During a 3-year period, 12 large hay packages (six alfalfa, six prairie hay) were made using either Haybuster or Hesston process and stored from 8 to 29 months. Stacks were core sampled at periodic intervals for physical (moisture, density) and quality parameters (crude protein, neutral-detergent fiber, Crampton and Maynard cellulose, acid-detergent fiber, acid-detergent lignin, ash and in vitro dry matter digestibility. The hay package storage areas were located in north-central South Dakota.
