Effect of Adding L-Arginine to Broiler Diets on Physiological Performance

Abstract

This research was conducted in the poultry sector of the Department of Animal Production, College of Agriculture, University of Anbar, from October 26, 2022, to December 7, 2022 (42 days). The objective was to compare the effects of incorporating different levels of L-Arginine and vitamin C on the productive and physiological performance of broiler chickens. One hundred and fifty Ross 308 strain broiler chicks, aged one day and of unspecified sex, were utilized in the study. The chicks were individually weighed and randomly assigned to five experimental groups, each consisting of three replicates with ten birds per replicate. The treatments consisted of the following: First treatment Control group (no additives), Second treatment: Addition of arginine at a rate of 1 g/kg of feed, Third treatment: Addition of arginine at a rate of 1.5 g/kg of feed, Fourth treatment: Addition of arginine at a rate of 2 g/kg of feed and Fifth treatment: Addition of vitamin C at a rate of 300 mg/kg of feed The results of the study revealed that utilizing the specified levels of arginine and vitamin C in the diets did not lead to any significant impact on the physiological performance, chemical, and biochemical blood parameters of the broiler chickens. These parameters included Glutathione, Malondialdehyde (MDA), Very Low-Density Lipoprotein (VLDL), Low-Density Lipoprotein (LDL), High-Density Lipoprotein (HDL), Triglycerides, Cholesterol, Creatinine, Uric Acid, AST (Aspartate Aminotransferase), ALT (Alanine Aminotransferase), Ceruloplasmin, Albumin, Protein, Glucose, H/L Ratio (Heterophil to Lymphocyte Ratio), Lymphocytes, and Monocytes. In conclusion, the utilization of the specified levels of arginine and vitamin C in the diets did not result in any significant effects on the studied parameters in the broiler chickens.
