Table 8 Least squares means (log2-backtransformed) for mRNA abundance in the ileum of pigs fed diets containing different concentrations of standardized total tract digestible (STTD) Ca and STTD P for 21 da

From: 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
