Insulin tolerance in laminitic ponies

Sensitivity to insulin was assessed in ponies episodically affected with chronic laminitis by measurement of blood glu-cose and arterial blood pressure during insulin tolerance tests. In terms of blood glucose values, laminitic ponies were signifi-cantly less sensitive to insulin than controls. Conversely, a post-insulin decline in diastolic, sys-tolic and mean blood pressure values was significantly greater in laminitic ponies than in controls
