Abstract
The purpose of this study was to identify general principles for the organization of bone structure of the pelvic limb stylopodia of Bos taurus taurus as part of the biomechanical link of phalangeal tetrapods, features of the structure of the femur, inherent in animals with high weight.
Material and methods. We conducted an osteometric study of the femurs of 40 animals with subsequent statistical processing of data and the conduct of multivariate factor analysis. After determining the parameters of descriptive statistics, without finding a normal distribution, we have calculated the confidence intervals of the relative values for each structure, and also to compare the drugs of the right and left sides, the Wilcoxon test was calculated for p<0.05. The maximum likelihood factor analysis was performed using the rotation of Equamax normalized with the determination of the factor load factor for each structure studied separately for drugs on the right and left sides.
Results. As a result, differences in the structure of contralateral bones were determined. The presence of a latent morphofunctional asymmetry of the structure of the bones of the proximal segment of the hindlimb of the bull with a clear motor differentiation of the left femur, which is not determined by the methods of descriptive statistics, is revealed.
