Numbers in parenthesis are the confidence interval. Balance A = 40 kg BW; Balance B = 70 kg BW; Balance C = 100 kg BW; LP = low phosphorus diet; MP = medium phosphorus diet; HP = high phosphorus diet; NS = not significant.
a,bWithin a row, means without a common superscript differ.
1It should be noticed that HYP represents both formation and resorption.
