Dietary acidification enhances phosphorus digestibility but decreases H+/K+-ATPase expression in rainbow trout.
Oxynticopeptic cells of fish stomach are thought to secrete less acid than the specialized parietal cells of mammalian stomach. Gastric acidity, however, has not been directly compared between fish and mammals. We therefore fed rainbow trout and rats the same meal, and found that the lowest postprandial pH of trout stomach was 2.7, which was only transiently sustained for 1 h, whereas that of r...
متن کاملDietary phosphorus-responsive genes in the intestine, pyloric ceca, and kidney of rainbow trout.
Identification of phosphorus (P)-responsive genes is important in diagnosing the adequacy of dietary P intake well before clinical symptoms arise. The mRNA abundance of selected genes was determined in the intestine, pyloric ceca, and kidney of rainbow trout fed low-P (LP) or sufficient-P (SP) diet for 2, 5, and 20 days. The LP-to-SP ratio (LP/SP) of mRNA abundance was used to evaluate the diff...

متن کاملGenetic responses to dietary phosphorus deprivation: lessons learned from the rainbow trout.
PHOSPHORUS (P) is a critical nutrient necessary for several key physiological processes in vertebrates, and P is also a structural component of several biological molecules. Thus an intimate knowledge of the regulation of body P homeostasis is important. Nutritional P deficiency occurs primarily in premature infants (7), and therefore, identifying genes involved in P homeostasis and understandi...
متن کاملConcentration of dietary calcium supplied by calcium carbonate does not affect the apparent total tract digestibility of calcium, but decreases digestibility of phosphorus by growing pigs.
A regional experiment was conducted to test the hypothesis that the concentration of dietary Ca does not affect the digestibility of Ca or P in diets fed to growing pigs. Six diets based on corn, potato protein isolate, cornstarch, and soybean oil were formulated. All diets also contained monosodium phosphate, crystalline AA, salt, and a vitamin-micromineral premix. The only difference among th...
