The effect of weaning induced stress on the relative gene expression of IFN-γ. A clear effect of gender can be seen whereby female calves had increased expression of IFN-γ versus male calves following weaning. * = P < 0.05, ** = P < 0.01, *** = P < 0.001. Lsmeans differ relative to pre-weaning baseline. a, bLsmeans differ between gender by P < 0.05.
