- Abstract
For the first time computed tomography has been used to analyse tibiotarsal bones volumetric mineral density (vBMD) and mineral content (BMC) in quails during their post-hatching development. The analysis was performed including eighty male and female quails aged 2, 4, 6 and 8 weeks, respectively. Statistical calculations were performed using two-way ANOVA. It was found that vBMD generally in the middle of the diaphyses in the tibiotarsal bones in quails was two-fold higher vs. the metaphyses. Decrease of vBMD and BMC in the metaphyses of the tibiotarsal bones in males occurred between the 4 wk and 6 wk of the post-hatching development; the lowest values of vBMD (217 mg/ccm) and BMC (3.68 mg/mm) were observed in 6 wk males. In turn, in females, the decrease of vBMD in the metaphyses occurred in the 4th and 8th wk. Pearson's correlation coefficient between the metaphyseal vBMD and body weight in males was negative and amounted to r = - 0.71 in the 4 wk and r = -0.44 in the 6 wk. In the middle of the diaphyses, decrease in vBMD was observed in both sexes in the 4 wk and 8 wk. Our research showed that changes in vBMD and BMC are disorders in the process of mineralisation. In both sexes, they caused reluctance to walk and increased the likelihood of deformities and fractures.
