Extract

The exposure of pigs to different pathogens compromises productivity, i.e. reduces weight gain and food intake (Balaji et al., 2000; Greiner et al., 2000), even in the absence of clinical disease. Infection also often causes the release of acute phase proteins and the proliferation of certain leucocyte subsets (Baumann and Gauldie, 1994; Licence and Binns, 1995). Therefore, it may be hypothesised that associations should exist between productivity and a range of immunological traits in apparently-healthy animals facing the same infectious challenge. This would be important in pigs suffering sub-clinical infections, as it would enable predictions of health status and effects of infection on performance. This study investigated such associations in apparently-healthy pigs facing unknown subclinical challenges.
