Which nutrient is essential for muscle development in livestock?

1. Carbohydrates

2. Proteins

3. Fats

4. Vitamins

The correct answer is: Proteins

Proteins are essential for muscle development in livestock because they provide the necessary amino acids that serve as the building blocks for muscle tissue. Livestock, like all animals, rely on protein to develop and maintain their muscles, especially during growth phases or when energy needs are higher due to physical activity. Unlike carbohydrates and fats, which serve primarily as energy sources, proteins play a direct role in growth and repair of tissues. They are crucial not only for muscle growth but also for overall developmental processes in livestock, contributing to functions such as immune response and hormone production. While vitamins are important for various metabolic processes, they do not directly contribute to muscle mass like proteins do. Thus, in the context of muscle development, the significance of proteins cannot be overstated. They are fundamental to achieving optimal growth and production in livestock.
