Efecto de la inclusión de grasa amarilla en el alimento balanceado sobre los parámetros de la canal y vísceras en pollos broiler en la granja Santa Inés.

Abstract

This research study was conducted at the "Santa Inés" experimental farm of the Faculty of Agricultural Sciences of the Technical University of Machala, El Oro Province, Ecuador. The objective was to evaluate the effect of including yellow fat in feed on carcass and viscera parameters in broiler chickens. Two hundred chickens were randomly distributed across five treatments with four replicates. Each treatment included different percentages of yellow fat in the diet (0%, 25%, 50%, 75%, or 100%). The variables studied were: Antemortem weight (g), Bleeding weight (g), Plucking (g), Evisceration (g), Carcass yield (%), Breast (g), Thighs (g), Drumsticks (g), Shoulder (g), Head (g), Neck (g), Legs (g), Wings (g), Heart (g), Spleen (g), Liver (g), Gizzard (g), Intestines (g), Gizzard fat (g), and Abdominal fat thickness (mm). Data were analyzed using ANOVA and the Kruskal-Wallis test. Results indicated that the inclusion of yellow fat does not significantly affect carcass or viscera parameters in broiler chickens. It is concluded that this practice is feasible and profitable, especially in contexts where the price of palm oil is high, thus favoring the profitability of producers and contributing to the sustainability of the poultry sector.
