A winter feeding experiment evaluated effects of adding clinoptilolite zeolite clay at 1.2% of the diet on steer performance and nitrogen (N) volatilization loss. No differences were found in steer performance, removed manure composition or N balance; however, small numeric improvements were observed in ADG and F:G for steers fed zeolite. Adding zeolite clay to feedlot diets did not affect N loss in open feedlots using mass balance techniques.
