Sumario:The cottonseed cake has the necessary nutritional characteristics to be able to substitute the traditional ingredients (such as soybean meal) and reduce the costs of the diet. However, it is necessary to determine the best level of inclusion of cottonseed cake in the diets of fattening goats to improve meat production and quality. The objective of this study was to evaluate carcass and meat traits of feedlot goats fed diets containing cottonseed cake replacing soybean meal (33 %, 66 % and 100 %). Thirty-two uncastrated Boer crossbred goats (4 months old, 16  [Formula: see text]  2 kg initial body weight) were used in a completely randomized experimental design. Replacing soybean meal with cottonseed did not compromise ([Formula: see text]) slaughter weight, carcass traits (dressing percentage, loin-eye area and back-fat thickness), primal cuts or carcass morphometric measurements; moisture, protein, or total lipid contents of meat; or the physicochemical traits of color ([Formula: see text] , [Formula: see text] and [Formula: see text] coordinates), pH, shear force, and cooking loss. However, there was a reduction ([Formula: see text]) in the mineral matter content (from 1.08 % to 0.97 %) and an increase ([Formula: see text]) in the cholesterol content (from 50.85 to 70.55 mg/100 g of meat) of the meat as the dietary levels of cottonseed cake were increased. Based on the results of production and meat quality, we recommend using cottonseed cake as an alternative protein source to replace up to 100 % of soybean meal in feedlot goat diets.
