The responses of plasma growth hormone (GH) and insulin concentrations to intraruminal injection of n-butyrate and acetate were examined in Holstein cows. n-Butyrate or acetate was injected into the rumen via a rumen cannula at the doses of 2.5,10 or 20mmol/kg body weight (BW). Saline was injected as control. Plasma concentrations of n-butyric acid, acetic acid, GH and insulin were measured at 20min intervals during the period of -20min to 180min after the intraruminal injections. The plasma n-butyric acid concentrations were elevated
