Efecto de la inclusión de grasa amarilla como sustituto de aceite palma sobre los parámetros productivos de pollos broilers

Abstract

This study was conducted at the Santa Inés experimental farm belonging to the Technical University of Machala, Ecuador, with the aim of evaluating the effect of the inclusion of yellow fat in feed rations for broiler chickens on productive and economic parameters. A total of 200 chickens of the Ross line were used, distributed in five treatments. Each treatment included different percentages of yellow fat (0%, 0.25%, 0.50%, 0.75%, and 1%), with treatment 1 (T1) serving as a control, without yellow fat, and the others with different proportions of it. The variables studied were weekly live weight, weight gain, feed consumption, water consumption, feed conversion ratio (ICA), mortality, productive efficiency factor (FEP), average weight per square meter, average expenses per experimental unit and cost of meat on foot per kilogram. Using a completely randomized design for the experiment. Data were analyzed using ANOVA and the Kruskal-Wallis test. The results showed that yellow fat can partially or fully replace palm oil in broiler feed, without negatively affecting production parameters and with an improvement in production costs. The inclusion of yellow fat is a viable and economic alternative, especially in a context where palm oil prices continue to rise. This study highlights the potential of yellow fat as a nutritional alternative in poultry production, benefiting both the profitability of producers and the sustainability of the industry.
