"Calves are not usually competitive at the feedbunk, so, in a limit-fed situation 22 to 26 inches of bunk space per head are required for grain or supplement diets," says Bob Larson, extension veterinarian at the University of Missouri. "When feeding hay or silage that is available at all times, 12 to 18 inches per head is required."

To minimize wasted forage when providing hay to growing calves, a system of hay rings or hay racks should be used. For bale rings, allow 4 to 6 inches of space per head if hay is always available and 18 to 24 inches per head for limited feeding. Although hay rings usually have a maximum of 18 spaces, usage is at about two-thirds capacity based on Dr. Larson’s personal observation.
