Meat quality of heifers finished on pasture with tropical grass and supplemented with glycerin

Abstract Glycerin is an organic compound with an alcoholic function and can be esterified into fatty acids to form triglycerides. Due to the increasing availability of glycerin, studies that determine the best level of its inclusion in diets for ruminants are needed. This study evaluated the effects...
