Net Protein Ratio of Stock Diets for Rats and Mice

Abstract

The net protein ratio of protein of six kinds of revised stock diets for rats and mice were compared with purified whole-egg protein and milk casein in six weeks old male Sprague-Dawley strain rats for a ten day experimental period, and they were given ten percent crude protein diets. The ratios of protein of the revised stock diets were lower than those of purified whole-egg protein, but were almost the same or superior to those of milk casein.
