Dietary genistein supplementation enhances reproductive and bone health in late-laying hens.

ABSTRACT: Aging in laying hens leads to progressive declines in production performance and egg quality, primarily due to deteriorating ovarian function and bone health. Genistein, a natural isoflavone with anti-inflammatory and antioxidant properties, shows potential as a dietary intervention to alleviate age-related physiological decline. This study evaluated the effects of dietary genistein supplementation on ovarian and skeletal health in aging laying hens. A total of 180 Hy-Line Brown laying hens (60 weeks old) were randomly assigned to either a control group (CON) receiving a basal diet or a genistein group (GEN) supplemented with 20 mg/kg genistein for 15 weeks. Genistein significantly increased HDEP during 66-76 weeks of age, increased HHEP during 66-76 weeks of age, and improved eggshell qua
