Introduction: The aim of this study was to investigate the influence of diet supplementation with sodium butyrate and Yucca schidigera extract (0.2% and 0.3%) on femur quality of growing pigs (n = 45). Material and Methods: At the age of 28, 35 and 56 d, five piglets from each group fed a different diet were euthanised and the femora were collected for further analyses. The bone characteristics were assessed based on weight, length, densitometric analysis of BMC and BMD, pQCT analysis (area, mineral content, volumetric density of trabecular and cortical part of metaphysis and diaphysis, respectively), ultimate strength, and geometrical parameters (cross-sectional area and second moment of inertia). Results: There were no significant differences in femur bone parameters among experimental groups on the 28th d of life. On the 35th d of life, piglets with 0.2% supplementation of sodium butyrate and Yucca schidigera extract had significantly lower values of weight and second moment of inertia, and significantly higher trabecular BMD and BMC compared to other experimental groups. In 56-day-old pigs, the higher values were observed in both experimental groups regarding BMC, ultimate strength, geometrical parameters, cortical BMC, diaphyseal total area, and endosteal circumference (P < 0.05). Significant differences between experimental groups were observed only in bone weight and cortical thickness. Conclusion: This study proved that simultaneous supplementation with sodium butyrate and Yucca schidigera extract positively influences bone quality in pigs in the post-weaning period. However, there were no differences in bone characteristics between the addition of 0.2% and 0.3% preparations.
