الوصف: The effects of the restriction of the advised daily feed intake (ADFI) during 1 or 2 weeks on broiler body weight (BW) and carcass composition were studied. A total of 150 1-day-old male broilers (Ross-308) were randomly allotted to a control and four experimental treatments with three replicates per treatment. Broilers were subjected to a feeding restriction equal to 75 and 50 % of ADFI, either for a 7- or a 14-day period, between the 7th and 14th and 7th and 21th day of age, respectively. The BW and carcass composition were determined on day 42. From the findings, neither of the two levels of restriction nor the two time intervals had significant effects (P > 0.05) on the BW or breast and leg weight and proportion, liver and most of the body components. However, the feeding treatments show a tendency (P = 0.078) to influence the BW, with birds fed 75 % of ADFI for 14 day being heavier than the control group. For eviscerated carcass weight, an effect (P = 0.002) was observed, with birds fed 75 % of ADFI for 14 day having heavier carcasses (P < 0.05) than those in control group. The abdominal fat, both with regard to weight and proportion, was slightly influenced by dietary treatments (P > 0.05). From our results, it can be concluded that the applied feeding restrictions have a neutral or slightly beneficial effect on broiler growth traits and carcass composition.
