| description | Grass-finished beef (GFB) has demonstrated wide nutritional variations with some GFB having a considerably higher <i>n</i>-6:<i>n</i>-3 ratio compared to grain-finished beef. To better understand these variations, the current study investigated the effects of commonly used supplemental feeds on the nutritional profile of GFB. This two-year study involved 117 steers randomly allocated to one of four diets: (1) grass+hay (G-HAY), (2) grass+baleage (G-BLG), (3) grass+soybean hulls (G-SH), and (4) baleage+soybean hulls in feedlot (BLG-SH). Feed samples were analyzed for their nutritional value, and beef samples underwent analysis for fatty acids (FAs), vitamin E, minerals, lipid oxidation, and shear force. FAs were measured by GC-MS, vitamin E was analyzed chromatographically, minerals were analyzed by ICP-MS, and lipid oxidation was measured via a thiobarbituric acid reactive substances (TBARS) assay. G-SH beef had the highest <i>n</i>-6:<i>n</i>-3 ratio (<i>p</i> < 0.001), while BLG-SH beef contained less vitamin E (<i>p</i> < 0.001) and higher TBARS values (<i>p</i> < 0.001) compared to the other groups. G-HAY beef contained more long-chain <i>n</i>-3 polyunsaturated FAs compared to the other groups (<i>p</i> < 0.001). In conclusion, G-HAY beef had the most beneficial nutritional profile, while soybean hulls increased the <i>n</i>-6:<i>n</i>-3 ratio of beef. |
