Abstract: 

Eight hundred and sixty four-day old Ross 208 broiler chicks were randomly assigned to three treatments. There were 3 stocking densities of 14, 16 and 18 birds/m2 (treatments 1, 2, 3 respectively). Two high densities were reduced to 14/m2 at 6 weeks of age. Each pen (4.5m2) had one cylinder waterer and feeder. All birds received common feed and management for 49 days. Body weight, feed intake, feed conversion ratio (FCR) and mortality were determined at 21, 42 and 49 days. Data for all response variables were subjected to ANOVA. Variable means for treatments showing significant differences in the ANOVA were compared with Duncan's multiple range test. Reducing the stocking density from 18/m2 or 16/m2 to 14/m2 at 6 weeks increased food consumption and body weight gain and led to compensatory growth in their body weight by 7 weeks.
According to the results of this experimental trial, it could be concluded that for obtaining the best performance of flock, breeding period with high density and reducing density at 42 days could be a good strategy to achieve a good performance in breeding period.
