| Abstract | ||||
| The trace element boron (B) is essential for animals and humans as well as plants. It is required for bone, mineral metabolism and has a physiological role in animal nutrition. The extent and nature of possible physiological effects or potential risks of boron in animals and humans are still at primary stage and require further investigations. The aim of this study was to evaluate the effect of dietary boron supplementation as sodium tetraborate (0, 5, 10,15,20,25.30, and 35 mgB/100 g diet) on growth performance, bone ash content, and bone strength in adult female albino rats. The results indicated that, boron supplementation affected body weight gain, femur and tibia bone weight, density, mechanical properties ( moment of inertia and stress) , total lipids, and minerals ash content (calcium, inorganic phosphorous, magnesium, and copper). On the other hand, different experimental doses of boron did not have any effect on food intake, femur and tibia bone length, mineral ash content of zinc, and bending moment of tibia bone. In addition, the results revealed that, a statistical significant increase was observed in mean values of femur bending moment in the experimental rat groups fed on diets containing high doses of boron as sodium borate. These results suggest that physiologic amounts of boron may have beneficial effects upon bone minerals metabolism and, consequently, bone characteristics. | ||||
