Abstract

Ninety-six Nellore bulls (430 +/- 13 kg and 24 months) were assigned to a completely randomized block design (2 x 2 factorial arrangement of treatments) to evaluate meat quality. Dietary treatments consisted of natural or exogenous contamination with mycotoxins (Factor 1), with or without yeast cell wall adsorbent (10 g/animal/d; Factor 2). The diets were provided during 97 d. The meat chemical composition was unaffected (P >= .37) by the factors and the averages of variables were 74.2% moisture, 22.7% protein, 1.04% ether extract, and 2.10% ash. The L{*}, a{*}, b{*}, E{*}, C{*} (P >= .11), cooking loss (P >= .24) and Warner-Bratzler shear force (P >= .17) were also similar among factors. In conclusion, low mycotoxin contamination and yeast cell wall based adsorbent do not affect meat quality of Nellore bulls finished in feedlot. (AU)
