Effect of dexamethasone, feeding time, and insulin infusion on leptin concentrations in stallions.

Published: 2005-10-05

Brief content of the article
The authors conducted three experiments in which the following hypotheses was tested: “daily cortisol rhythm, feeding time, and/or insulin infusion affect(s) leptin secretion in stallions”. The authors concluded that feeding time, and more specifically the insulin increase associated with a meal, but not cortisol rhythm, drives the postprandial increase in plasma leptin concentrations in horses.
