Resumo: | ABSTRACT The objective of this study was to evaluate the oxidative stability of cashew nut meal (CNM) at 180 days of storage and the effects of its use in the feed of meat quails. A total of 280 animals at seven days of age, of both sexes, were distributed in a completely randomized design with five treatments, in a 2 × 2 + 1 factorial arrangement, and seven replicates of eight birds each. The treatments were a control diet without CNM and diets containing levels of 12.5 or 25% of new CNM (NCNM) or stored for 180 days (SCNM). The lipid oxidation of the brans was evaluated by determining the acidity index and peroxide index. The parameters evaluated were the quail performance, metabolizable coefficients and energy of diets, carcass characteristics, relative weights of the liver and pancreas, and bone parameters. The acidity of cashew nut meal was 4.66% and 6.16 (% in oleic acid) for NCNM and SCNM, respectively. Independent of the storage, inclusion of CNM resulted in higher metabolizable energy values in the diet, reduced intake, and, because weight gain did not vary, feed conversion improved compared with the control treatment. Carcass traits, relative weights of liver and pancreas, as well as bone growth and quality were not affected by dietary treatments. Despite the hydrolytic rancidity, CNM can be used in the diets for meat quails at up to 25% of inclusion.
