Do mycotoxin contaminated diets and yeast cell wall adsorbent affect meat quality of Nellore bulls finished in feedlot? - A short communication.

Abstract

Ninety-six Nellore bulls (430\u202f±\u202f13\u202fkg and 24\u202fmonths) were assigned to a completely randomized block design (2\u202f×\u202f2 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\u202fg/animal/d; Factor 2). The diets were provided during 97 d. The meat chemical composition was unaffected (P\u202f≥\u202f.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\u202f≥\u202f.11), cooking loss (P\u202f≥\u202f.24) and Warner-Bratzler shear force (P\u202f≥\u202f.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.
