Performance, haemato-biochemical indices and antioxidants status of broiler chickens fed diet with low metabolizable energy supplemented with graded levels of Guanidino Acetic Acid (GAA)

Abstract The growth, haemato-biochemical indices, and antioxidant status of broiler chickens fed varying levels of Guanidino Acetic Acid (GAA) were evaluated over the course of an eight-week feeding trial. In low ME (2700Kcal/kg) basal diets, the Guanidino Acetic Acid was supplemented at 0, 0.6, and 1.2g/kg, designated as diets I, II, and III, respectively. The average final weight of chickens fed diet III was the highest at the end of the feeding trial. The best feed conversion ratio was observed in birds fed diet III. The packed cell volume and haemoglobin were highest in birds fed diet I. Significantly higher Cholesterol and Albumin were recorded in diets III and II, respectively. All the antioxidant parameters were significant except Catalase. The glutathione peroxidase increased with increased Guanidino acetic Acid supplementation while Catalase reduced with increased GAA supplementation. According to the findings of this study, Guanidino Acetic Acid improved the health of broilers while having no negative effects on their health. It is therefore concluded that supplementation of Guanidino Acetic Acid at 1.2g/kg with low metabolizable energy promoted superior growth effect of the chickens and also reduce cost of production.
