title: Sex does not influence serum osteocalcin levels in standardbred horses of different ages.
abstract: The influence of sex on serum osteocalcin levels was studied in 99 Standardbred horses, 52 males and 47 females. The age varied between the day of birth and five years old. A significant inverse correlation (r = -0.87, p < 0.01) was observed between serum osteocalcin level and the age of the animal. Sex did not influence serum osteocalcin level (p > 0.05). When the subjects were divided into five age groups of six months or less, 6 to 18, 18 to 24, 24 to 36 and between 36 and 60 months, no significant influence of sex was noted. A predictive model for serum osteocalcin levels (y = 52.19 - 0.026 age in days, r2 = 0.76) for Standardbred horses aged between the day of birth and five years is described.
