Six weanling male rats were fed a diet containing 90 percent opaque-2 maize for 28 days. The average gain in weight was 97 grams. In control rats fed on a standard hybrid maize the average gain was 27 grams. This confirms results of a previous feeding test on rats and demonstrates the superior quality of the proteins in opaque-2 mutant endosperm.
