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 86.50±2.78%, 32.84±1.50%, 27.71±1.44%, and 13.21±0.94%, respectively. Shear force, pH, water holding capacity, lightness, redness and yellowness means and standard deviations were 1.92±0.98 kgf.cm-2, 6.07±0.12; 70±0.53%, 48.30±0.96, 1.96±1.01, and 1.61±1.0, respectively. Moisture, ash, crude protein, fat, and cholesterol contents were 72.35±0.16%, 1.12±0.06%, 25.53±0.50%, 0.17±0.01%, and 18.87±2.76 mg/10g, respectively. Results showed carcass and parts yields and the physical-chemical traits of tinamou meat are similar to chicken meat; however, tinamou meat is less acidic and has higher protein level combined with less calories and lower cholesterol levels.
Highlights
The red-winged tinamou (Rhynchotus rufescens) is a native bird of the Brazilian fauna and can be found in rural areas, savannahs, and open uplands
Its reproductive season lasts from September to March and it is characterized by the fact that the males incubate the eggs until hatching and are responsible for chick care (Sick, 1997)
In order to increase the scientific knowledge on the species, this study aimed at evaluating carcass and parts yields, as well as meat physicalchemical characteristics of red-wing tinamous
Summary
The red-winged tinamou (Rhynchotus rufescens) is a native bird of the Brazilian fauna and can be found in rural areas, savannahs, and open uplands. It is the largest bird among the rural species of the Tinamiformes order. Its reproductive season lasts from September to March and it is characterized by the fact that the males incubate the eggs until hatching and are responsible for chick care (Sick, 1997) It was traditionally the favourite bird for sport hunting in Brazil due to its short and low flight, and because it inhabits fields with low vegetation, allowing the use of hunting dogs and good shooting conditions. There have been some initiatives to breed the tinamou for commercial and preservation purposes, since population numbers are declining due to extensive occupation of the savannahs by cattle herds and the Brazilian taste for their meat
