The effect of insulin-induced hypoglycaemia on the motility of the reticulum, rumen and abomasum of sheep was investigated using small lightly inflated balloons connected to transducers and a multichannel recorder. The principle response recorded was an inhibition of reticulo-ruminal and abomasal motility, occurring in 'resting' cycles only, and not during eating or rumination. The only hypermotility recorded was that shown by the abomasum just before the onset of inhibition. Ruminating cycles were recorded as frequently during hypoglycaemia as in control periods, and showed no abnormality. The inhibition was reversed by intravenous glucose or adrenaline and by feeding or ruminating.
