Ninety-six Nellore young bulls were fed (90 or 117 day) diets containing ZH (8.33 mg/kg) for 0, 20, 30, or 40 days to evaluate the effects of days on feed (DOF) and length of zilpaterol hydrochloride (ZH) supplementation on meat quality. At the end of feeding period, animals were slaughtered, and samples of the Longissimus muscle were collected to evaluate the chemical composition, fatty acid profile, color stability, shear force, and sensory profile. DOF did not affect chemical composition, shear force, sensory tenderness, and most of fatty acids; however, animals fed for 90 d had lower redness ( p &lt; 0.01), sustained juiciness ( p &lt; 0.01), and more flavor ( p = 0.03) than those fed for 117 d. The ZH supplementation decreased lipid content and redness ( p &lt; 0.01), initial and sustained tenderness ( p &lt; 0.01), initial and sustained juiciness ( p &lt; 0.01), but increased protein ( p &lt; 0.01) and shear force ( p &lt; 0.01) as compared to non-supplemented animals. The ZH supplementation increased total PUFA, c9,c12-18:2, and 20:4-n6, and decreased c9-20:1 ( p &lt; 0.05). Feeding ZH impairs meat quality attributes of Nellore young bulls, regardless of duration of supplementation, while DOF has a small effect on meat quality properties.
