Extract

The effect of increasing energy supply through fat supplementation (Douglas et al., 2004) in transition period on plasma leptin concentrations was not elaborated. The main objective of this study was to determine the effects of supplemental fat in transition cow diets, with differing caloric densities, on plasma leptin, glucose and NEFA concentrations.
