An apparatus for collecting blood samples by radiotelemetry from horses during exercise.
Abstract: An apparatus was designed to collect four consecutive blood samples from exercising horses. The collection of each sample was controlled by valves activated by radiotelemetry signals transmitted by an observer. Using the device, venous blood samples were collected from ten thoroughbred racehorses before, during and after a 400 m training gallop. Blood glucose increased markedly post-exercise. Both phosphorus and potassium concentrations increased during exercise, decreased post-exercise and recovered to pre-exercise levels within 120 minutes. The system was modified to collect anaerobic samples of arterial and venous blood, and the efficiency of the modified system was investigated in a standing conscious horse. Blood gas values of samples collected by means of the apparatus were compared with those collected manually and simultaneously, directly from the neck of the intravascular catheter. For eight pairs of arterial and venous samples, the coefficients "r" were 0.998 and 0.997 for PO2 and PCO2 respectively. It was concluded that the system worked efficiently and that the anaerobic sealing of the modified version was adequate.

This study presents a newly designed apparatus to collect blood samples from horses during exercise using radiotelemetry, which demonstrated good efficiency and adequacy.
Introduction
The research paper introduces a novel device that’s specifically designed to collect four consecutive blood samples from horses whilst they are doing exercise. The blood sample collection is operated by valves, which are triggered by radiotelemetry signals transmitted by an observer. The main purpose of this research was to discover a non-invasive and efficient method for collecting blood samples from horses during physical activities like exercise.
Methodology and Test
- Horses Selection: The experiment was conducted on ten Thoroughbred racehorses that were made to perform a 400m training gallop.
- Sample Collection: The blood samples were collected before, during and after the exercise to analyze the changes at different time points.
- Analysis: The blood samples were then analyzed to check alterations in blood glucose, phosphorus, and potassium levels.
Findings
- The post-exercise samples showed a significant increase in the blood glucose level.
- Phosphorus and potassium concentrations were elevated during the exercise, decreased post-exercise, and returned to their original levels within 120 minutes.
Further Adjustments and Analysis
- Following these results, the system was modified to add capability for collection of anaerobic arterial and venous blood samples, and tested again on a standing, conscious horse.
- The blood gas values from the samples gathered through this device were compared with samples collected manually and directly from the neck of the intravascular catheter.
- For eight pairs of arterial and venous blood samples, the correlation coefficients for oxygen partial pressure (PO2) and carbon dioxide partial pressure (PCO2) were 0.998 and 0.997, respectively. This high correlation demonstrated the device’s effectiveness and accuracy in collecting blood samples compared to manual collections.
Conclusion
It is concluded from the areas of study that this blood collection system utilizing radiotelemetry signals is very efficient and accurate. Moreover, the anaerobic sealing modifications proved to be equally adequate. These findings, therefore, advocate for the usage of this system in veterinary medicine, especially in regards to horses participating in strenuous physical activities. The collection of blood samples from horses during exercise with an improved level of accuracy will drastically improve the level of care that these animals receive during their training, and during their overall healthcare.
