Caracterización de las canales dictaminadas como caquexia, durante la inspección sanitaria en planta de benefició de pollos de engorde.

Abstract

In the Poultry Processing Plant, the seizures of carcasses unfit for human consumption represent between 0.5 and 0.6% of the birds transported annually, of these, 0.32% are birds determined by macroscopic inspection as cachexia. Through the characterization of these seizures, the aim is to identify predisposing factors, bird characteristics and/or spatial or linear behaviors that directly interfere with their presentation; Macroscopic aspects of 141 seizures with cachexia were studied, each one was monitored and according to the condition of the carcass, classified in degree of affectation from 1 to 3, being 1 mild, 2 moderate and 3 severe. 40 carcasses were sampled for microbiological analysis in the processing plant and a retrospective analysis was made with the company's database from the year 2021 for the analysis of the incidence and prevalence of seizures for this reason, 29.11% of the seizures carried out between the year 2021 and May 2023 were due to cachexia, 59% belong to the RossAp genetic line; 50.2% of the seizures due to cachexia were female birds. There is no evidence of linear behavior in the incidence of this seizure; the Lebrija area presents the highest prevalence of cachexia. 3% of the inspected cachexia were classified as type 1, 39% type 2 cachexia and 58% type 3; 67% of the seizures due to cachexia had other simultaneous diseases, mainly cyanosis. In the microbiological analyses, E. coli was isolated.
