Biometric evaluation of the trunk region of Iranian Arab horse

There are more than two hundred horse breeds in the world that have different body structure, color and specific abilities depending on the geographical and weather conditions of their region. The Arabian horse, which history goes back about5 thousand years ago, has played a key role in the life history of human. Since the size of trunk region of breeds are different, biometric indices could be used to identify different breeds of horses. The present study was designed to determine the biometric indices of different trunk region were evaluated in 30 Iranian Arab horses. In this study 13 characteristics of different trunk regions were evaluated in 30 Iranian Arab horses. These horses were at least 3 years old and were selected from Kerman horse corrals. Then the mean, standard deviation, coefficient of variation and confidence interval of the characteristics were calculated. The data were compared between male and female as well as between the age groups older and younger than 8 years old by independent t-test. The results of this study showed that the gluteal height and length of lateral aspects of pelvis had the lowest and highest coefficient of variation among the measured characteristics, respectively. In this research, the characteristics were compared in different age and sex groups. This comparison showed a significant difference in the gluteal height in two different sex and age groups and length of lateral aspects of pelvis in two different age.
