Background: Boron (B), a novel micronutrient is known to influence utilization of macrominerals. Present study was conducted in layer birds to study the effect of B supplementation to inadequate calcium (Ca) diet on mineral content in serum, tissue and antioxidant status.Methods: A total of 80 commrcial White Leghorn layers, 25 weeks old with a uniform body weight were randomly assigned to one of the 4 groups of 20 hens in each dietary group viz., Normal calcium (NC), inadequate/low calcium (LC), Normal calcium with 40 ppm B (NCB) and inadequate/low calcium with 40 ppm B (LCB). Dietary level of calcium was maintained at 100 and 90% of the requirement and sodium borate was used as B source. At the end of feeding trial, blood and tissue samples were collected for estimating mineral and biochemical parameters.Result: Boron supplementation did not significantly alter the serum mineral content, serum alkaline phosphatase and total antioxidant activity but significantly (P less than 0.025) increased the superoxide dismutase activity in layers fed inadequate Ca diet. Boron supplementation to both diets significantly (P less than 0.03) increased phosphorus (P) content in bone and muscle, and magnesium (Mg) content in muscle (P less than 0.019). Boron supplementation to Ca inadequate diet significantly (P less than 0.006) enhanced the P and Mg content in liver. Content of B was significantly (P less than 0.01) higher in serum, bone and liver of hens supplemented 40 ppm of B. Implication of this study is amelioration of abiotic stress due to inadequate Ca intake with B supplementation. It is concluded that 40 ppm B supplementation positively influenced the Ca, P and Mg utilization and serum SOD activity.
