Effect of Erythromycin and Gentamicin on Abomasal Emptying Rate in Suckling Calves

Abstract

IM injection of erythromycin increased abomasal emptying rate in dairy calves, whereas low-dose and high-dose gentamicin did not alter the rate of abomasal emptying as measured by acetaminophen kinetics and glucose absorption. The clinical relevance of these findings remains to be determined.
