Abstract The study will be developed in the Ovine Production Laboratory of the Department of Animal Science, College of Agricultural and Veterinarian Sciences, São Paulo State University, Jaboticabal, SP, Brazil. Thirty Ile de France lambs, not castrated, with 15 kg of body weight will receive diets without and with 10 and 20% of crude glycerin, in partial substitution to corn, being the roughage sugarcane in natura variety IAC 86-2480, with roughage:concentrate ratio 50:50. The objectives are to evaluate the meat quality parameters (pH, temperature, color, water holding capacity, sarcomere length, cooking losses, shear force, water loss by defrosting, number of substances reactive to 2-thiobarbituric acid and sensory analysis), the centesimal composition (moisture, crude protein, fat and mineral matter),the fatty acid profile and cholesterol content of meat from Triceps brachii, Semimembranosus and Longissimus lumborum muscle, from early, intermediate and late developments, respectively. The experimental design will be completely randomized with three treatments and ten replicates, being the comparisons of the treatments by orthogonal contrasts with the assistance of the SAS statistical program (2003). | |
