What is a common feed additive used in livestock nutrition?

Antibiotics for growth promotion are a common feed additive in livestock nutrition. These substances are administered to animals to enhance growth rates, improve feed efficiency, and prevent certain diseases. By facilitating better nutrient absorption and reducing the incidence of infections, antibiotics can lead to healthier livestock that reach market weight more quickly.

Utilization of antibiotics also helps in managing overall flock or herd health, as healthier animals are less prone to disease, thereby potentially reducing veterinary costs and maximizing productivity. However, their use is subject to regulation in many regions due to concerns about antibiotic resistance and consumer preferences for antibiotic-free products.

Protein supplements are typically used to ensure sufficient protein intake in animal diets but are not classified as growth promoters in the same way as antibiotics. Mineral blocks and vitamins are important for overall animal health and energy levels but do not specifically target growth enhancement as antibiotics do.
