SPF Norway rats were subjects to metabolic trials to study the effect of zeolite on the resportion and utilization of synthetic amino acids contained in the feed ration. Low- and high-protein diets were tested, and 2% zeolite and the synthetic amino acids lysine, methionine and cysteine were added to the feed. The zeolite supplement had a positive influence on the utilization of the added amino acids. The weight gains increased, feed consumption per 1 g of weight gain decreased, and the effectiveness of feed conversion improved. Larger differences in these traits were recorded in the group where lysine was added to the low-protein feed.
