SUMMARY:

The objective was to evaluate the tissue composition of the leg, the physical, proximate and sensory analyses of meat from Santa Inês sheep fed with extra-fatty whole corn germ (GIEM) replacing corn, associated with Palma Orelha de Elefante Mexicana (POEM). Forty Santa Inês sheep were used, male non castrated, with an average age of four months and initial weight of 22.0 ± 1.0 kg, distributed in four treatments: POEM + ground corn (MGM), POEM + GIEM, Tifton Grass hay (FCT) + MGM, FCT + GIEM. After 65 days of confinement, the animals were slaughtered and the carcass was cooled in a cold chamber at 4°C for 24h. In the left half carcass, the leg and the longíssimus lumborum were removed for evaluation. Tissue composition and leg muscularity index differed between treatments, with the highest values found in the POEM + GIEM diet. The GIEM associated with cactus in place of corn in the diet of sheep favored the tissue composition of the carcass and the physical quality of the meat of Santa Inês sheep in feedlot. The proximate composition of the semimembranosus muscle showed no significant difference between treatments, indicating that there was no influence of treatments on these parameters. The sensorial analysis of the meat indicated that the characteristics of color, aroma and characteristic flavor were influenced by the treatments, presenting significant differences, while the characteristics of appearance, tenderness, juiciness and strange flavor did not present significant differences in relation to the treatments. The association of extra-fatty whole corn germ can be used in diets for sheep to replace corn and when associated with forage cactus improves the composition and quality of the meat.
