Abstract
The objective of this study was to evaluate the replacement of soybean meal by soybean cake on carcass characteristics and meat quality of Santa Ines lambs. Twenty-nine intact males were used, weighing 23.63 ± 2.44 kg, at 80 days of age, distributed randomly, submitted to five diets, with the diets differing in the levels of substitution of soybean meal by soybean cake (0, 25, 50, 75 and 100%). Each diet was provided to six animals, except the 25% diet, in which five animals were used. Carcass characteristics were evaluated, and the Longissimus dorsi was removed for meat quality analysis. The different levels of soybean cake did not affect carcass characteristics. Regarding the characteristics of meat, there was a quadratic effect for the shear force and negative linear effect on flavor intensity, but no significant differences on the other parameters were observed. Replacement of soybean meal for soybean cake can be made without affecting most of the carcass and meat characteristics, and high levels of soybean cake in the diet can improve the meat sensorial quality of lambs receiving concentrated diets.
