Biochemical markers of bone metabolism in draught andwarmblood horses

Summary Concentrations of the cross-linked carboxyterminal telopeptide of type I collagen (ICTP) and osteocalcin (OC) have been determined in the serum of one hundred clinically healthy adult Draught or Warmblood horses. The correlation between these two markers has been evaluated and the influence of gender, age and type of horse described. No significant variations were observed between animals of different sex, but a significant inverse correlation ( P −1 ] than in Warmblood horses (adjusted LSM=8.596μg.L −1 ), whereas levels of ICTP were higher in Draughts (adjusted LSM=8.035pg.L −1 ) than in Warmbloods (adjusted LSM=6.643μg.L −1 ). A significant correlation ( P
