Bombesin-like peptides stimulate growth hormone secretion mediated by the gastrin-releasing peptide receptor in cattle

► Effect of bombesin-like peptides on growth hormone secretion was tested in cattle. ► Growth hormone level was increased by gastrin-releasing peptide (GRP). ► Growth hormone level was unaffected by neuromedin B. ► The GRP-induced growth hormone secretion was mediated by GRP receptors. ► Ghrelin/GHS-R system was not involved in GRP-induced growth hormone secretion.
