Abstract/OtherAbstract:
The study included 249 horses belonging to three horse breeds. Konik horses, comprising the first group, are an example of breed similar to the extinct Tarpan. In our study, these horses were taken to be a primitive anatomical model of the horse body. The other groups comprised the Polish Half-bred horse and the Thoroughbred horse. The biometric characteristics of the horses were compared based on 24 indices. The aim of the paper was to find a reduced set of indices that can be used to determine group membership of the horses. To do this, we used statistical methods to find the most important indices which best discriminate breeds from each other. Chi-Squared statistics, Linear Discriminant Analysis, Logistic Regression and one-way ANOVA showed that the discrimination between groups of horses is connected with the following five indices: scapula, smaller trunk (distance between the tubercle of humerus and the coxal tuber), greater trunk (distance between the tubercle of humerus and the ischial tuberosity), metacarpus circumference and hind autopodium-smaller trunk. Thoroughbred and Half-bred horses are clearly different in exterior conformation from Konik horses. The differences between Thoroughbred and Half-bred horses are more subtle. The conformation of Thoroughbreds is jointly determined by relatively small differences in a range of features.
