Abstract: Physic nut Jatropha curcas cake/meal obtained after oil extraction has a high protein content, however, the presence of antinutrients (trypsin inhibitor, lectin and phytate) and toxic compounds (phorbol esters) limit their use as an alternative feedstuff. Thus, the detoxification process in cake/meal is necessary to allow their inclusion in fish diets. The present study aimed to evaluate the effects of solvent and extrusion-treated jatropha cake (SETJC) in Nile tilapia (Oreochromis niloticus) diets on growth, body composition, nutrient utilization, metabolic and hematological responses, and digestibility of experimental diets. Five experimental diets were formulated to be isonitrogenous (28.50% digestible protein) and isoenergetic (13.39 MJ/kg digestible energy) with graded levels of SETJC (0, 3, 6, 9, and 12%). The experimental design was completely randomized with five treatments and four replicates. The detoxification treatments reduced the phorbol esters (PE) of jatropha cake by 96% (0.58 mg/g of PE before and 0.023 mg/g of PE after treatments). Increased levels of SETJC depressed growth, feed efficiency, and protein digestibility. A similar trend was observed for hematological and biochemistry parameters. Aspartate and alanine aminotransferase, as well as phosphorus and magnesium concentrations in the fillets, increased at the highest levels of SETJC. Thus, the data of the present study suggests that the residual content, different structural forms of phorbol ester and its biological activity, as well as some antinutritional factors, can influence negatively the growth, metabolism and digestibility of experimental diets for Nile tilapia.
