Fig. 5From: 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 the total Phosphorus accumulation in the tibia ash of broilers. A the total phosphorus accumulation in tibia ash at 14 d of age. B the total phosphorus accumulation in tibia ash at 28 days of age. C the total phosphorus accumulation in tibia ash at 42 days of age. All values are expressed as means ± SD, n = 7/8 per group.
