Characteristics of changes in postnatal ontogenesis of the compact substance thickness of the stylopodian bones of coral sheep
The dynamics of changes in the absolute indicators of thickness of dorsal, palmar and plantar compact matter of stylopod bones of Karakol sheep during postnatal ontogeny were studied. The absolute dimensions of the thickness of the dorsal, palmar and plantar compact matter of the shoulder and femur,...

| description | The dynamics of changes in the absolute indicators of thickness of dorsal, palmar and plantar compact matter of stylopod bones of Karakol sheep during postnatal ontogeny were studied. The absolute dimensions of the thickness of the dorsal, palmar and plantar compact matter of the shoulder and femur, regardless of the living conditions of Karakol sheep, slightly increased in connection with the period of receiving mother's milk from the first 3 days to 3 months of postnatal ontogeny, and remained almost unchanged at the 6 and 12 month stages, the period of physiological maturity of animals, i.e. 18 months, was found to show the highest rate compared to other studied ages; In the stages of postnatal onto-genesis of black sheep after 18 months, the physiological changes in the bones observed in connection with their first postpartum period, as well as due to the expansion of the marrow space of the bones, the absolute indicators of the thickness of the dorsal, pal-mar and plantar compact substances of the shoulder and thigh bones were observed to decrease; In connection with the morphofunctional state of the micro anatomical structures of the tubular bones and the level of the weight force applied to them, the absolute parameters of the thickness of the pal mar and plantar compact matter of the shoulder and femur at the studied stages of the postnatal ontogeny of black sheep were higher than this indicator of the dorsal compact matter, and also dorsal, pal-mar, plantar compact matter is noted to be thicker in the femur than in the humerus; The absolute indicators of the thickness of the dorsal, pal-mar, plantar compact matter of the shoulder and femur bones in the studied physiological stages of postnatal development were observed to be slightly higher in Karakol breed sheep in the mountainous region compared to those in the desert region, in connection with the geographical relief and natural conditions of the regions. |
