Alfalfa vs Grass Hay: Protein, Calcium and Which Animals Need Each

Quick answer: Alfalfa (a legume) has much more protein (about 15–20%) and calcium than grass hay (often 6–12% protein), making it ideal for growing, milking and working animals. Grass hay is lower in protein and higher in fibre, suiting maintenance horses, adult rabbits and animals prone to weight gain. Many rations mix both.
