Our hypothesis suggests an improvement in carcass and meat quality of pasture‐finished animals by introducing concentrate feed into diets. This study aimed to evaluate the effect of different levels of protein‐energy supplementation on carcass and meat characteristics of Texel lambs raised on Brachiaria pastures, and compare the results with those obtained from confined animals. Thirty 2‐month‐old intact lambs were divided into five treatments: pasture with mineral supplementation, pasture containing daily supplies of 0.8, 1.6, and 2.4% BW protein‐energy supplementation, and confinement (reference treatment). All animals were slaughtered 104 days after the beginning of the experiment. Lambs submitted to 1.6% and 2.4% BW supplementation presented similar characteristics to animals kept in confinement and were superior to animals treated with 0 or 0.8% of BW supplementation levels (p  < .05). Increases of subcutaneous fat thickness were verified for 0.0, 0.8, 1.6, 2.4% BW, and confinement treatments, being respectively of 0.25, 0.74, 1.61, 1.69, and 1.98. Conversely, treatments had no influence on meat physical‐chemical characteristics, being all considered moderately soft, juicy (tender), and with mild tastes and odors. Lambs raised on Brachiaria pastures have high‐quality meat, but more protein‐energy supplementation is needed to be an alternative for the feedlots for young animals.

在 Brachiaria 牧场和饲养场系统中饲养的 Texel 羔羊的胴体特性和肉质。

我们的假设表明，通过在日粮中引入精饲料可以改善放牧动物的胴体和肉质。本研究旨在评估不同水平的蛋白质能量补充对臂形饲养的特塞尔羔羊的胴体和肉特性的影响牧场，并将结果与​​圈养动物的结果进行比较。将 30 只 2 个月大的完整羔羊分为五个处理组：补充矿物质的牧场、每日补充 0.8%、1.6% 和 2.4% BW 蛋白质能量补充剂的牧场，以及禁闭（参考处理）。所有动物在实验开始后 104 天被屠宰。提交 1.6% 和 2.4% BW 补充剂的羔羊表现出与圈养动物相似的特征，并且优于用 0 或 0.8% BW 补充剂水平处理的动物（p < .05)。经验证，0.0、0.8、1.6、2.4% BW 和禁闭治疗的皮下脂肪厚度增加分别为 0.25、0.74、1.61、1.69 和 1.98。相反，处理对肉的物理化学特性没有影响，都被认为是适度柔软、多汁（嫩）、味道和气味温和。臂形牧场饲养的羔羊肉质优良，但需要补充更多的蛋白质能量，才能成为幼小动物饲养场的替代品。
