Turkish Journal of Veterinary & Animal Sciences

The effects of dietary boric acid (BA) supplementation on feed consumption, feed efficiency, egg production, egg weight, eggshell thickness, eggshell breaking strength, and some serum parameters (Ca, P, and Mg) were examined in 100 layer hens at 60 weeks of age. Commercial corn-soy-based layer diets were formulated as basal diets for the control treatment. Basal diets were supplemented with 25, 50, and 100 mg/kg BA (H_3BO_3), respectively, in experimental groups I, II, and III. In total, 4 dietary treatments were employed in the experiment. The experiment lasted 75 days. Feed efficiency and egg production values were not affected significantly by …
