ABSTRACT Calcium distribution was studied in the small intestine of piglets fed skim milk powder (SMP) or defatted soybean flour (DSF) to investigate the relationship between calcium availability and its forms. Ionized calcium in duodenal and ileal digesta was measured with a selective calcium electrode that was not affected by changes in pH or sodium, potassium and magnesium concentrations, which simulated the liquid phases of digesta. Eight piglets were fed DSF-based diet or SMP-based diet for 30 d, and duodenal and ileal digesta were collected. Soluble calcium concentrations in the ileum were higher in the SMP-fed group than in the DSF-fed group. The proportion of soluble calcium in ...
