Impacts of dietary supplemental phytase and inulin on bone mechanical and chemical properties of young pigs.
Enhancing peak bone mass and integrity early in life may reduce or delay osteoporosis. We explored benefits of supplementing phytase and inulin in a P-adequate, corn-soybean meal basal diet (BD) on bone development in young pigs. The present study was conducted with 35 weanling pigs (8.5 ± 1.6 kg) to compare the effects of supplementing a bacterial phytase at 3,500 units/kg (OptiPhos, JBS United, Sheridan, IN) and inulin at 4% (Synergy-1, Orafti, Tienen, Belgium) on bone mechanical and chemical properties. Pigs were fed BD, BD + phytase, BD + inulin, or BD + phytase + inulin for 5 wk. Five pigs were euthanized from each diet group to collect the femur. Supplemental inulin exerted marginal (P = 0.06 to 0.08) effects on femur height, modulus elasticity, and cancellous bone ash concentration. Cortical bone concentrations (ash basis) of Mg, Na, Sr, and Zn were altered (P
