This study was conducted to investigate the effects of dietary boron (B) supplementation on serum calcium (Ca), inorganic phosphorus (Pi), magnesium (Mg) levels and alkaline phosphatase (ALP) activity related to bone metabolism in quails. Two hundred and eighty, Japanese quails (Coturnix coturnix Japonica) aged one-day were divided into five groups with four replicates and they were fed 0, 10, 60, 120 or 240 mg/kg B supplemented diets until 35 days of age. At the end of the study, a total of 20 blood samples were collected from each group and serum Ca, Pi, Mg levels and ALP activity were determined. Serum Ca levels decreased in all groups, Pi levels decreased in 120 and 240 mg/kg B supplemented groups and also Mg levels decreased 60, 120 or 240 mg/kg B supplemented groups. No changes were observed in serum ALP activity. In conclusion, 10 mg/kg and over doses of B supplementation to quail diet except ALP activity, decreased serum Ca, Pi and Mg levels, indicators of mineral and bone metabolism of organism. Therefore, further studies with lower levels of B in the form of boric acid supplementation may be more valuable for the field applications
