The objective of this study was to evaluate the meat quality of lambs terminated in confinement and fed diets with different concentrate contents. 18 non-castrated ½ Ile de France ½ Santa Inês lambs were used. Their initial weight was approximately 15 kg and they were divided into two separate groups represented by Treatment 1 (T1) - animals fed with diets containing the ratio voluminous:concentrate 35:65 - and Treatment 2 (T2) - lambs fed with diets containing the ratio voluminous:concentrate 65:35 until reaching 32 kg of body weight in confinement, which is the pre-established weight for slaughtering. T1 and T2 lambs presented similar values for pH, shear force, losses due to cooking and water retention capacity; the average values found were 5.70, 1.03 kgf/cm², or 35.20, and 59.31%, respectively. The voluminous:concentrate ratio did not influence the centesimal quality of meat of lambs fed with more concentrated or more voluminous diets for humidity, protein, ethereal extract, and mineral matter. It can be concluded that lambs terminated in confinement fed with different concentrate contents diets presented similar meat quality; therefore, the diet choice depends on the cost of the ingredients at the time of the confinement.
