What characteristics do hays possess relative to other feeds?
Hays are bulky, high in fiber, modest in energy content, higher in calcium than phosphorus, high in potassium, high in vitamins A, E and K. If hay is sun-cured it is higher in vitamin D than grains. Protein content depends on the type of hay and when it is harvested. Alfalfa hay is typically high in protein and calcium. Timothy and brome hays are usually lower in protein and lower in calcium content.
