Some haematological and biochemical parameters in race horses in Hong Kong.

This article studied the blood and biochemical values of racing horses in Hong Kong to understand the effects of salt intake on these parameters.

Objective and Methodology

The research aimed to understand how giving salts to race horses impacts their hematological (blood) and biochemical values. Hematological values are variables that help evaluate the condition of the blood, like the count of red or white blood cells and hemoglobin levels. Biochemical values include parameters like liver function, kidney function, and glucose levels.

Two groups of racing horses trained on the same track in Hong Kong were chosen for the study:

• Group one was composed of 217 horses from various training groups, providing 435 blood samples.
• Group two had 66 horses from one training group. These horses were given salts by a stomach tube eight hours before their blood samples were taken, providing 309 samples.

Subgroups and Evaluation

Both groups were further divided to study the effects of the salts on the horses’ hematological and biochemical values. The division aimed to provide more nuanced data, specific to the type of training and care the horses received.

The researchers cross-checked their findings by comparing them with similar studies conducted by other authors to add more credibility to their outcome.

Key Findings

The key finding from the research was that the horses which were given salts showed lower hematological values compared to the group that was not given salts.

Possible Explanation

The research considered water retention due to the given salts as a possible explanation for the adaption in hematological values. When the body consumes salt, it retains more water to maintain the balance of electrolytes in your body. This water retention could potentially affect the variables considered in determining hematological values, leading to the noted lower values. The results discussed are relevant for racehorse caregivers and veterinarians because they show how diet and specific supplements (like salt) can impact the health and performance of racehorses.
