against Mycoplasma hyopneumoniae (Mhp) infections in pigs. The study was performed on 28 piglets at the age of 4 weeks, divided into four equal groups. The biopreparations were administered according to the following pattern: group I--Bioimmuno (IFI Olsztyn, Poland) with feedstuff at amount of 1 kg/50 kg of feed for 48 h before vaccination with Respisure One (Pfizer) on day 28 of life; group II--Bioimmuno only (1 kg/50 kg feedstuff) for 48 h before vaccination with Respisure One of groups I and III; group III--Respisure One only on day 28 of life (2 ml/animal i.
