The pork producers around the world must efficiently produce the quality lean pork that consumers demand to remain competitive. Hence, lean growth rate, lean efficiency, and total production cost per unit of lean meat are the important traits for the future. Efficient growth is dependent on many factors, out of which, nutrition is very important since it can also influence the rate of deposition of lean meat if supplemented accurately.

Metalean is a protein optimizer that improves protein synthesis by affecting the protein turnover rates. Supplementing the diets with Metalean not only helps pigs to retain more protein but also lower nitrogen excretion and improves nitrogen efficiency.
