Glucose tolerance in the horse, pony and donkey

Abstract

Abstract Glucose tolerance tests were conducted on seven donkeys, seven horses and seven ponies. The average initial plasma glucose value for all equines was 86.8 mg/dl. The values increased approximately two-fold by 2 hours after oral glucose administration. Plasma glucose values for horses and ponies returned to near initial values within 6 hours (87 and 82 mg/dl, respectively), but the donkeys remained higher (114 mg/dl) (P
