The objective was to determine the effect of ghrelin on feed intake (FI) and energy metabolites in lambs. Sixteen lambs were randomly assigned to either a treatment (n=8) or a control group (n=8). Lambs in the treated group received ghrelin intramuscularly (5 μg/kg of body weight [BW]) and the control group received an equivalent volume of saline 3h after(More)
