Groups of animals were formed at six months based on the physiological and selection index we invented. We studied postnatal development in heifers of the high-enzyme (experimental group) and low-enzyme (control group) constitution type. Thus, due to the main diameters of body parts, which characterize the exterior in postnatal ontogenesis, animals of the high-enzyme type (experimental group) prevailed over their analogues of the low-enzyme type (control group). According to indices of the body structure in postnatal ontogeny, the development of some relative to others is evaluated. In our studies, significant superiority in the experimental group over the control analogues wasn't noted in terms of these indicators. Consonant to the leading indicators characterizing oxidation-reduction processes in the body, animals of the high-enzyme type (experimental group) significantly outnumbered their analogues of the low-enzyme type (control group). Therefore, this indicates that the level of metabolic processes in the experimental group was much more intense compared to the control group. Thus, animals of the high-enzyme type (experimental group) significantly outnumbered their analogues of the low-enzyme type (control group).
