Micelle-Based Phytogenic Compounds in Nonruminant Nutrition: A Review.

Phytogenic feed additives (PFAs) have gained widespread attention in poultry and swine nutrition due to their antioxidant, antimicrobial, and anti-inflammatory properties. However, their practical application is often hindered by poor solubility, low stability, and limited bioavailability. Micelle technology has emerged as an innovative approach to overcoming these challenges by enhancing the solubility, absorption, and efficacy of phytogenic compounds. This review explores the mechanisms of micelle-based delivery systems, highlighting their role in improving nutrient utilization, gut health, and overall animal performance. Specific micelle-encapsulated phytogenic, such as micelle silymarin and micelle quercetin, have demonstrated significant benefits in growth performance, feed efficiency, and oxidative stress reduction in poultry and swine. The potential of micelle technology in reducing antibiotic dependency and mitigating environmental impacts is also discussed. Overall, the integration of micelle-based phytogenic compounds in animal nutrition represents a promising strategy for optimizing productivity, sustainability, and animal welfare in modern livestock production.
