Extract

The dry matter (DM) intake of ruminants offered grass silage is normally less than that of animals offered fresh grass or hay produced from the same sward. End products of fermentation including acids and nitrogenous constituents have been implicated in this depression (Gill, Rook and Thiago, 1988). The aims of the present study were to examine the possible role of amines and juice expressed from silage in silage intake control and to determine if their effect, if any, was due to either oropharyngeal factors or post ingestive mechanisms.
