Abstract
Este estudio se propuso evaluar el efecto del hongo Pleurotus ostreatus, cultivado en residuos orgánicos agroindustriales, sobre los parámetros productivos y sensoriales de pollos de engorde Cobb 500. Se utilizaron tres sustratos: coronta de maíz (CM), cascarilla de arroz (CA) y bagazo de caña de azúcar (BC). Se aplicó un diseño de mezcla simplex compuesto (DMSC) para determinar la eficiencia biológica (EB) y rendimiento (R) de la producción del hongo. Posteriormente, para la crianza de 48 pollos, se utilizó un DCA, de 4 tratamientos (sustitución de alimento balanceado por hongo al 0% (T0); 5% (T1); 10% (T2) y 15% (T3)) y 3 repeticiones (4 pollos por repetición), para evaluar parámetros productivos y calidad sensorial. Los resultados mostraron que la combinación óptima de sustratos fue CM y BC, logrando una EB del 28,50% ± 0,95 y un R de 1,91% ± 0,01. El tratamiento T1 (5% de sustitución) presentó el mayor peso corporal a los 44 días (2953,3 ± 92,44 g) y la mejor ganancia diaria de peso en 32 días (100,89 ± 2,50 g). Mediante prueba CATA se identificaron, en el pollo sancochado, atributos definidos y relacionados entre los tratamientos T0, T1 y T2. No se identificó diferencias significativas en aceptabilidad general entre los tratamientos, con un nivel de “Me Gusta”.
This study aimed to evaluate the effect of the fungus Pleurotus ostreatus, grown on agro-industrial organic wastes, on the productive and sensory parameters of Cobb 500 broilers. Three substrates were used: corn stover (CM), rice husk (CA) and sugarcane bagasse (BC). A compound simplex mixture design (CSMD) was applied to determine the biological efficiency (BE) and yield (Y) of the fungus production. Subsequently, for the rearing of 48 chicks, a DCA of 4 treatments (replacement of balanced feed with fungus at 0% (T0); 5% (T1); 10% (T2) and 15% (T3)) and 3 replicates (4 chicks per replicate) was used to evaluate productive parameters and sensory quality. The results showed that the optimum combination of substrates was CM and BC, achieving an EB of 28.50% ± 0.95 and an R of 1.91% ± 0.01. Treatment T1 (5% substitution) presented the highest body weight at 44 days (2953.3 ± 92.44 g) and the best daily weight gain in 32 days (100.89 ± 2.50 g). By means of the CATA test, defined and related attributes were identified in the parboiled chicken between treatments T0, T1 and T2. No significant differences in general acceptability were identified between treatments, with a level of “I like it”.
