The loss of Vitamin A potency under these experimental conditions led to the conclusion that the feeding of stabilised Vitamin A incorporated in licks fed to range animals is unpractical.en© 1962 ARC - Onderstepoort and Faculty of Veterinary Science, University of Pretoria (original). © 2016 University of Pretoria.
