The present study evaluated the influence of genotype and rearing system on the performance of alternative lines of broiler chickens. Two experimental lines (Caipirinha and 7P) and two commercial lines (Label Rouge and Paraíso Pedrês) were reared under intensive or semi-intensive (access to the pasture area after 21 d of age) in an experiment with eight treatments, four replicates and 35 birds per experimental unit. Corn-soybean meal based feed and water were offered ad libtum in the pen area only, […]
