Which of the following is a direct purpose of chemical preservatives in feed?

• A. To reduce spoilage and extend shelf life
• B. To increase protein digestibility
• C. To improve flavor
• D. To raise energy content

Answer: (A)

Preserving feed quality during storage is the primary role of chemical preservatives. They work by inhibiting the growth of spoilage microorganisms and slowing oxidative changes that would degrade nutrients, flavor, and overall feed value. By doing so, they reduce spoilage and extend shelf life, which is the direct purpose of adding preservatives to feed. The other ideas don’t fit the direct goal of preservation. Increasing protein digestibility is generally about processing or enzyme treatment, not preservation. Improving flavor or raising energy content come from taste modifiers or the feed’s nutritional makeup, not from preservatives aimed at keeping the feed intact and safe during storage.
