The Revista Brasileira de Zootecnia (RBZ) is a publication dedicated to the broad field of Animal Science. We publish high-quality, original scientific research that spans across diverse areas within the discipline. The scope of RBZ encompasses a wide range of topics, including aquaculture, biometeorology and animal welfare, forage crops and grasslands, animal and forage plants breeding and genetics, animal reproduction, ruminant and non-ruminant nutrition, meat science and muscle biology, precision livestock, and animal production systems and agribusiness.

The objective was to evaluate body weight, leg weight and morphologic aspects of the muscle fibers of the flexor hallucis longus muscle and electrophoretic profile of myosin heavy chain of four strains of broilers, reared in confinement and semi-confinement systems. 1440 chicks were randomly assigned in a 4 × 2 factorial arrangement: four strains (Ross 305, Master Gris, Label Rouge and Vermelhao Pesado), two production systems (confinement and semi-confinement), with four replicates for each treatment. Four birds were sacrificed for […]

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 […]
