Values represent ± standard deviation. Values with different letters differed significantly using Duncan’s multiple range test (p < 0.05). OVX = ovariectomized; * Sham Normal, Positive Control = normal diet (TD.97191); ** Negative Control = OVX diet (low calcium diet, TD.95027); GD collagen groups = GD collagen proportion deduced from casein content in OVX diet, administration by oral gavage, GDC2, GD collagen 2 g/Kg, GDC3, GD collagen 3 g/Kg; 1 FER: Food efficient ratio = body weight gain (g/week)/feed intake (g/week).
