Extract

Productivity in pigs can be improved by continued selection, however the impact of such selection on immune responses and resistance towards infectious challenges is not known. A risk is that this method may lead to a correlated reduction in the immune response and disease resistance. To estimate the effect of selection for performance traits upon immune responses, we compared levels of immune traits between divergent lines of Large White pigs selected for either lean growth under restricted feeding or feed intake.
