Avaliação da carcaça de frango caipira produzida no município de Sumé- Paraíba.

Abstract

This study aimed to evaluate the chicken skeleton produced in the system semi intensive in municipality of Sumé-Paraíba. We evaluated twenty birds of the lineage CPK and ten females and ten males, where the animals were kept in semi confinement for a period of ninety one days. The birds were slaughtered with an average weight of 3.015Kg. Several variables were analyzed, such as: the initial weight, final weight, warm skeleton weight, skeleton yield of hot, income of commercial cuts and offal, analysis of temperature and analysis of pH. Being obtained the following results for skeleton yield: weight (Kg). Male slaughter 3.45, 2.58 females, skeleton weight (kg) 2.69 male, female 2.01, chest (%) 23.87 male, female 26.89, rib (%) 30.08 male, female 29.48, thigh (%) 14.77 male, female 13.31, thigh (%) male 14.78, 14.45 female, asa (%) male 5.17, 5.36 female, elena of asa (%) 5.41 male, female 5.43, skeleton yield (%) 77.04 male, female 76.16. For the evaluation of Post Mortem temperature and pH of the housings obtained the following medias. Final temperature after: 2.41 female, male 2.45. Final pH after: 5.995 Female, Male 6.12. Therefore, the results obtained in the experiment are satisfactory when compared with the literature cited in the course of work. It is observed the influence of sex on skeleton yield of total, where the male had a higher percentage, but in relation to the yield of commercial cuts, as the chest, the female stands.
