Evaluación de la capacidad de secuestro de la bentonita sódica en aflatoxinas B1 de Aspergillus spp, presente en el alimento balanceado para pollos preiniciadores en el norte de la ciudad de Guayaquil.

Abstract

Mycotoxins, present in feed used by poultry industries, are an important subject of study and one of the greatest concerns due to the damage they cause to animals, to producers and companies in the poultry sector due to the reduced chicken performance. As there is no efficient technique for the elimination of aflatoxins, the impact of the addition of a sequestrant or adsorbent was evaluated using sodium bentonite as a base in the nutrition of pre-starter chickens, in order to reduce the absorption in the intake and reduce the effects of aflatoxins. The investigative approach was exploratory, experimental, descriptive, quantitative and correlational. Two types of experiments were performed. Four unprocessed food bases were used, and each was combined with the product based on sodium bentonite, for further analysis. An enzymatic digestion of poultry was simulated for the adsorption of aflatoxins by sodium bentonite, and thus to know its effect through a spectrophotometric analysis. Which would counteract the sequestration capacity of bentonite in each of the foods. For the second type of experiment, the methodology of connected matrices was applied, a simulated experimentation was carried out, the restrictions were entered in their respective units with the limits, forming a 4 x 24 matrix. It was determined that the suggested dose is: 0.0025 % to 0.005 %.
