Milk by-products in animal feeds are best described as which combination?

• A. They are highly palatable and serve as protein supplements.
• B. They are primarily used as mineral supplements.
• C. They provide little palatability.
• D. They are used only as energy sources.

Answer: (A)

Milk by-products bring two key advantages to livestock feeds: they are highly palatable and they provide high-quality protein. The dairy-derived ingredients like skim milk and whey are naturally appealing to animals, improving intake, while their proteins (such as casein and whey proteins) deliver essential amino acids in a readily digestible form, making them effective protein supplements to complement more plant-based feeds. Although they do contain minerals and lactose for energy, their primary value in most diets is protein, not minerals or sole energy provision.
