Addition of Protease Enzyme to Dog and Cat Feed and Its Influence on the Digestibility Coefficient, Immune Response, and Metabolic Biomarkers

Promoting better protein digestibility through exogenous enzymes in the diet is essential in the nutrition of companion animals, mainly for better perfor- mance and maintenance of the animals’ physiological and metabolic systems, promoting health and adequate growth. In addition, it reduces the cost of the diet by possibly reducing protein in the diet, which is the main and most ex- pensive ingredient for dogs and cats. The objective of this study was to verify whether the addition of protease...
