Abstract | PURPOSE: MATERIALS AND METHODS: A total of 18 gravid crossbred sows (Large White × Landrace) were randomly allotted into three treatment groups: 5% HP, 10% HP, and gelatin diet. All sows were catheterized 1 day before starting treatment diet. Catheters were left in place for 5 days before being removed. Sows were recatheterized for urine collections on days 11 to 12 and days 21 to 22. Urine was collected for each entire 24-hour period, and urinary oxalate was determined by ion chromatography. RESULTS: Urinary oxalate concentrations for all three diets peaked within the first 5 days of the diet. The sows fed the 5% HP, 10% HP, and gelatin diets had an early peak in urinary oxalate concentration (mg/L) at day 2 (158% increase), day 5 (316% increase), and day 5 (830% increase), respectively. The day 21 to 22 time points in all three diets demonstrated markedly increased urinary oxalate concentrations in comparison with baseline, with some concentrations higher than the early time point peaks (day 22: 5% HP=1906% increase, P=0.12; 10% HP=640% increase, P=0.02; gelatin=501% increase, P=0.01). CONCLUSION:
