Feed additives are substances incorporated into animal feed to enhance its quality and the health and performance of animals. These additives, which can be natural or synthetic, serve various purposes such as improving feed efficiency, promoting growth, preventing diseases, and enhancing the quality of animal products like meat, milk, or eggs. Types of feed additives include vitamins, minerals, amino acids, antibiotics, probiotics, prebiotics, enzymes, flavoring agents, preservatives, and antioxidants. The benefits of using feed additives are multifaceted, encompassing improved growth and production, better feed efficiency, disease prevention, enhanced product quality, and cost efficiency. However, the use of these additives is strictly regulated by authorities like the FDA and EFSA to ensure safety for animals, humans, and the environment. Producers must comply with guidelines on the types and quantities of additives used to mitigate any potential adverse effects.
