The aim of the study was to investigate the changes in bone geometry, histological structure, and selected mechanical characteristics in young male and female Japanese quails supplemented with Saccharomyces cerevisiae. Quails were fed a basal diet containing no yeast or a basal diet supplemented with 1.5% (15 g per 1 kg of diet) of inactive S. cerevisiae, for a period of 42 days. S. cerevisiae inclusion had no effect on bone weight, length, and density, diaphysis geometry (cross-sectional area, wall thickness, moment of inertia) or on the mechanical strength (yield load, ultimate load, stiffness, Young’s modulus, yield stress, ultimate stress). Yeast supplementation improved the morphology of the articular cartilage both in male and female quails, as the total thickness of the articular cartilage was significantly increased. In trabecular bone, an increase in real bone volume and trabecular thickness was observed in females supplemented with S. cerevisiae, while in males the increase in trabecular number was accompanied by a reduction in trabecular thickness. The results of the present study demonstrate that S. cerevisiae, through a sex-dependent action on the gut-bone axis, improved the structure of articular cartilage and microarchitecture of trabecular bone. The positive effects of S. cerevisiae supplementation were more evident in female quails.
