Butyrate Metabolism in the Lactating Cow S-
The possibility that butyrate may be glucogenic in ruminants has been suggested by several experimental studies. Intravenous injection of butyrate in sheep was followed by increased concentrations of blood sugar (1) and, in lambs, it was found that butyrate was more effective than propionate for alleviating insulin-induced hypoglycemia (2) ; acetate injection did not have a similar effect in ei...
متن کاملDynamic model of the lactating dairy cow metabolism.
The whole-animal model described in this paper is intended to be a research model with an intermediary structure between sophisticated and simple cow models. The mechanistic model structure integrates the main metabolic pathways of the lactating dairy cow. Milk yield and related feed intake for varying production potentials were considered to be the driving forces and were empirically defined. ...

متن کاملAn integrative model of amino acid metabolism in the liver of the lactating dairy cow.
The objective of this work was to construct a dynamic model of hepatic amino acid metabolism in the lactating dairy cow that could be parameterized using net flow data from in vivo experiments. The model considers 22 amino acids, ammonia, urea, and 13 energetic metabolites, and was parameterized using a steady-state balance model and two in vivo, net flow experiments conducted with mid-lactatio...
متن کاملEffects of starvation on intermediary metabolism in the lactating cow. A comparison with metabolic changes occurring during bovine ketosis.
1. The purpose of this study was to determine the nature of the metabolic changes associated with carbohydrate and fat metabolism that occurred in the blood and liver of lactating dairy cows during starvation for 6 days. 2. During starvation, the blood concentrations of the free fatty acids and ketone bodies increased, whereas that of citrate decreased. After an initial increase, the blood conc...
