Evaluation of an electronic device used as a quick screening method to detect changes in the red cell content of the blood in horses participating in endurance trail rides.

This research article presents an electronic device designed for instantaneous assessment of dehydration levels in horses during endurance trail rides, based on the connection between the red cell content and the electrical conductivity of the blood.

Overview of the Study

• The research article addresses the issue of dehydration in horses during endurance trail rides and presents an innovative solution in the form of an electronic device. This tool tackles the problem of hydration loss, a common challenge associated with physical exertions, such as endurance rides, arising due to evaporative cooling. This loss of water is caused by extensive or strenuous activity and also depends on environmental conditions like temperature and humidity.

Electrometer: The Electronic Apparatus

• The primary focus of the research is the electronic apparatus, referred to as the electrometer, which was developed to be a faster alternative to the traditional method of venous haematocrit assessment. The conventional approach requires considerable time as it involves the examination of blood samples to estimate the proportion of red blood cells in the blood, thus evaluating a horse’s hydration status.
• The electrometer operates on the basis of the direct relationship between red blood cell content and the electrical conductivity of blood. In essence, the electrometer measures the electrical conductivity of the horse’s blood, which can then be used to infer the hydration level of the animal.

Evaluation of the Electrometer

• In testing the effectiveness of the electrometer, the readings from the electronic device were compared to results from the traditional method of venous haematocrit. The researchers found a significant correlation between the two methods, with a correlation coefficient (p-value) of less than 0.001.
• A p-value of less than 0.001 indicates a highly significant correlation, strongly validating the reliability of the electrometer as a speedy yet dependable tool for evaluating a horse’s hydration status immediately after a blood sample is taken (venepuncture).
