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.

An experiment was run using 720 male Ross chicks, grown from 22 to 42 days of age under high environmental temperature condition (26.2 to 30.5oC), to evaluate the effect of the digestible arginine:lysine (Arg:Lys) ratio on performance and carcass quality of broiler chickens. A complete randomized design with six treatments (95.0, 102.5, 110.0, 117.5, 125.0 and 132.5% Arg:Lys ratio), six replicates and 20 birds per experimental unit was used. There was no significant effect on broiler performance, however Arg:Lys ratio linearly improved leg quarter yield and linearly decreased abdominal fat.
