Animals - 19 healthy Beagles. Procedure - After emptying the urinary bladder by catheterization, dogs were fed a canned canine maintenance diet. Approximately 8 hours later, urine, plasma, and serum samples were obtained for determination of urinary carnitine fractional excretion and urine carnitine-to-creatinine concentration ratio. Results were compared with 24-hour urinary carnitine excretion rate. Results - Fractional excretion of carnitine and urine carnitine-to-creatinine ratios correlated poorly with 24-hour urinary carnitine excretion. Conclusion - Determination of 24-hour urinary carnitine excretion is recommended to measure urine carnitine concentrations in dogs.1185-1188engbiological markercarnitineanimalanimal foodbloodcomparative studydogfemalemaleorchiectomyovariectomypostprandial statereference valuereproducibilityurineAnimal Nutrition PhysiologyAnimalsBiological MarkersCarnitineDogsFemaleMaleOrchiectomyOvariectomyPostprandial PeriodReference ValuesReproducibility of ResultsArtigoAcesso restrito2-s2.0-0030208399
