The role of vitamins with particular impacts on immunity and gut integrity (specifically vitamins A, D and E) is well known in poultry nutrition in building immunity

I agree that it is well understood that these vitamins are involved in immunity and gut integrity. The question remains, however: "how do we strategically manipulate dietary levels to achieve specific outcomes?". Deficiencies in these nutrients can impair various aspects of immune function, but once the requirement has been met, are there further responses in targeted immune effects that can be achieved? What about interactions, or negative effects of over-supplementation, which have also been demonstrated? In the context of an increasing reliance on host immunity (i.e. removal of growth-promoting antibiotics), do we know enough to strategically apply what is known, or identify the knowledge gaps that remain?
