An essential nutrient required in large amounts for livestock growth is?

Proteins are essential nutrients for livestock growth because they serve as the building blocks for muscles, enzymes, and hormones. Livestock use proteins to grow, repair tissues, and maintain body functions. As animals grow and develop, their protein requirements increase significantly, particularly during periods of rapid growth such as weaning, finishing, or during lactation for breeding females.

While carbohydrates also play a crucial role in providing energy, and vitamins and minerals are necessary for various metabolic processes and overall health, proteins are unique in their function as a fundamental component for growth and tissue development. Livestock unable to obtain adequate protein may experience stunted growth, decreased feed efficiency, and impaired immune function, making it clear why proteins are paramount in the diets of growing animals.
