The biological values of whole white maize and whole yellow maize are 76 ± 1.91 and 67 ± 0.98 at approximately 8 per cent. protein level. 2. The proteins of white maize are significantly better than that of yellow maize. 3. Supplementation with lysine and tryptophane separately does not increase the nitrogen utilization of yellow maize to any marked extent. 4. Supplementation with lysine and tryptophane simultaneously markedly increases the nitrogen utilization of the yellow maize protein.en© 1940 ARC - Onderstepoort and Faculty of Veterinary Science, University of Pretoria (original). © 2017 University of Pretoria.
