Abstract

Forage stored as hay and silage provides feed for livestock during periods when pasture growth is insufficient and for use in confinement feeding systems. This chapter summarizes current knowledge of field drying and associated changes during preservation of cool-season grasses as hay and silage. Cool-season grass hay usually dries more rapidly than legume hay, and differences in drying rate also exist among cool-season grasses. Mechanical conditioning has been shown to be an effective management practice to increase drying rates of grass hay. Respiration and microbial growth, and resultant heating during storage of high moisture hay, reduce dry matter yield and digestibility and increase fiber concentration. Silage is feed produced by controlled fermentation of high-moisture forage crops. Direct-cut silage is harvested and stored without any reduction in forage moisture. Field losses are least for direct-cut silage but storage losses can be greater than for other silage types.
