Abstract
Enzyme technology has emerged as a core component of modern animal nutrition, offering practical solutions to improve feed utilization, enhance digestive efficiency, and support sustainable livestock production. This review synthesizes current advances in the application of exogenous feed enzymes in animal diets, with emphasis on their contribution to improved nutrient digestibility, bioavailability, and overall feed efficiency. Key enzymes, including phytases, proteases, carbohydrases, and lipases, are widely utilized to degrade anti nutritional factors and complex feed constituents that are poorly utilized by monogastric and ruminant animals. Their incorporation into feed formulations enhances the breakdown of indigestible substrates, resulting in improved energy release and nutrient absorption. The review further discusses the biochemical mechanisms underlying enzyme activity, including substrate specificity and synergistic interactions, as well as their influence on gut microbiota composition, intestinal integrity, and metabolic efficiency. Species specific responses across poultry, swine, and ruminants are highlighted, reflecting variations in digestive physiology that affect enzyme efficacy and nutrient utilization patterns. Recent advancements in enzyme engineering, thermostability enhancement, and precision delivery systems are also examined, particularly in relation to improving enzyme stability and performance under diverse feed processing and environmental conditions. Despite significant progress, challenges remain related to enzyme compatibility, optimal dosing strategies, and cost effectiveness in commercial production systems. Emerging research directions include the integration of enzyme technology with nutrigenomics, microbiome modulation, and precision nutrition approaches to achieve more targeted and efficient nutrient utilization. Overall, enzyme technology represents a promising and rapidly evolving field that contributes to improved productivity, reduced environmental impact, and enhanced sustainability in animal agriculture.
