PSXVI-14 Hindgut Disappearance of Phosphorus in Corn-Soybean Meal-Based Diets with or without Inorganic Phosphorus Sources in Twenty-Four-kg Pigs

Abstract The objective was to investigate the hindgut disappearance of phosphorus (P) in corn-soybean meal-based diets with or without inorganic P sources pigs. Hindgut hypothesized be greater a diet than P. Barrows (n = 5; initial body weight 23.5 ± 3.1 kg and final 33.7 5.5 kg) fitted T-cannula distal ileum were individually housed pens equipped feeder nipple drinker. Two formulated inclusion No phytase supplemented diets. All contained 0.5% chromic oxide as an indigestible index. pigs allotted 2-period crossover design 2 A fed other 3 each period. An additional period conducted after periods obtain replicates for treatment. Each consisted 7-d adaptation period, 2-d fecal collection ileal Apparent (54.7 vs. 35.0%) total tract (53.7 34.3%) digestibility values P-containing (P < 0.01) those However, apparent comparable > 0.90) irrespective diets, thus, significant amount not observed both In conclusion, negligible 23-kg growing regardless sources.
