The dynamics of changes in the relative indicators of natural moisture, ash, and total organic matter in the humerus of egg-laying chickens during postnatal ontogeny were studied. The relative amount of natural moisture content of the humerus is slightly higher on the first day of postnatal ontogenesis and gradually decreases up to 570 days, the ash content increases rapidly from the first day to 120 days of postnatal ontogenesis, continues this state without noticeable changes from 168 days to 570 days, the relative amount of total organic matter It was found that the index is higher in one-day-old chicks, it decreases until 168 days of postnatal ontogeny, and does not change significantly from 280 to 570 days.
