EFFECT OF DIETARY SUPPLEMENTATION WITH DIFFERENT LEVELS OF CREATINE MONOHYDRATE ON PRODUCTIVE AND CARCASS PERFORMANCE OF BROILER CHICKENS

Abstract

The study was conducted during the period from March 8th, 2017 to April 19th, 2017 at the Poultry Farm of Animal Sciences Department, College of Agricultural Sciences, University of Sulaimani to investigate the effects of dietary supplementation with different levels of Creatine Monohydrate on productive and carcass performance of broiler chickens. By using 300 one-day old of Ross 308 broiler chicks, divided into three periods with 4 treatments for each 3 replicates based on completely randomized design for 42 days. Feed and water were provided as ad libitum.Chicks were divided into four treatments for 3 periods (1-42, 28-42 and 35-42) days, control 30 birds and for each treatment 90 birds; each treatment for one period contained three replicates of 10 birds. Dietary Creatine Monohydrate was added to the diet from the first day to the end of experimental which lasted 42 days at levels of 0% (Control), for each period 0.05%(T1),0.075%(T2) and 0.1%(T3). The body weight had significantly (P<0.05) affected by Creatine Monohydrate supplementation at period (1-42), Creatine Monohydrate had a significantly (P<0.05) effect on weight gain at period (1-42), it had significantly (P<0.05), effect on breast meat yield at period (1-42). However, Creatine monohydrate had no significant effect on feed intake at the period (1- 42, 28-42 and 35-42), there was no significant effect on feed conservation ratio, mortality and Thigh meat yield at periods (1-41, 28-42 and 35-42). Creatine monohydrate had no significant effect on (body weight, weight gain, and breast meat yield) at periods (28-42 and 35-42).
