Evaluation of dry diet with ensilage of meat by-products for intensive cultivation of Clarias gariepinus.Abstract
Un total de 240 alevines de Clarias gariepinus de 7,0 g ± 0,02 g de peso medio, se utilizaron para evaluar una dieta seca con ensilado químico de subproductos de cerdos como alternativa de los alimentos comerciales SKRETTING para el cultivo intensivo de bagres. Los peces se distribuyeron según diseño experimental completamente aleatorizado en dos tratamientos con tres repeticiones y se alimentaron durante 60 días. Se encontraron diferencias significativas (p < 0,001) en los indicadores de consumo de alimento (49,01 g/pez y 42,78 g/pez), crecimiento (pesos finales de 51,14 g y 60,64 g) y conversión alimentaria (1,12 y 0,85) a favor de los piensos SKRETTING, que se corresponde con su alta calidad nutricional y tecnológica. Sin embargo, las supervivencias fueron similares (91,67 % y 92,92 %) para ambos tratamientos. El costo de la ración experimental fue US $ 0,925 / kg, respecto a los alimentos del control (US $ 2,45; 1,64 y 1,61). Se evidenció la potencialidad de los ensilados de subproductos cárnicos como sustituto parcial de la harina de pescado en raciones secas con altos niveles de proteínas para los cultivos intensivos de bagres africanos y se sugiere continuar las investigaciones por un período mayor.A total of 240 of Clarias gariepinus fingerling (7,0 g ± 0,02 g average weight) was used to evaluate a dry diet with by-products of pigs chemical silage like alternative of commercial foods SKRETTING for the intensive culture of catfish. Fish were distributed according to completely random design in two treatments with three repetitions and were feeding during 60 days. The results showed significant differences (p < 0,001) in indicators food consumption (49,01 g/fish and 42,78 g/fish), growth (final weight of 51,14 g and 60,64 g) and feed conversion rate (1,12 and 0,85) in favor of SKRETTING food by their high nutritional and technological quality. However, survival rate were similar (91,67 % and 92,92 %) for both treatments. The cost of the experimental ration was US $ 0,925/kg regarding foods of control (US $2,45; 1,64 and 1,61). The potentiality of meat by-products silage was evidenced as partial substitute of fish meal in dry rations with high levels of protein for intensive culture of african catfish and it is suggested to continue the investigations for a bigger period.
