Abstract
Two experiments were conducted in which zeolites were added to broiler diets at the 1% level beginning at 21 days of age. In one study, diets with different energy levels were used to determine if an interaction existed between zeolite supplementation and nutrient density. No beneficial effects of zeolite supplementation on body weights were observed in either experiment. There were no statistically significant differences in feed utilization between diets with and without zeolites, and the numerical differences could be accounted for by the addition of 1% inert zeolite.
