Feed additives have become an integral part of modern livestock production, aiming to enhance animal health, improve productivity, and ensure the safety and quality of animal-derived products. This review comprehensively examines the impact of various feed additives on the quality and shelf life of livestock products, including meat, milk, and eggs. The focus is on the role of additives such as probiotics, prebiotics, enzymes, antioxidants, organic acids, and phytogenic compounds in improving nutritional value, sensory attributes, and oxidative stability, while extending shelf life by inhibiting microbial growth and lipid oxidation. Feed additives offer promising solutions for sustainable and healthier animal production systems. They also positively affect animal physiology through improved feed digestibility and better growth performance. However, if not properly handled and used, negative outcomes can occur for both animals and the environment. This review concludes that feed additives significantly improve livestock product quality and shelf life by modulating gut health, reducing oxidation, and inhibiting microbial growth. However, further research is needed to optimize their use, address regulatory challenges, and ensure consumer acceptance.
