- Characterization and Digestibility of Detoxified Castor Oil Meal for Japanese Quails PA dos Santos MCMM Ludke JV Ludke CBV Rabello MJB dos Santos TR Torres Agrociencias energy poultry cytotoxicity digestibility Alternative food These experiments were performed to determine the chemical composition, coefficients of nutrient and energy metabolizability, amino acid composition, and cytotoxicity of different castor oil meals subjected to different detoxification processes and added to the diet of Japanese quails. In the trial, 180 46-d-old female Japanese quails were distributed according to a completely randomized design into five treatments and with replicates of six bird each. The treatments consisted of following detoxification methods of castor oil meal: Castor oil meal A (CMA) - recovery in alcohol at 80 °C for 20 minutes and drying at 80 °C; castor oil meal B (CMB) and C (CMC) - recovery in alcohol at 80 °C for 6 minutes, neutralization with 5% NaOH, and drying under direct sunlight sun for two days (CMB) or pelleted (CMC); castor oil meal D (CMD) - recovery in alcohol at 110 °C for 15 minutes and drying at 110 °C. Castor oil meal was added replacing 20% of the reference diet. There was slight chemical composition variation (1.21% in crude protein, 6% in dry matter, 2.2% in ether extract and 64 kcal/kg in gross energy) among the castor oil meals submitted to the different treatments. The castor oil meal submitted to treatment C showed the highest amino acid values. In the cytotoxicity test, treatment D presented lower ricin activity. Castor oil meals A, C, and D may be included in Japanese quail diets; however, castor oil meal D is recommended due to the simplicity its industrial process, its low toxicity, and metabolizability coefficients obtained. 2015 artículo científico 1516-635X https://www.redalyc.org/articulo.oa?id=179743513009 en http://www.redalyc.org/revista.oa?id=1797 Revista Brasileira de Ciência Avícola application/pdf Fundação APINCO de Ciência e Tecnologia Avícolas Revista Brasileira de Ciência Avícola (Brasil) Vol.17
