Abstract
El objetivo de la presente investigación fue evaluar el agregado de afrecho de yuca y tusa de maíz como fuentes de fibras insolubles en la alimentación de gallinas ponedoras y su efecto en los parámetros productivos y zootécnicos. La muestra utilizada fue de 300 gallinas Hy Line de 65 semanas de edad. Se aplicó un diseño completamente aleatorizado distribuidos en seis tratamientos: T0 (testigo), T1 (1,5 % de afrecho de yuca), T2 (3 % de afrecho de yuca), T3 (1,5 % de tusa de maíz), T4 (3 % de tusa de maíz) y T5 (mezcla de 1,5 % de cada subproducto). Contaron con diez repeticiones y cinco aves por repetición. Se realizó el análisis de contenido de las fibras insolubles Fibra Ácido Detergente (FDA) y Fibra Detergente Neutra (FDN) y las variables productivas peso de las aves, consumo de alimento, porcentaje de producción, peso de huevos y conversión alimenticia. Los resultados muestran que la tusa de maíz tiene un mayor contenido (FDA) con 53,26% y (FDN) con 12,57%, con referencia a los parámetros productivos; el peso de huevos fue mayor para T3 en la semana 3 con 65,33+-0,38, el consumo de alimento y la conversión alimenticia disminuyeron significativamente en semana 3 con 100,18+-2,64 y semana 2 con 1,55+-0,04 respectivamente, mientras que el peso de las gallinas y el porcentaje de producción no se vieron afectados por la inclusión de fibras. Se concluye que, la adición de fibras insolubles en la dieta de ponedoras ha demostrado disminuir tanto el consumo total de alimento como la conversión alimenticia, por lo que se constituye en una alternativa para reducir costos y obtener mayor rentabilidad.
The objective of the present research was to evaluate the addition of cassava bran and corn cob as sources of insoluble fibers in the feeding of laying hens and their effect on productive and zootechnical parameters. The sample used was 300 Hy Line hens of 65 weeks of age. A completely randomized design was applied distributed in six treatments: T0 (control), T1 (1.5% cassava bran), T2 (3% cassava bran), T3 (1.5% corn cob), T4 (3% corn cob) and T5 (mixture of 1.5% of each by-product). They had ten repetitions and five birds per repetition. The analysis of the content of the insoluble fibers Acid Detergent Fiber (ADF) and Neutral Detergent Fiber (NDF) and the productive variables weight of the birds, feed consumption, production percentage, egg weight and feed conversion were carried out. The results show that the corn cob has a higher content (ADF) with 53.26% and (NDF) with 12.57%, with reference to the productive parameters; the weight of eggs was higher for T3 in week 3 with 65.33+-0.38, feed consumption and feed conversion decreased significantly in week 3 with 100.18+-2.64 and week 2 with 1.55+-0.04 respectively, while the weight of the hens and the percentage of production were not affected by the inclusion of fibers. It is concluded that the addition of insoluble fibers in the diet of laying hens has been shown to decrease both total feed consumption and feed conversion, so it constitutes an alternative to reduce costs and obtain greater profitability.
