Abstract

Crossbred steers (n = 64) were grazed on warm- or cool-season grasses, without or with energy supplementation of wet distillers grains with solubles (WDGS), and were finished on a corn-based diet with or without 35% WDGS. Grass-type was the major contributor in determining the biochemical composition of L. dorsi steaks, with warm-season grasses causing increased concentrations of moisture and zinc and decreased concentrations of magnesium. Aging 28 days instead of 7 days increased pH and caused an increased concentration of carbohydrates, and non-heme and heme iron in B. femoris steaks. Diet, especially grass type, during grazing, can alter the end composition of beef.
