The Effects of Different Dietary Oil Sources on Broiler Chicken Bone Mineralization

This study was designed to determine the effects of dietary hazelnut oil (HO) and sunflower oil (SO) on the mineral composition of chicken femur and tibia bones. A 40-day trial was initiated with 600 1-day-old Ross 308 chickens. Initially, the chickens were randomly divided into four main groups of 150 each according to the proportion of SO and HO supplementation in their diets: control SO (25 g/kg SO), LHO (25 g/kg HO), HHO (50 g/kg HO), and MO (50 g/kg blend of 25 g/kg SO + 25 g/kg HO). Each group was further divided into six subgroups of 25 chickens. At the end of the trial, four chickens from each of the six subgroups were randomly selected and slaughtered. Their right tibia and right femur bones were isolated and analyzed for macro (Ca, P, Mg) and trace (Fe, Cu, Mn, Zn, Cr, Co, and Se) minerals in addition to ether extract and ash. The results suggest that the diets’ fat concentration and fatty acid composition significantly affected the Ca, P, Mg, Fe, Cu, Cr, and Se composition of tibia bones ( p
