Concentrates are used as which in diets?

• A. Primary energy and protein source
• B. Primary energy source
• C. Primary vitamin source
• D. Primary water source

Answer: (A)

Concentrates are feeds that are high in digestible energy and often provide substantial protein, with low fiber. In livestock diets they’re used to boost the animal’s energy and protein intake, especially when rapid growth, high milk production, or heavy work is needed, and to balance diets that are mainly forage. Because of their dense energy and protein content, concentrates serve as the primary energy and protein source in many rations. They’re not intended as major vitamin sources or water sources, though they may contain vitamins or minerals alongside the main role of delivering energy and protein.
