| dc.description | Exogenous enzymes improve bird nutrition through phytate degradation releasing phosphorus and minerals. The main function is to access the cell walls of the fibrous ingredients and release the nutrients that are encapsulated, thus making them accessible, increasing the availability of nutrients and reducing microbial proliferation. The research was carried out with the objective of evaluating the effect of the use of phytase in the feeding of laying hens. The research methodology was carried out through a bibliographic review in scientific journals, books, articles published on websites. Inductive, deductive and analysis methods are used. According to data published by the National Institute of Statistics and Censuses INEC (2021) in the Survey of Surface and Continuous Agricultural Production (ESPAC): "In the poultry sector, 7.8 million birds were registered that are raised in the field, which represents 82.9% and 37.8 million in poultry farms shows 17.1%". the inclusion of phytase, in doses of 350 or 450 U/kg, increases the bioavailability of vegetable phosphorus, which guarantees an adequate supply of Pd (0.26 and 0.32%), sufficient for optimal productive performance and increase in egg weight. supplementation of 60 ppm of phytase enzyme in diets of Isa Brown laying hens from 58 to 67 weeks of age improved flock uniformity based on live weight. Phytase represents an alternative for poultry producers, because including this enzyme, cheaper ingredients can be used in the diet, which allow lower costs without affecting the productive behavior of laying hens and the environment. | es_ES |

| dc.description.abstract | Las enzimas exógenas mejorar la nutrición de las aves a través de la degradación del fitato liberando fosforo y minerales. La función principal es acceder a las paredes celulares de los ingredientes fibrosos y liberar a los nutrientes que se encuentran encapsulados, logrando así que estos sean accesibles incrementando la disponibilidad de nutrientes y reduciendo la proliferación microbiana. La investigación se realizó con el objetivo de evaluar el efecto del uso de fitasa en la alimentación de gallinas ponedoras. La metodología de la investigación se realizó a través de una revisión bibliográfica en revista científicas, libro, artículos publicados en sitios web. Se utilizo los métodos inductivos, deductivos y de análisis. Según datos publicados por el Instituto Nacional de Estadística y Censos INEC (2021) en la Encuesta de Superficie y Producción Agrícola Continua (ESPAC): “En el sector avícola se registraron 7.8 millones aves que son criadas en campo lo que representa el 82,9 % y 37.8 millones en planteles avícolas muestra el 17,1%”. la inclusión de fitasa, en dosis de 350 ó 450 U/kg, aumenta la biodisponibilidad del fósforo vegetal, lo que garantiza un adecuado aporte de Pd (0.26 y 0.32 %), suficiente para un óptimo comportamiento productivo e incremento en el peso del huevo. la suplementación de 60 ppm de enzima fitasa en dietas de gallinas en postura Isa Brown de 58 a 67 semanas de edad mejoró la uniformidad de la parvada en base a peso vivo. la fitasa representa una alternativa para los productores avícolas, debido a que incluyendo esta enzima se pueden utilizar ingredientes en la dieta más económicos los cuales permiten abaratar costos sin afectar el comportamiento productivo de las gallinas ponedoras y el medio ambiente. | es_ES |
