Abstract

Microalgae have garnered a considerable attention as a sustainable substitute as customary feed ingredients for poultry, predominantly due to their extraordinary nutritive profile and purposeful properties. These minuscule organisms are protein rich, retain an ample quantity of essential fatty acids, vitamins, minerals, and antioxidants, thus are capable of improving nutritive value of poultry diets. Microalgae comparatively delivers an outstanding source of protein containing substantial amount of innumerable bioactive complexes, omega-3 fatty acids in addition to the essential amino acids (methionine and lysine), crucial for optimal growth and development. Besides nutritional significance, microalgae have considerable immunomodulatory and antioxidant properties that help to reduce oxidative stress and enhance immune status, thereby improving the overall health and performance. Additionally, microalgae proved to induce antimicrobial and intestinal health benefits via upregulated gut eubiosis, promoting the colonization and growth of probiotic bacteria and offering protection against infections. These nutraceutical benefits are particularly important for sustainable poultry production and reducing the dependence on antibiotic growth promoters to produce antibiotic free food. This review aims to highlights multifaceted advantages of microalgae as a functional feed additive for poultry diet to support sustainable and efficient poultry production.
