R. Waldo reviewed the literature on chemical preservation of forages and concluded that much of the potential production of the original crop is lost during harvest and storage. Losses incurred during the forage harvesting process include mechanical losses as well as respiration and leaching losses. These losses negatively affect both forage quality and yield. Forage species, maturity stage, baler type, and moisture concentration at baling are among the factors that affect hay losses. Changes in hay composition during aerobic storage are caused both by respiration and by nonenzymatic chemical reactions. R. J. Wilkins reviewed the literature on forage preservation and concluded that the development of effective treatments to preserve moist hay had great potential as an area for further research. The addition of compounds or organisms intended to inhibit microbial activity, barn drying to remove excess moisture and irradiation are among the methods that have been attempted for preservation of moist hay.
