Abstract

The objective of this study was to determine the effect of ghrelin on dry matter intake and energy metabolites in ewes during the last 10 d of gestation. Ewes were randomly assigned to either a treatment (n = 6) or a control group (n = 6). One hour after feeding (08:00 and 16:00), ewes in the treated group were given ovine ghrelin (3 μg/kg, i.m.) and the control group received an equivalent volume of saline. Treatments were continued until lambing. Daily blood samples were taken starting at assignment. The principal findings were that: (1) ewes treated with ghrelin had a higher dry matter intake only on the first day of treatment; (2) treated ewes had lower serum concentrations of non-esterified fatty acids and insulin but higher serum concentrations of growth hormone; (3) serum concentrations of β-hydroxy butyrate and cortisol were not different between treated and non-treated ewes. In conclusion, treatment with ghrelin affected dry matter intake and energy metabolites of pre-partum ewes during the last 10 d of pregnancy. © 2006 Elsevier Inc. All rights reserved.
