Which nutrient is vital for muscle development in livestock?

1. Carbohydrates

2. Fats

3. Protein

4. Vitamins

The correct answer is: Protein

Protein is essential for muscle development in livestock because it serves as the primary building block for muscle tissues. Livestock, like other animals, require protein to repair and grow muscle fibers, which is crucial for their overall growth, body condition, and productivity. When livestock consume protein, it is broken down into amino acids, which are then utilized to synthesize new proteins in the body, contributing to muscle growth and repair. In the context of animal nutrition, while carbohydrates and fats also play important roles—such as providing energy for physical activity and supporting various metabolic functions—they are not directly responsible for muscle development to the same extent as protein. Vitamins, on the other hand, are essential for overall health and biological processes but do not serve as the primary components necessary for building muscle tissue. Therefore, in terms of muscle development specifically, protein stands out as the vital nutrient for livestock.
