Variations in plasma concentrations of GH (A) and IGF-1 (B). These variations were over a 24 h period at two different times of year (end of winter and end of spring in WF, R and V groups, means ± S.E.M, one sample each hour for GH, each 2 hours for IGF-1). The V group was fed in winter like the WF group and in spring like the R group.
