In this trial, alfalfa hay cubes self fed to white face and Hampshire ewe lambs resulted in small but statistically significant increases in weight gains, along with increased feed consumption but with less waste feed than when comparable ewes were fed baled alfalfa hay daily. Suffolk ewe lambs gained equally well on either cubes or baled hay.

Chemical analyses were conducted at the University of California Agricultural Extension Service laboratory at Davis. Gerald A. Darling, student shepherd, and other Chico State College students assisted in this trial.
