Highlights
The goal of this study was to assess the influence of simulated microgravity on morphological characteristics and mineral content of the long bones of the right leg of female Japanese quail chicks from 3 to 56 days of age
Other differences in femur and tibiotarsus mineral content between test and control group were not significant. These findings suggest that, hypodynamy reduce bone growth of test birds, the long bones of the right leg of female Japanese quail were able to develop under conditions of simulated microgravity
Several studies investigated the rate of long bone development (Starck 1996), only a few studies examined the effects of altered gravity on quail postnatal development (Boìa et al 1992; Sabo et al 2001)
Summary
The goal of this study was to assess the influence of simulated microgravity (hypodynamy) on morphological characteristics and mineral content of the long bones of the right leg of female Japanese quail chicks from 3 to 56 days of age. Other differences in femur and tibiotarsus mineral content between test and control group were not significant These findings suggest that, hypodynamy reduce bone growth of test birds, the long bones of the right leg of female Japanese quail were able to develop under conditions of simulated microgravity. The simulated microgravity caused reduction in mineral content of leg bones of adult Japanese quail as compared to control birds (S v ia tk o et al 1998) It is unknown, how simulated microgravity or long-duration space flight may influence the avian and human postnatal development during the subsequent ontogenetic phases.
