Description

The objective of the present study was to assess the ammonified corn cob (Zea mays L) with three levels of urea in the Urdaneta canton. We worked with three levels of urea (3, 4 and 5%) in the form of an aqueous solution on the corncob stored hermetically in plastic bags for a period of 20 days. The variables dry matter, crude protein (PC%), neutral detergent fiber (NDF%), acid detergent fiber (FDA%) were evaluated, with a completely randomized design with four pulls and three repetitions. The results for the 0, 3, 4 and 5% urea treatments were: According to the analysis of variance (ANOVA), significant differences were obtained between the treatments. With the dose of 0% urea, the highest amount of dry matter was obtained with 89.07%, which was higher than the treatments with 3% (70.28), 4% (68.81) and 5% (67, 86). The Tukey mean comparison test found no significant difference between treatments, numerically the treatment with the best ash averages was the control treatment with 8.50% and the lowest average was found in T2 (corn pan at 4% urea). with 6.56%. The corn panca with a time of 20 days of ammonification and with levels of 3, 4 and 5% of urea dissolved in water, increased the crude protein. 8.0, 10.59 and 12.02%, respectively. While the corn flakes without urea, the crude protein content was 5.79%. The effect of dissolved urea on the cell wall reduced the neutral detergent fiber content. The corn flake without urea 75.29% and with 5% urea was 72.39%. The corn flake with 0% urea was 51.08% and with 5% urea it was reduced by 49.05% in the acid detergent fiber.

El objetivo del presente estudio fue valorar la panca de maíz amonificada (Zea mays L) con tres niveles de urea en el cantón Urdaneta. Se trabajó con tres niveles de urea (3, 4 y 5%) en forma de solución acuosa sobre la panca de maíz almacenada herméticamente en bolsas plásticas durante un periodo de 20 días. Se evaluaron las variables materia seca, proteína cruda (PC%), fibra detergente neutro (FDN%), fibra detergente acida (FDA%), con un diseño completamente al azar con cuatro tiramientos y tres repeticiones. Los resultados para los tratamientos 0, 3, 4 y 5% de urea fueron: De acuerdo con el análisis de varianza (ANOVA), se obtuvieron diferencias significativas entre los tratamientos. Con la dosis de 0% de urea se obtuvo la mayor cantidad de materia seca con 89,07%, que fue superior a los tratamientos con 3% (70,28), 4% (68,81) y 5% (67,86). La prueba de comparación de medias Tukey no encontró diferencia significativa entre tratamientos, numéricamente el tratamiento con mejores promedios de cenizas fue el tratamiento testigo con 8,50% y el menor promedio se encontró en el T2 (Panca de maíz al 4 % de urea) con 6,56%. La panca de maíz con un tiempo de 20 días de amonificación y con niveles de 3, 4 y 5% de urea disuelta en agua, incremento la proteína cruda. 8.0, 10.59 y 12.02%, respectivamente. Mientras que la panca de maíz sin urea, el contenido de proteína cruda fue de 5,79%. El efecto de la urea disuelta sobre la pared celular redujo el contenido de fibra detergente neutro. La panca de maíz sin urea 75.29% y con urea al 5% fue de 72.39%. La panca de maíz con 0% de urea fue de 51.08% y con urea al 5% se redujo en 49.05% en la fibra detergente acida.
