Özet:

In this study, the age factor of Turkish Spotted horses, the effects on various body measurements were investigated by using MANOVA test from multivariate statistical methods. The horses were divided into four age groups as 1-2 years, 2-3 years, 4-5 years and 5 years of age. Body measurements examined in horses were height at withers, height at rump, body length, heart girth circumference, chest depth, chest width, tail length, cannon circumference and head length. Height at withers, (R2 = 0.68), height at rump height (R2 = 0.66) and chest depth (R2 = 0.64) were the most determined respectively differences between body size of the horses according to the age. Differences between the body measurements according to ages are found as statistically significant. Differences among horses 1-2 years with 2-3 years, 4-5 years and 5 years of age were significant (P <0.01) according to height at withers, height at rump, body length, heart girth circumference, chest depth, chest width, tail length and head length. Differences between the horses 1-2 years with 2-3 years, 4-5 yearsand 5 years of age were significant in terms of cannon circumference (P <0.01). Difference at cannon circumference between 2-3 years old horses with horses older than 5 years was significant (P <0.05). Consequently, while 4-5 years old horses had the highest chest depth, older than 5 years, in horses older than 5 years of other dimensions had been found to in the maximum value.
