The yolk of avian eggs contains steroid hormones, which may influence the development and behaviour of hatched birds. The aim of the present study was to investigate the concentration as well as the distribution of various gonadal steroids in the yolk spheres of quail eggs. Steroid concentrations of dissected yolk layers were analysed after alcoholic extraction using enzyme immunoassays (EIAs) for progesterone, androstenedione and testosterone. To monitor the uptake of testosterone into the… CONTINUE READING
