How can excessive protein in diets negatively affect animals?

Excessive protein in diets can indeed lead to increased nitrogen excretion and environmental pollution. When animals consume protein beyond their needs, the surplus amino acids are broken down, and nitrogen is released as a waste product. This nitrogen is primarily excreted in urine, and when it enters the environment, it can contribute to problems such as waterway pollution, algal blooms, and other issues associated with nutrient runoff.

In many production systems, particularly intensive animal agriculture, managing nitrogen waste is crucial for both environmental stewardship and compliance with regulations. High levels of nitrogen in the environment can disrupt local ecosystems, making it essential to balance livestock diets in a way that optimizes nutrient use while minimizing waste.

This understanding emphasizes the importance of formulating diets that meet but do not excessively exceed the protein requirements of animals, ensuring sustainability and promoting animal health.
