Anti-ketogenic effect of glucose in the lactating cow deprived of food.
1. The aim of this study was to determine the effect of a constant infusion of glucose on the ketosis that is observed when dairy cows are deprived of food in early lactation. 2. Cows in early lactation were first deprived of food for 4 days (96h) to induce a 'fasting ketosis'. Glucose was then infused intravenously at a constant rate of 0.75 g/min for 48h while deprivation of food was maintain...
متن کاملHepatic uptake of gluconeogenic substrates in late-pregnant and mid-lactating rats.
Lactate uptake by liver is markedly increased in late-pregnant and mid-lactating rats without concomitant changes in its availability. Glycerol contribution to the liver 3-C unit uptake is only significant at term gestation (50% of lactate uptake) but almost negligible at mid-lactation (10% of lactate uptake). Pyruvate is only taken up by the liver of 15-day lactating rats. As a general trend, ...
متن کاملButyrate 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 کاملInterrelationships of Heat Stress and Reproduction in Lactating Dairy Cows
Efficient reproductive performance of lactating dairy cattle in tropical/subtropical and arid environments throughout the world is impacted by a multiplicity of factors such as: the physical environment, socialeconomic status of producers, available nutrients, adaptability and genetic composition of cattle, intensive or extensive management systems, and available reproductive technology. Season...
