Postprandial changes in plasma urea and creatinine concentrations in dogs
American Journal of Veterinary Research
|November 1, 1981
Summary
Diet significantly impacts canine kidney function markers. Different dog food types, including cooked, raw, and soft-moist meals, altered plasma urea and creatinine levels, complicating renal function assessments.
Area of Science:
- Veterinary Medicine
- Animal Nutrition
- Biochemistry
Background:
- Plasma urea and creatinine are key indicators of renal function in dogs.
- Dietary intake can influence these biochemical markers.
- Understanding these influences is crucial for accurate veterinary diagnostics.
Purpose of the Study:
- To investigate the impact of different canine diets on plasma urea and creatinine concentrations.
- To determine if dietary variations affect the interpretation of renal function tests.
Main Methods:
- A crossover study design was employed with 6 dogs.
- Dogs were fed three distinct meals: cooked meat, raw meat, and a soft-moist preparation.
- Plasma urea and creatinine levels were measured after each meal.
Main Results:
- All tested diets caused changes in plasma urea and creatinine.
- Plasma urea increased following all meal types.
- Plasma creatinine concentrations varied, increasing after cooked meat but decreasing after raw or soft-moist diets.
Conclusions:
- Dietary composition significantly affects plasma urea and creatinine levels in dogs.
- The variable impact of diet, particularly on creatinine, complicates its use as a sole indicator of renal function.
- Veterinarians should consider recent diet when interpreting these blood parameters for canine kidney health.
