Serum glucose levels were measured by GlucoDr Blood Glucose Meter. Serum GH concentrations were measured by GH RIA. Serum IGF-1 and corticosterone levels were measured by ELISA. Values are expressed as mean±SEM., n=5 animals/group. *, indicates values differ from respective fed controls; *, p<0.05.
