The objective of this work was to evaluate the effect of sex and of three finishing systems on sensory traits of Texel × Corriedale lamb meat an on the consumer acceptance of the meat. It was used 90 animals, 45 non-castrated male lambs and 45 females kept on pasture until weaning (70 days of age) and finished in three production systems: pasture, pasture with mother, and pasture with supplementation (soybean hull corresponding to 1% of life weight of the lambs). After slaughter, carcasses were stored in cold chamber, with forced air at 1°C until reaching 24 hours for removal of longissimus dorsi muscle which had been frozen at -18°C for sensory analysis. Meat sensorial characterization was performed by quantitative descriptive analyses: 22 descriptive terms were developed by a team of selected judges who also created the definition for each term and the reference-samples. Acceptability test was performed by using a nine-point hybrid hedonic scale. Meat of male animals and of animals finished in pasture with the mother was characterized by the flavor and softer residual taste sheep meat and fat, less softness and higher chewiness in comparison to the meat of female and of animals finished in the other systems. Meat of lambs finished in pasture systems and pasture with supplementation were similar regarding to sensory aspects. Meat was equally accepted by the consumers, regardless of sex and finishing system, presenting good acceptability. © 2011 Sociedade Brasileira de Zootecnia. Source
