“Inclusión de harina de cáscara de cacao (Theobroma cacao l) en la dieta: sobre los parámetros productivos y la calidad de la carne (Oreochromis spp)”

This research work was carried out at the facilities of the Piscícola Socio Tilapia Cía. Ltda .; located at km 8.5 via Quevedo, Santo Domingo, in the San Jacinto de Buena Fe canton, Los Ríos province at 0 ° 53 'south latitude and 79 ° 29' longitude, at an altitude of 100 meters above sea level, with the objective of determining the inclusion of cocoa shell flour (Theobroma cacao L) as an alternative protein source for fattening Tilapia (Oreochromis spp) in captivity, and its performance; To do this, 128 tilapia were used in the fattening phase, with 8 experimental units per cage; all these tilapias were used in a completely randomized design with 4 treatments and 4 repetitions, the levels evaluated in inclusion of cocoa shell flour were, (0%, 4%, 8% and 12%) they were fed by space 42 days with commercial pelleted concentrate as a control. Obtaining the following results: tilapia fed with inclusion of 4% and 8% of cocoa shell flour, showed greater utility, and the best responses were found in the diets with greater inclusion of cocoa shell meal, in pelletized diets the parameters evaluated in the biological production of the fish in the productive study of the fish under treatment, therefore it is recommended to include up to 12% of cocoa husk flour in the diets of tilapia in the fattening phase, due to the results obtained, and due to the alternative of lowering feeding costs, presenting an alternative to fish-breeding producers. Keywords: Captivity, cocoa, husk, nutrients, cage, lipids.
