Enzymes are biological catalysts that accelerate chemical reactions in the body. In feed nutrition, enzymes are used to break down complex molecules into simpler ones, making them more easily digestible by animals. Enzymes are more efficient than chemical additives because they work at lower temperatures and pH levels, reducing the energy required to break down food. Additionally, enzymes are eco-friendly because they are biodegradable and do not leave harmful residues in the environment. Chemical additives, on the other hand, can be toxic and have negative environmental impacts. Therefore, enzymes are a safer and more sustainable alternative to chemical additives in feed nutrition.
