Effect of dietary stevia-based sweetener on body weight and humoral immune response of broiler chickens.

Background And Aim: Steviol glycosides extracted from the leaves of Bertoni have been of much consideration recently because of their beneficial effects on health, raising the possibilities for improving farm animals' health. Although some studies on stevia's dietary effect on body weight gain are available, few studies have been conducted to evaluate stevioside supplementation on immune response in broilers. This experiment aimed to analyze how a stevia-based sweetener can affect broiler chickens' growth performance and humoral response.
