Results from current study demonstrated that diet with up to 18% glycerine can be fed to finishing bulls with no effect on carcass charac- teristics and meat quality, but meat fatty acid composition was affected. The inclusion of glycerine decreased saturated fatty acids and increased monounsaturated and polyunsaturated fatty acids, which provides a healthier meat. The effects of glycerine metabolism on LM fatty acid composition might require further research. Glycerine is a viable source of dietary energy, well utilized by bulls, and replaced corn successfully in beef finisher diets.
