Efecto de la suplementación con fitasas en la dieta de codornices de producción de huevos

The Ecuadorian poultry sector, particularly quail egg production, faces challenges related to nutritional efficiency and environmental sustainability, especially concerning the availability of phosphorus present in the form of phytates. This study aimed to evaluate the effect of phytase supplementation in the diet of 160 laying quails (Coturnix japonica), randomly distributed into four treatments: a control group without phytase and three groups supplemented with 40, 45, and 50 g/t of solid phytase. A completely randomized design was used, along with analysis of variance (ANOVA), Tukey tests, and bromatological evaluations to determine the nutritional quality of the eggs and the phosphorus and nitrogen concentrations in the feces. The results showed that the inclusion of phytase at 45 g/t resulted in the highest daily egg production and the greatest protein content, while the 50 g/t dose was most effective in reducing fecal phosphorus and nitrogen excretion, thus decreasing the environmental load. Furthermore, all supplemented treatments improved parameters such as fat and fiber, enhancing the nutritional value of the eggs. These findings confirm that phytase is an effective biotechnological tool for optimizing nutrient digestibility, improving productive efficiency, and reducing the environmental impact of quail production. It is concluded that enzymatic supplementation not only enhances productive performance and egg quality but also promotes more sustainable and economically viable poultry practices within the Ecuadorian context.
