The objective of this work was to evaluate, at 42 days of age, the productivity and economic performance, and the carcass and special cuts yield, in broiler chickens allotted to different quantitative feeding restriction programs applied in early age. A completely randomized design was used, in a 5 x 2 (feeding restriction program versus sex) factorial arrangement and five replicates with 20 birds per experimental unit. Feed intake and weight gain were reduced by the feed restriction programs, but feed: […]
