Fig. 4From: 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 phosphorusModels and predicted values, based on the linear and quadratic effect of Ca (P < 0.01) and the linear effect of P (P < 0.01), for (a) plasma Ca (mg/dL) and based on the interactions between Ca and P (P < 0.01), (b) for plasma P (mg/dL) at d 21 in pigs fed diets containing from 0.14% to 0.74% standardized total tract digestible (STTD) Ca and from 0.16% to 0.50% STTD of PBack to article page
