This study aimed the effect of different periods of early fasting on productive and economic traits of broiler. A total of 180 chicks of the ROSS 308 were used, one day, 43 g average weight, were randomly distributed into three treatments, as follows; the first treatment (T1) free feeding from one day until the end of the experiment (6 weeks) as a control treatment, the second treatment (T2) was lifted feed two days apart per week during the period of food rationing starting from 7-21 days, and the third treatment (T3) was provided feed between one and the other reciprocally during the same time rationing period, after the end of the fasting period in the second and third treatment at the age of 21 days, it was provided for brood rearing until the 6-week marketing date.
