Tríceps brachii muscle from non-castrated ½ Ile de France ½ Santa Inês lambs terminated in confinement was used for physical and chemical analyses. In natura and roast meat moisture, protein, fat, ashes, carbohydrates, and meat yield were determined after the cooking process. Roast meat presented higher fat and protein values (7,49 and 33,67%), compared to in natura meat (5,36 and 18,85%), respectively. Ashes and carbohydrates percentages were not influenced by the treatments studied; however, in natura meat presented higher moisture values than roast meat (74,05 and 57,02%, respectively). Roast meat presented losses of 33, 20, 1,36, and 35,20% from evaporation, dripping, and cooking during its preparation, respectively. We concluded that roast meat presents higher nutritional value than in natura meat for fat and protein contents because in natura meat presents higher moisture value than roast meat, so roast meat presents higher fat and protein concentration. Meat preparation resulted in cooking losses of 35,20% from dripping and evaporation.
