The objective of this work was to evaluate performance and carcass and dressing yields of four broiler chicken lineages raised in confined and semi-confined systems. It was used 1,440 chicks distributed in a random block design with a 4 õ 2 factorial scheme, composed of lineage types (Ross 308, Máster Griss, Label Rouge and Vermelhão Pesado) and two production systems (confinement and semi-confinement), each one with four replications with 45 birds. At 84 days of age, four birds of each […]

The effect of strain, breeding system and sex on body weight, carcass and leg yield, and morphologic aspects of skeletal muscle fibers of flexor hallucis longus muscle of broiler chickens was evaluated in this study. The experiment consisted of a 4x2x2 factorial arrangement of treatments, with four strains (Ross-308, Naked Neck Label Rouge, Caipirinha and Paraiso Pedrês), two breeding systems (confinement and semi-confinement) and two sexes, with two replicates per treatment, considering each bird selected randomly at 56 days of […]
