Carbohydrate-active enzymes in animal feed


Considering an ever-growing global population, which hit 8 billion people in the fall of 2022, it is essential to find solutions to avoid the competition between human food and animal feed for croplands. Agricultural co -products have become important components of the circular economy with their use in animal feed. Their implementation was made possible by the addition of exogenous enzymes in the diet, especially carbohydrate -active enzymes (CAZymes). In this review, we describe the diversity and versatility of microbial CAZymes tar-geting non-starch polysaccharides to improve the nutritional potential of diets containing cereals and protein meals. We focused our attention on cellulases, hemicellulases, pectinases which were often found to be crucial in vivo. We also highlight the performance and health benefits brought by the exogenous addition of enzymatic cocktails containing CAZymes in the diets of monogastric animals. Taking the example of the well-studied commercial cocktail RovabioTM, we discuss the evolution, constraints and future challenges faced by feed en-zymes suppliers. We hope that this review will promote the use and development of enzyme solutions for in-dustries to sustainably feed humans in the future.
