What is the role of chemical preservatives in animal feeds?

• A. To enhance flavor
• B. To extend shelf life and prevent spoilage
• C. To increase crude protein content
• D. To neutralize toxins

Answer: (B)

Chemical preservatives in animal feeds are used to extend shelf life and prevent spoilage by inhibiting microbial growth and slowing oxidation. Stored feeds can spoil due to molds, bacteria, yeast, and fat rancidity, especially in warm, humid conditions. Preservatives such as organic acids (like propionic, sorbic, and benzoic acids) and antioxidants help keep the feed stable, protecting its nutritional value and palatability over time. They aren’t intended to enhance flavor, raise crude protein, or neutralize toxins, which are not the roles of preservatives.
