J. Hermann et al., EFFECTS OF DIETARY CHROMIUM, COPPER AND ZINC ON FEMUR FRACTURE FORCE AND FEMUR CALCIUM-CONCENTRATION IN MALE JAPANESE-QUAIL, Nutrition research, 17(10), 1997, pp. 1529-1540
The effects of dietary chromium, copper and zinc on femur fracture for
ce and femur calcium concentration were evaluated in male Japanese qua
il, Coturnix coturnix japonica, using a three-factor response surface
design. Quail were randomly assigned to one of fifteen experimental di
ets containing variable concentrations of dietary chromium (71 to 1124
ng/g diet), copper (1.6 to 8.3 mu g/g diet), and zinc (11 to 51 mu g/
g diet). After six weeks femurs were removed, weighed and frozen for f
uture analysis of femur fracture force and femur calcium concentration
. Femur fracture force was significantly influenced by the interaction
between dietary zinc and copper. In addition, bone calcium concentrat
ion was significantly affected by the quadratic effects of dietary zin
c and copper. (C) 1997 Elsevier Science Inc.
