Laying hens, particularly egg-type chicks, are at risk of heart issues due to dietary selenium (Se) insufficiency, which has been shown to affect cardiac health in broiler chickens.
In this study, White Leghorn chicks were fed diets either lacking in Se or supplemented with it, revealing significant differences in heart health and body weight, with Se-deficient chicks showing signs of cardiac inflammation and reduced selenoprotein expression.
The research indicates that a lack of selenium leads to increased inflammatory markers and oxidative stress in the hearts of these chicks, highlighting the critical role of Se in maintaining cardiac health early in life.
