What is the role of vitamins in animal nutrition?

• A. They are essential for health and can be impacted by harvesting and storage.
• B. They supply most of the energy.
• C. They are only required in growing animals.
• D. They have no impact from processing.

Answer: (A)

Vitamins are essential micronutrients needed for normal metabolism, growth, reproduction, and immune function. Because animals often can’t synthesize enough of them, vitamins must be supplied in the diet. Their levels in feed can be reduced by harvesting, processing, and storage since many vitamins are sensitive to heat, light, and oxygen. This makes vitamin supplementation or premixes important to ensure animals get enough, even after processing or storage. Vitamins do not provide energy—that comes from carbohydrates, fats, and proteins. They’re needed across life stages, though exact amounts vary with growth, lactation, or health status. Processing can impact vitamin content, so saying there’s no effect from processing isn’t accurate. The best statement therefore highlights both the essential health role of vitamins and their vulnerability to harvesting and storage.
