Introduction: This research assessed the impact of adding Moringa oleifera leaf and seed to the diet of laying hens on their nutritional status and reproductive performance. Methods: Twenty one (21) week-old laying hens were randomly divided into seven groups of three birds. The control group was fed Layers' Mash, whereas the experimental groups were given a control diet supplemented with 5%, 10%, or 20% Moringa oleifera leaves and seeds. This feeding lasted six weeks. Eggs, meat and blood samples were analysed for nutritional quality evaluation and effect on some common reproductive hormones using appropriate standard protocols. Results: The present study revealed statistically significant (P < 0.05) differences in the internal and exterior properties of chicken eggs across groups. Compared with those in the control group, the concentrations of serum follicle stimulating hormone (FSH) and luteinising hormone were found to increase at some supplementation doses. Compared with those in the control group, significant (P < 0.05) increases in the serum total protein, albumin, ferritin, vitamins, and certain minerals were detected at different concentrations. Compared with those in the control group, significant (p < 0.05) changes in the dry matter content, energy content, ash content, ether extract content, albumen height of the bird meat and haematological parameters were detected. Conclusion: The addition of Moringa oleifera leaf and seed to the diet of laying birds increases their nutritional condition and reproductive performance, making it highly recommended.
