“In Experiment 1, glucose was decreased by intraruminal administration of 75 or 150 g of 1,3-butanediol or by 84 or 168 g of tributyrin.”
“In Experiment 2, 75 g of 1,3-butanediol or 84 g of tributyrin administered intraruminally decreased glucose , whereas 73 g of butyric acid (pH 5.6) increased glucose compared with water or 25.6 g of glycerol.”
