Сравнение поперечных сечений плечевой и бедренной костей, фаланги пальца и тибиотарзуса у 6-летней особи выявило, что тибиотарзус наименее подвержен резорбции. Для дальнейших исследований у 7 особей эта кость была разделена на 3 участка (Т1, Т2 и Т3), для каждого из которых проведено описание и измерение микроструктуры поперечных срезов. Выявлено, что процесс резорбции периоста начинается в 2,5 года с появления первичных остеонов. После 3,5 лет они проникают во все слои периоста, располагаясь цепочками между линий склеивания. В 4,5 года на их месте появляются вторичные остеоны, а на пересечении гаверсовых и фолькмановских каналов образуются участки резорбции. В 5,5 лет исчезает медуллярная кость из полости кости, на месте участков резорбции появляются округлые пустоты, по краям заполняемые центростремительным отложением новой костной ткани. В 6-7-летнем возрасте происходит перерождение костной ткани, когда пустоты укрупняются и сливаются в большие резорбционные полости, вплоть до полной резорбции мезоста. На дистальном участке тибиотарзуса (Т3) отмечена длительная аппозиция слоёв периоста и наиболее поздняя резорбция. С помощью морфометрии поперечных срезов середины диафиза выявлено увеличение толщины периоста и снижение плотности популяции остеонов. Определены участки тибиотарзуса, где возраст самок соответствует ростовым слоям периоста, а также выделены участки с дополнительными линиями склеивания. Сделан вывод о пригодности периостального слоя тибиотарзуса кур на дистальном и проксимальном участках в качестве регистрирующей структуры.</p></abstract><trans-abstract xml:lang="en"><p>To assess the possibility of using the bird bone tissue as a recording structure, the histomorphological parameters of the bone tissue of laying hens of the lohman brown cross from the Kirov region (9 females and 1 male) aged from 1 month to 7.5 years were investigated. The comparison of the cross-sections of the humerus and femur, the phalanx of the toe and tibiotarsus of a 6-year-old individual revealed that tibiotarsus is the least susceptible to resorption. For further research in 7 individuals, this bone was divided into 3 sections (T1, T2 and T3), for each of which the description and measurement of the microstructure of the cross sections was carried out. It was revealed that the process of resorption of the periosteum begins at 2.5 years of age with the appearance of primary osteons. At the age of 3.5 years and later they penetrate into all layers of the periosteum, locating in chains between the lines of arrested growth. At 4.5 years of age, secondary osteons appear in the place of the primary ones, and areas of resorption are formed at the intersection of the Haversian and Volkmann canals. At the age of 5.5 years the medullary bone disappears from the bone cavity, rounded cavities filled with centripetal deposition of new bone tissue at the edges appear within the resorption sites. At the age of 6-7 years, bone tissue degeneration occurs, when the small cavities enlarge and merge into large resorption cavities, up to the complete resorption of the mesost. In the distal part of tibiotarsus (T3), a prolonged apposition of the layers of the periosteum and the latest resorption were recorded. The increase of the thickness of the periosteum and a decrease in the density of the osteon population was revealed by the morphometry of cross sections of the center of diaphysis. The sites of tibiotarsus where the age of females corresponds to the lines of growth layer of the periosteum were determined. The sites with additional lines of the arrested growth were demarcated. It was concluded that the periosteal layer of the domestic fowl tibiotarsus in the distal and proximal sites are suitable as a recording structure.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Gallus gallus domesticus</kwd><kwd>кросс ломан браун</kwd><kwd>определение возраста</kwd><kwd>микроструктура кости</kwd><kwd>большеберцовая кость</kwd><kwd>периост</kwd><kwd>линии склеивания</kwd><kwd>резорбционные полости</kwd><kwd>медуллярная кость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Gallus gallus domesticus</kwd><kwd>crossbreed lohman brown</kwd><kwd>age determination</kwd><kwd>bone microstructure</kwd><kwd>tibiotarsus</kwd><kwd>periosteum (outer circumferential layer)</kwd><kwd>lines of arrested growth (LAGs)</kwd><kwd>resorption cavities</kwd><kwd>medullar bone</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке Минобрнауки России в рамках Государственного задания ФГБНУ «Всероссийский научно-исследовательский институт охотничьего хозяйства и звероводства имени профессора Б.
