Extract

Pathogens (parasites, bacteria and viruses), when causing sub-clinical disease, affect the voluntary food intake, VFI kg/d, of animals, with subsequent reductions in rates of growth. However, no general quantitative framework for predicting the effects of different kinds and doses of pathogen on the VFI of animals has been proposed that could be integrated with existing models of growth. The aim here was to develop a general quantitative framework of VFI during exposure to sub-clinical doses of pathogens and to integrate such a framework with a general model of growth (Wellock et al. 2003).
