Meat and carcass traits of the red-winged tinamou (Rhynchotus rufescens)

Abstract

Tinamou (Rhynchotus rufescens) is a native bird of the Brazilian fauna and has great potential to become a domesticated species. From this perspective, the objective of this study was to evaluate the carcass and main parts yield and to assess meat quality of that bird. Two trials, one studying stocking density and the other litter materials, lasting 60 days each, were conducted. The studied traits were evaluated in two birds/ replicate/treatment. Performance was evaluated by the least square method. The results showed that bird age at slaughter significantly influenced carcass and breast yields (p<0.05). Mean carcass, breast, thighs+drumstick and wing yields were 86.

Effect of Litter Substrates on the Performance, Carcass Traits, and Environmental Comfort of Red-Winged Tinamou (Rhynchotus Rufescens)

“…The average breast yield obtained in the present experiment was 31.79 (± 0.29) %; which is lower than those reported by Queiroz et al (2013) and Moro et al (2006), of 33.72% e 36.6%, respectively. The effect of age on breast yield is an indication that the growth of the breast muscles is associated with secondary sexual differentiation of flightless birds.…”

“…Moro et al (2006) reported a lower value, of 74.4%, in redwinged tinamous (Rhynchotus rufescens) submitted to different feeding programs, whereas Queiroz et al (2013), evaluating rearing density, obtained 85.48% average carcass yield in this same species.…”

Caracterização dos componentes internos e qualidade dos ovos de perdiz brasileira (Rhynchotus rufescens) durante 28 dias de armazenamento

“…A criação racional da perdiz brasileira (Rhynchotus rufescens) tem ganhando notoriedade por sua fácil adaptação ao cativeiro e resultados produtivos promissores. Apesar de ser uma ave em processo de domesticação, apresenta bons índices de desempenho (Moro et al, 2000;Tholon & Queiroz, 2007), rendimento de carcaça (Moro et al, 2006;Queiroz et al, 2013) e adaptabilidade a novas dietas (Felipe et al, 2010;Moro et al, 2002;Nakage et al, 2002). Sua exploração zootécnica visa a produção de cortes cárneos exóticos, mas em tempos que se buscam fontes alternativas de proteína animal e ovos cada vez mais diferenciados no mercado, é importante que se explore a potencialidade dessa espécie para a produção de ovos.…”

Genetic and Environmental Effects on Tonic Immobility Duration of Red-Winged Tinamou Applying Survival Analysis

“…Despite being wild, their domestication has attracted great interest due to their high cynegetic value, and excellent carcass yield, particularly breast yield (Queiroz et al, 2013), as well as remarkable adaptation to commercial feeds (Hoshiba et al, 2003). Therefore, aiming at supplying a consumer market for exotic meats, this species could be reared under similar commercial conditions as broilers.…”
