DL-Alanyl-DL-methionine is primarily used as a feed additive in animal nutrition, particularly in poultry and livestock. It serves as a source of essential amino acids, helping to improve protein synthesis and overall growth performance. The compound is also utilized to enhance feed efficiency, ensuring that animals receive adequate nutrition even with lower-quality feed. Additionally, it supports liver function and detoxification processes in animals, promoting better health and productivity. In aquaculture, it is incorporated into fish diets to boost growth rates and improve feed conversion ratios. Its role in providing methionine, a limiting amino acid, makes it crucial for optimizing animal diets and ensuring balanced nutrition.
