Gamma amino butyric acid (GABA) is a food intake depressant (Morley, 1980) and is quantitatively a significant nitrogenous constituent in silage (Oshima and McDonald, 1978). When maize silage extracts were infused into the rumen of sheep, it was shown that short-term feed intake could be depressed but this effect was attributed to high rumen osmolality (Phillip, Buchanan-Smith and Grovum, 1981) The purpose of the present experiments was to determine whether GABA and low dry matter lucerne silage extracts could depress food intake in sheep.
