Bandinha de feijão (Phaseolus vulgaris L.) em alimento seco extrusado para cães

Abstract

Beans have emerged as a viable and appropriate alternative source of crude protein, carbohydrates, and fiber in the diets of dogs and cats. However, there is a need to establish evidence- based parameters regarding the incorporation of bean pod husks into dog food formulations to ensure their nutritional effectiveness and safety. This is crucial for enabling their quality industrial production, given that beans contain antinutritional factors that could be harmful to dogs. This study aimed to evaluate the use of beans (Phaseolus vulgaris L.) at 10%, 20%, and 30% compared to the control diet in feeding dogs. The extrusion process effectively reduced tannins, phytic acid, and trypsin inhibitor, lowering the antinutritional factors to <0.001%, 0.70%, and 2.0 UIT/mg, respectively. Palatability and acceptability tests showed no significant differences between the diets. Fecal score worsened with the inclusion of 30% compared to the control diet. Digestibility coefficients of crude protein, ether extract, and metabolizable energy decreased with 30% inclusion of bean pod husks. The animals remained healthy throughout the experiment, and blood analyses (complete blood count, urea, and creatinine) stayed within the reference range. Therefore, it is concluded that it is safe to include bean pod husks in up to 20% of dogs' diets.
