Popis:	The objectives of this study were to characterise reproductive and metabolic endocrinology parameters in Romney rams from lines selected since 1986, for high or low circulating IGF-1 concentrations. Seasonal changes were recorded in the patterns of IGF-1, insulin and the response of serum testosterone to hCG administration. Serum testosterone concentrations, adjusted for covariance with IGF-1 concentrations, were higher in both strains (P
