Abstract: The objective of the present experiment was to investigate whether phytate feeding would counteract the inhibitory effect of calcium on fat digestion in rats. Rats were fed semipurified diets either low in calcium or high in calcium with various levels of added sodium phytate. Body weight and food intake were not influenced when phytate was added to the high-calcium diet. Phytate significantly raised fat digestibility and diminished group mean fecal bile acid excretion when compared to the high-calcium, phytate-free diet. The apparent digestibilities of dry matter, crude protein and ash were not affected by phytate. It is suggested that phytate feeding counteracts the inhibitory effect of calcium on fat digestion through complexing calcium in the small intestinal digesta, leading to less calcium phosphate sediment so that less bile acids are bound to the sediment and more bile acids were available for the process of fat digestion.
