Which nutrient is essential for muscle growth in livestock?

Proteins are essential for muscle growth in livestock because they are crucial components in the formation of muscle tissue. When livestock consume protein, their bodies break it down into amino acids, which are the building blocks necessary for synthesizing new proteins in the muscles. This process is vital for growth, repair, and the overall maintenance of muscle health in animals.

Additionally, proteins play a significant role in various metabolic processes, contributing to the production of enzymes and hormones, which also influence muscle development and function. While other nutrients such as carbohydrates, fats, and minerals do have important roles in an animal's overall health and energy metabolism, it is the amino acids derived from proteins that directly support muscle growth and development.
