Always use the concept of a pound of forage is a pound of forage regardless of its form. A pound of baled forage is the same as a pound of pellets or a pound of cubes. We recommend that animals be fed by weight and not by volume; therefore if you are currently feeding 10lbs of alfalfa from a bale and changing to alfalfa pellets or cubes then you should feed 10lbs of alfalfa pellets or cubes.
