It was aimed to evaluate the effects of replacement of wheat bran in lambs' diets with spineless cactus (0, 33, 66, and 100%) in a lamb's diet on the physicochemical parameters, fatty acids and sensory analyasis of meat. The evaluation utilized 36 loins and legs from F1 ½ Dorper × ½ Santa Inês lambs, with an average initial body weight of 19.5 ± 1.6 kg, were slaughtered after 70 days of confinement. Were found average values of 5.70, 11.27 N, 55.44 mg/100 g, of meat pH, shear force, and cholesterol, respectively. However, stearic acid, linoleic, linolenic, eicosatrienoic and eicosapentaenoic which linearly decreased. The color, aroma, texture, flavor, juiciness and global acceptance of meat were acceptable by the evaluators, additionally, they said they would buy meat coming of animals fed with 100% replacement. It is recommended that wheat bran is replaced by spineless cactus in the diet of lambs when this shows to be an ingredient with better cost-benefit ratio compared to wheat bran.

目的是评估用羔羊日粮中的无脊柱仙人掌（0、33、66和100％）代替羔羊日粮中的麦麸对肉的理化参数，脂肪酸和感官分析的影响。评估使用了来自F1½Dorper×½SantaInês羔羊的36头腰肉和腿，在禁闭70天后，他们的平均初始体重为19.5±1.6 kg。肉的pH，剪切力和胆固醇的平均值分别为5.70、11.27 N，55.44 mg / 100 g。但是，硬脂酸，亚油酸，亚麻酸，二十碳三烯酸和二十碳五烯酸线性下降。评估人员可以接受肉的颜色，香气，质地，风味，多汁性和全球认可度，此外，他们表示，他们将购买用100％替代饲料喂养的动物的肉。
