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

Abstract

Abstract The present work was aimed to study the effect of L-arginine level to dietary, this study was conducted in the poultry field of the Animal Production Department at the College of Agriculture / University of Anbar for the period from 10/26/2022 to 12/7/2022 (42 days), with the aim of studying the comparison of adding different ratios of L-Arginine and a percentage of vitamin C in Productive and physiological performance of broiler chickens. In the study, 150 broiler chicks (unsexed) Ross strain (308) were used in the study, at the age of one day. They were individually weighed and randomly distributed to five experimental treatments, with three replications per treatment (10 birds replicated). First treatment is control with not addition, second treatment included the addition of L-Arginine at a rate of 1g/1kg of feed, third treatment included the addition of L-Arginine at a rate of 1.5g/1kg of feed, fourth treatment included the addition of L-Arginine at a rate of 2 gm / 1 kg of feed and fifth treatment included the addition of vitamin C at a rate of 300 mg / 1 kg of feed. The results of the production performance study and the economic indicator showed that the use of the above-determined ratios of arginine and vitamin C in diets had no significant effect on weight gain, body weight, feed conversion factor, and mortality at (P≤0.05).
