Abstract

The objective of this study was to evaluate the effects of the different quantitative feed restriction programs on the productive and economical performance of broiler chickens. Two hundred and sixty four broilers distributed in a completely randomized design, with six treatments, four replications and ten birds per replication were used. The feed restriction (FR) programs were: T1 – ad libitum; T2 – FR at 8th day of age; T3 – FR at 8th and 13th days of age; T4 – FR at 8th, 13th and 18th days of age; T5 – FR at 8th, 13th, 18th and 23th days of age; T6 – FR at 8th, 13th, 18th, 23th and 28th days of age. Evaluating the total period the feed restriction program did not influence the productive performance (feed intake, feed:gain ratio and weight gain) of the birds. Nevertheless, the T6 animals reached smaller live weight at 42 days of age in relation to T1 and T2. In relation to the financial indicators, the broilers of the T1 presented greater average gross income (AGI) and relative profitability index (RPI) while the T6 resulted in smaller AGI and RPI values. Considering the results to performance and economical indicators parameters presented in this study, no reasons were found to justify the adoption of feed restriction programs in male broiler chickens from Cobb strain.
