The objective was to investigate the effects of increasing levels of extruded urea (EU) in the supplementation of lambs grazing. Crossbred Texel lambs (n = 45) were used and kept in continuous grazing in paddocks with Brachiaria spp. The design used was completely randomised, with five of EU replacing soybean meal (0; 6; 12; 18 and 24 g/kg) and two sexes (male and female). The animals were slaughtered, and qualitative and quantitative evaluations of the carcass, non-carcass components, meat quality and chemical composition were carried out. There was an interaction between level*sex for ether extract (EE) and crude protein (CP), so than the meat of the females from the treatment without EU had a higher content of EE than that used EU and the meat of the males from the treatments with 12 g and 24 g 100 kg−1 LW higher levels of CP than other treatments. For all measurements performed up to 18 g 100 kg−1 LW of EU replacing bran and soy, the results were promising, and can be fed to finishing lambs under grazing, without negatively influencing most of the carcass characteristics, components non-carcass, meat quality and chemical composition.
