Biochemical markers of bone metabolism in draught and warmblood horses.

This study explored the relationship between two indicators of bone health (ICTP and OC) and factors such as age, breed, and sex in healthy adult horses. The research showed a significant inverse correlation with age for both markers, different levels of ICTP and OC in Draught and Warmblood horses after adjusting for age, and a significant correlation between the two markers.

Research Aim and Methodology

• The aim of this study was to evaluate the concentrations of ICTP (cross-linked carboxyterminal telopeptide of type I collagen) and OC (osteocalcin) in the blood serum of one hundred clinically healthy adult horses, both Draught and Warmblood breeds.
• The analysis compared how these markers are influenced by the type of horse, its gender, and age.

Key Findings

• There were no significant variations observed in these markers between male and female horses.
• The analysis showed a significant inverse relationship with age for both ICTP and OC.
• After correcting for age, they found that Draught horses had lower levels of OC but higher levels of ICTP than Warmblood horses.
• A significant correlation was established between the two markers. This correlation was stronger when the type of horse was taken into account in the statistical model.

Implications of Findings

• The ratio of OC to ICTP was not influenced by the gender or the age of the horse.
• Warmblood horses had a higher OC to ICTP ratio compared to Draught horses which may indicate a higher level of bone remodelling in horses that are worked on a regular basis.
• In conclusion, the type of horse appears to have a significant effect on the levels of ICTP and OC, suggesting a physiological variation in bone remodelling between different breeds. This could have implications for understanding, monitoring, and managing the bone health of different types of horses.
