The increasing interest in natural feed additives reflects a strategic shift toward safer and more sustainable livestock production. Herbal supplements such as plant extracts, essential oils, probiotics, and phytogenic compounds have demonstrated considerable potential to enhance animal health, support gut microbiota balance, and boost productivity, all while reducing reliance on synthetic additives and antibiotics. Moreover, these natural additives play a significant role in improving the quality, safety, and consumer appeal of animal-derived products, including meat, milk, and eggs. Despite these promising benefits, further research is still needed to clarify their mechanisms of action, determine optimal dosages, and improve their bioavailability across various animal species and production systems. This evolving field holds substantial promise for driving forward eco-friendly and health-conscious livestock production.
