Proteins are essential for the growth and development of young animals due to their crucial role in building and repairing tissues, including muscles, organs, and skin. During critical growth phases, young animals require proteins to provide the amino acids necessary for synthesis of new proteins in their bodies. Proteins serve as the building blocks for all cells and are necessary for the development of the skeletal and muscular systems. Additionally, they play vital roles in enzyme and hormone production, which further supports metabolic processes and overall growth.

While carbohydrates, fats, and vitamins contribute to overall nutrition, they do not primarily drive the physiological processes involved in growth and development in the same way that proteins do. Carbohydrates serve mainly as an energy source, fats provide energy and are involved in cellular structure and function, and vitamins are crucial for various metabolic functions but do not directly promote tissue growth. Thus, proteins stand out as the critical nutrient for young animals' growth and development.
