Abstract

Crossbred yearlings (n = 90) were allotted to one of 10 diets containing 0, 20 or 40% wet distillers grains (WDG) with or without vitamin E supplementation and distillers solubles (DS). Strip loin and tenderloin steaks were obtained and tested for their mineral (Ca, P, K, Mg, Zn, Fe, Mn, Cu, S, and Na) compositions using atomic absorption spectroscopy. Cattle fed DS diets had higher (P ≤ 0.05) levels of Ca, Fe, P, Mn, and S in strip loins than cattle fed non-DS diets. Feeding DS significantly reduced Mg and Na in tenderloins. Neither WDG nor vitamin E diets significantly affected the mineral composition of strip loins and tenderloins. In conclusion, feeding DS altered the mineral composition of strip loins. Changes in the mineral composition of beef are a consequence of dietary inclusion of DS, not WDG or vitamin E.
