Fig. 4From: Regulation of bone phosphorus retention and bone development possibly by related hormones and local bone-derived regulators in broiler chicksEffect of dietary NPP level on Ca, Phosphorus and BGP concentrations and ALP activity in the tibia of broilers. A The tibia ash Ca and phosphorus concentrations and tibia BGP concentration and ALP activity at 14 days of age. B The tibia ash Ca and phosphorus concentrations and tibia BGP concentration and ALP activity at 28 days of age. C The tibia ash Ca and phosphorus concentrations and tibia BGP concentration and ALP activity at 42 days of age. All values are expressed as means ± SD, n = 7/8 per group. Lacking the same letters (a, b, c) means differences at P ≤ 0.05. Ca, calcium; ALP, alkaline phosphatase, BGP, bone gal protein; NPP, non-phytate phosphorusBack to article page
