This study was carried out to evaluate the effects of physical feed restriction method with different intensity and duration on broiler performance. One hundred and fifty Ross-breed 308 male broiler chicks in a completely randomized design were divided into five experimental treatments. The treatments included physical limitations by 25% or 50% of recommended amount on feed of broilers in two periods of 7 or 14 days. One control group was used fed ad libitum. Each limitation’s severity level was applied in τηρεε replications of 10 birds. All experimental treatments before and after the limitation period until slaughter (day 42) were fed ad libitum. The results showed that in total period broilers under the physical limitation of feed had significantly lower feed intake than controls (P < 0.05). In this research, methods and levels of physical restriction intensity and duration of feed had no significant effect on body weight for the whole experimental period. Methods and levels of food restriction severity and duration had significant effect on feed efficiency (P < 0.05). (EN)
