Why is the breakdown of proteins a problem from animals?

The breakdown of proteins in animals can lead to various health issues, such as muscle wasting and impaired immune function, as essential amino acids are not adequately supplied. This process can result from factors like malnutrition, disease, or metabolic disorders, ultimately affecting the overall health and productivity of the animal. Additionally, the accumulation of toxic byproducts from protein breakdown can further exacerbate health problems. Ensuring proper protein metabolism is crucial for maintaining the well-being of animals.
