Mechanically treating hay for moisture removal

Authors: Kurtz, P. J. And W. K. Bilanski
Description: The loss of feed value, in weather-damaged hay, can vary from 25 to 40 per cent (9), and is a major concern to forage producers. It is desirable that hay be stored as quickly as possible after cutting to minimize losses and preserve quality. Numerous research programs performed over the past years have revealed that mechanical treatment of the hay increased the drying rate over the untreated material. Geographic location also tended to have a bearing for some mechanical treatments on their hay drying rates. A review of the published literature revealed that crushing (2, 3, 5, 6, 7, 8, 10) and crimping (6, 7) of the hay increased the drying rate over untreated hay, with the former treatment removing moisture quicker than the latter (1). Swathed material dried faster than windrowed material of the same treatment (5). Geographic location appeared to have an effect on the flail mower treatment as Boyd (1) and Hall (4) found hay with this treatment dried quicker than crushed hay and Halyk (5) and Kurtz (8) found the opposite to occur.
