This study aims to evaluate the effects of the inclusion of different homoeopathic products on the diet of laying quails. We used 200 Japanese quails (Coturnix coturnix japonica) distributed in a completely randomized design consisting of the adoption of four experimental diets, with eight replicates of five quails each. The treatments were control (without additives), calcium carbonate (vehicle used in the products), Fertsigo®, and Ovosigo®. We determined the performance, egg quality, and blood biochemical profile of quails. The data were submitted to Tukey test at 5% probability. There was a significant effect of the homeopathic products Fertsigo® and Ovosigo® on the variables egg weight, yolk, albumen, and shell percentage. It did not affect the performance and blood biochemical profile (p > 0.05). The addition of the homoeopathic product Ovosigo® and FertSigo® in diets of Japanese quails at the laying phase is recommended because they resulted in the better weight of the egg and its components. Thus, the application of homoeopathy in the production of quails is a viable practice, since it is easy to manage, has a reduced cost, and exerts positive effects on the performance of quails.
