Investigated were morphological and densitometric parameters of the tihiotarsal bones in White Kołuda Geese over postatal period as influenced by sex, age and bone area using dual-energy Xray absorptiometry and peripheral quantitative computed tomography. The study was performed on 100 bones of geese obtained from both sexes on 1, 14, 28, 42 and 56 day of life. Body weight,bone weight, bone mineral density (BMD), bone mineral content (BMC), volumetric bone mineral density (vBMD), total bone mineral content (tBMC), cortical bone mineral density (CTR_DEN),cortical bone mineral content (CRT_CNT), trabecular bone mineral density (TRAB_DEN) and trabecular bone mineral content (TRAB_CNT) of tihiotarsal bone were determined.vBMD in the proximal metaphyses generally increased with age in both sexes and in females was higher than in males (especially in mid-diaphysis). Similar trends were observed for tBMC in middiaphysis of bones. The tBMC in proximal metaphyses reached maximum in females as early as on day 28, whereas in males 2 weeks later (on day 42). A significant decrease in TRAB_DEN and TRAB_CNT was also observed in males in both sections of the bone on day 42 and 56, whereas TRAB_DEN in the mid-diaphysis attenuated between day 28 and 42. Most deformities of tibial bones in males were observed in week 6 (42 day). In females, tibiotarsal deformations and fractures were found in week 6 and 8 of age, which was slightly later than the critical developmental stage in males.
