Abstract
Con el objetivo de evaluar los efectos las dos variedades de Pleurotus sobre la composición nutricional y la digestibilidad in vitro de Zea mays “Panca de maíz”. Se tomaron 15 muestras aleatorias de panca de maíz para cada variedad, provenientes de la ciudad de Trujillo. Los tratamientos fueron: Panca de maíz sin tratar (PMST1), Panca de maíz tratada con Pleurotus ostreatus (PMT1), panca de maíz sin tratar (PMST2) y Panca de maíz tratada con Pleurotus pulmonarius (PMT2). Las variables evaluadas fueron PC, E.E., FC, ELN, cenizas, y FDN. Los resultados obtenidos de PMST1 y PMT1 fueron: 6.03% y 11.82% en PC; 0.41% y 0.45% en E.E., 32.87 % y 23.94 % en FC ; 6.95 % y 8.88 % en cenizas; 51.74 % y 54.91% en E.L.N. ; 84.6% y 55.47% en FDN respectivamente con diferencias estadísticas significativas (p<0.05) entre los tratamientos; en cuanto a la digestibilidad in vitro existió un efecto positivo del PMT1 en comparación con el PMST1, lográndose en PMT1 un 10.58% mayor digestibilidad que el PMST1; Los resultados obtenidos del PMST2 y PMT2 fueron 6.05% y 10.42% en PC; 0.40% y 0.43% en E.E., 32.44 % y 24.45 % en FC ; 6.81% y 8.06 % en cenizas; 51.49 % y 53.48% en E.L.N. ; 83.75% y 59.23% en FDN; en cuanto a la digestibilidad in vitro se logró en el PMT2 un 5.97% mayor digestibilidad que el PMST2; concluyéndose que el tratamiento de panca de maíz con Pleurotus ostreatus y Pleurotus pulmonarius mejora su composición nutricional y su digestibilidad in vitro.
ABSTRACT In order to evaluate the effects of the two varieties of Pleurotus on the nutritional composition and in vitro digestibility of Zea mays “Corn stover ". We took 15 random samples of corn stover for each variety, of the Trujillo city. The treatments were: corn stover untreated (PMST1); corn stover treated with Pleurotus ostreatus (PMT1), corn stover untreated (PMST2) and corn stover treated with Pleurotus pulmonarius (PMT2). The evaluated variables were PC, Ethereal extract, FC, ELN, ashes, and NDF. The results obtained from PMST1 and PMT1 were: 6.17% and 11.82% in PC; 0.41% and 0.45% in E.E., 32.87% and 23.94% in FC; 6.95% and 8.88% in ashes; 51.74% and 54.91% in E.L.N. ; 84.6% and 55.47% in NDF respectively, with significant statistical differences (p <0.05) between treatments; as soon as the in vitro digestibility there was a positive effect of PMT1compared to the PMST1, achieving in PMT1 10.58% greater digestibility than the PMST1; The results obtained from PMST2 and PMT2 were 6.05% and 10.42% in PC; 0.40% and 0.43% in E.E., 32.44% and 24.45% in FC; 6.81% and 8.06% in ashes; 51.49% and 53.48% in E.L.N. ; 83.75% and 59.23% in FDN; as soon as in vitro digestibility was achieved in PMT2: 5.97% greater digestibility than PMST2; It was concluded that the corn stover treatment with Pleurotus ostreatus and Pleurotus pulmonarius improves the nutritional composition and in vitro digestibility.
