This study aimed to determine the effect of dietary restriction on certain production and microbial traits of broiler chickens. A total of 210 one-day-old, unsexed Ross 308 commercial hybrid chicks, with an average initial weight of 40 g, were used in the study. The experiment was divided into seven experimental treatments, each consisting of 30 birds, with three replicates per treatment (10 birds/replicate), yet. The final results of the experiment showed a highly significant improvement (P≤0.01) in final body weight and weight gain, as well as a significant difference (P≤0.05) in feed consumption and overall feed conversion efficiency and production index values. Additionally, a considerable superiority (P≤0.05) was observed in the dressing percentage and the logarithmic counts of Lactobacilli bacteria, along with a significant decrease in E. coli bacteria across all restricted treatments when compared to the control treatment. Treatments T3 and T2 achieved the best results among the restricted treatments.
