What are the benefits of using dried skim milk in animal feeds?

• A. It is used only as a flavor enhancer
• B. It is used for milk replacers and is a source of protein
• C. It provides all essential minerals
• D. It is used as a primary carbohydrate source

Answer: (B)

Dried skim milk is valued in feeds for its high-quality protein and digestibility, making it especially useful in milk replacers for young animals. The proteins in skim milk (casein and whey) provide a balanced and easily available amino acid profile that supports rapid growth and tissue development when natural dam’s milk isn’t available. While lactose in the product does contribute some energy, the primary role in milk replacer formulations is supplying protein, not acting as the main carbohydrate source. It also isn’t relied on as a comprehensive mineral source, since minerals are added separately to ensure all nutritional requirements are met. Palatability can be a bonus, but the key nutritional reason for including dried skim milk is to provide a dependable protein supply for growing young stock.
