The effect of 48‐hour fasting on taurine status in healthy adult dogs. Issue 3 (6th August 2015) - Gray, K.
Summary: Low circulating taurine concentrations may be a risk factor for dilated cardiomyopathy (DCM) in dogs. Circulating taurine is typically measured in the clinic 4–5 h after feeding, largely because the impact of later sampling is not known. The objective of this study was to measure taurine in the blood during a 48‐h fast in 12 healthy adult Labrador Retrievers to refine sampling methodology for determination of taurine status. Plasma and whole blood (WB) taurine concentrations did not fall to levels indicative of clinical deficiency throughout fasting; WB was the more reliable indicator of taurine status. This study shows that blood samples can be taken for assessment of taurine status any time up to 48 h after ingestion of a meal in healthy adult dogs.
