Effect of intravenous infusion of glucose and/or fructose on the composition of blood plasma and the clinical response of the calf.

Intravenous infusions of glucose (0.4 g/kg) or glucose (0.4 g/kg) + fructose (usually 1 g/kg) to calves were followed by various clinical reactions from absence of reaction up to death of a few calves. Fructosemia. After fructose + glucose infusion, the blood fructose concentration reached a level inferior to the highest value observed after only glucose infusion, except in the calves dead after the perfusion and in the newly-born calves (the initial fructose concentration was not nil). Glycaemia. In any case, fructose associated with glucose, did not eliminate the rebound of hypoglycaemia following usually a perfusion of glucose. In calves where the death occurred, the hypoglycaemia was specially marked.
