This study was conducted to evaluate the effect of ferulic acid (FA) and clinoptilolite (CTL) supplementation on the growth performance, carcass characteristics, and meat quality of hair-breed lambs. Twenty-eight Kathadin male lambs (33.72 ± 3.4 kg) were randomly allocated to one of the four diets (n=7) under a 2 × 2 factorial arrangement to evaluate the effect of FA (0 or 300 ppm) and CTL (0% or 1%) during the last 40 days of the finishing phase. No interaction between additives was shown for growth performance, carcass characteristics and meat quality, with exception of the fatty acid profile ( < 0.05). FA reduced feed intake and carcass conformation ( < 0.05). Wholesale cuts were not affected by FA or CTL ( > 0.05). The L*, a*, and C* color parameters and some intramuscular fatty acids of the muscle were positively modified by CTL supplementation ( < 0.05). While there was no FA × CTL interaction, each additive could be used individually in animal nutrition to improve the feedlot performance and meat quality of the lambs.
本研究旨在评估补充阿魏酸（FA）和斜发沸石（CTL）对毛用品种羔羊生长性能、胴体特性和肉质的影响。28只卡他丁公羔羊（33.72±3.4千克）在育肥期的最后40天，按照2×2析因设计随机分配到四种日粮之一（n = 7），以评估FA（0或300 ppm）和CTL（0%或1%）的作用。除脂肪酸组成外（P<0.05），添加剂之间在生长性能、胴体特性和肉质方面未表现出交互作用。FA降低了采食量和胴体外形（P<0.05）。批发切块不受FA或CTL的影响（P>0.05）。补充CTL对肌肉的L*、a和C颜色参数以及一些肌内脂肪酸有正向改善作用（P<0.05）。虽然不存在FA×CTL交互作用，但每种添加剂均可单独用于动物营养，以改善羔羊的育肥性能和肉质。
