Which nutrient is crucial for muscle growth in livestock?

Proteins are essential for muscle growth in livestock because they are composed of amino acids, which are the building blocks of muscle tissue. Livestock require adequate protein levels in their diet to support the development of muscle mass, especially during growth phases, such as in young animals or those being prepared for market. Proteins are involved not only in muscle synthesis but also play a role in various physiological processes, including hormone production and immune function.

While carbohydrates, vitamins, and fats all play important roles in the overall health and performance of livestock, they do not directly provide the necessary building blocks for muscle tissue. Carbohydrates primarily provide energy, vitamins serve as co-factors in biochemical reactions, and fats contribute to energy storage and absorption of fat-soluble vitamins, but it is proteins that specifically aid in muscle growth and repair.
