FEATURES OF CHANGE IN POSTNATAL ONTOGENESIS OF FINGER BONE MORPHOMETRIC INDICATORS OF JAPANESE QUAILS

The features of changes in the morphometric dimensions of the bones of the fingers of Japanese quails with and without probiotic application were studied in postnatal ontogenesis. Absolute indicators of finger bone length Japanese quails receiving probiotics have been found to increase rapidly up to 15 days of postnatal ontogenesis, while in a group without probiotic application, this process occurs at 25 days; it has been noted that the absolute index of finger bone weight increases in one measure from the first day of postnatal development to 60 days, slows down this process at 120 and 294 days, and is higher in the probiotic applied group than in the non-probiotic; the growth factor of the absolute index of finger bones has been observed to be higher in the group with probiotic administration up to 294 days of postnatal ontogenesis than in the group with no probiotic intake.
