CONDENAÇÕES DE CARCAÇAS DE FRANGO DE CORTE EM SISTEMAS DARK HOUSE E CONVENCIONAL

Abstract

The objective of the work is to evaluate dark house and conventional production systems, in relation to carcass condemnation. The data for carrying out the work were provided by the company Qualliti Alimentos, 6 sheds containing 293,109 chickens in the conventional system and 6 sheds with 299,301 chickens in the dark house system were used for the analysis. The variables analyzed were divided into: composition of the two systems (average days of slaughter, number of birds per house and average weight per house) disposal by management (cachexia, foot callus, wing contamination and disgusting aspect of the carcass) disposal by disease (cellulite, ascites, pericarditis, septicemia and salpingitis) and disposal by mechanical action (skin, hematoma on the wings, hematoma on the thighs and hematoma on the chest). The shapiro-wilk test was performed and, subsequently, the analysis of variance through the SAS University program (2020), by the PROC ANOVA procedure, at the level of 5% of significance. After the study, it was observed that the characteristics analyzed that are involved in the disposal of parts or carcasses do not differ in terms of the type of system.
