Abstract
This study is conducted to find out the effect of the gradual increase of lighting intensity and its effect on the productive performance of broilers. In this study, 224 one-day-old Ross 308 broiler chicks were randomly distributed into 4 treatments with 4 Replicates for each treatment i.e. Replicates The treatments Of The Experiment: T1 the lighting program according to the guide for 308 ROSS company (Control Treatment), T2 the lighting program according to the guide with a gradual increase of lighting intensity every 20 minutes, T3 the lighting program according to the guide with a gradual increase of lighting intensity every 40 minutes, T4 Lighting program according to the guide with a gradual increase of lighting intensity every 60 minutes.
The productive performance features Were Studied Weekly and at 1-21 ,21-35,1-35 Days. The results of the study show a significant superiority of all experimental treatments in the average body weight and weight gain compared with the control treatment at the third week as well as the period from 1-21 days. It is also noted that the fourth treatment has a significant superiority at the rates of consuming feed compared with the control treatment. Besides, the second treatment is significantly greater at the relative growth rate compared with the control treatment at the second week and at the period from 1-21 days as well. Even though it does not differ significantly at the end of the experiment.
It is also concluded that there is no significant difference among the treatments in both; food conversion factor and the percentage of Mortality. Finally, it is observed that there are no significant differences in all characteristics of the cumulative productive performance among all treatments from 1-35 days. So, it is regarded as an important indicator in the productive performance leading to the outcome that no significant effects of the gradual intensity of lighting on the productive performance of broilers.
