Popis: This study aimed to evaluate the inclusion of detoxified castor meal in the diet of growing goats by the nutritional and productive performance. The study included 36 crossbred Boer goats kids (Boer y Anglo Nubian), with average initial weight of 20 kg ± 3.2 kg, in a completely randomized design with four treatments (diets with inclusion levels of detoxified castor meal of 0, 100, 200 and 300 g per kg dry matter) and nine repetitions. The castor meal was detoxified using calcium oxide in the proportion of 40 g of CaO for each kg of castor meal. Intake, digestibility, performance and metabolic characteristics were evaluated. At the end of the experiment, the animals were slaughtered and eviscerated, and after removal of the head, leather and feet, the carcass weights were measured to obtain the hot carcass weight. From the left half of the carcass, five anatomical regions and sections were individually weighed. The inclusion of detoxified castor meal linearly decreased (P 0.05) by the inclusion of detoxified castor meal. The serum urea levels decreased linearly, and the microbial efficiency increased (P
