Abstract

Metabolic interactions between zinc and vitamin A have been postulated for human and animal nutrition (Smith, 1982). In particular, it has been demonstrated that zinc deficiency has a strong adverse effect on the vitamin A status. Conversely, to what degree vitamin A supplements affect the zinc supply status when inadequate zinc is provided has hardly been studied. In the work presented here, we examined such interactions between zinc and vitamin A metabolism in 4 experiments with rats and swine.
