Influence of the concentration of dietary digestible calcium on growth performance, bone mineralization, plasma calcium, and abundance of genes involved in intestinal absorption of calcium in pigs from 11 to 22 kg fed diets with different concentrations of digestible phosphorus

Table 7 Least squares means (log₂-backtransformed) for mRNA abundance in the duodenum of pigs fed diets containing different concentrations of standardized total tract digestible (STTD) Ca and STTD P for 21 d^a

^aData are least squares means of 6, 7, or 8 observations
^bStandard error of the within treatment least squares means = 0.10
^cStandard error of the within treatment least squares means = 0.09
^dResults indicated that abundance of ATP2B1 could not be predicted using STTD Ca or STTD P
^eStandard error of the within treatment least squares means = 0.04
^fStandard error of the within treatment least squares means = 0.04
^gStandard error of the within treatment least squares means = 0.03
^hResults indicated that abundance of CLDN1 could not be predicted using STTD Ca or STTD P
ⁱStandard error of the within treatment least squares means = 0.10
