Origem das condenações de carcaças de frangos de corte

Abstract

The Brazilian poultry industry stands as the largest exporter of chicken meat in the world with an incisive performance by the Federal Inspection Service (SIF). The objective of the study was to identify the factors that affect the incidence of condemnation visualized in the post mortem of broiler chickens, with a pre-slaughter fasting as the dividing point. In this way the origin of these condemnations as being before or after the chicken is ready for the slaughter. Wrong handling done since pre-slaughter fasting, being due to faults in the maintenance of the equipment or by essentially human, are called Technopathy. For this purpose, the data of condemnation and slaughter of birds were collected at an establishment located in the SIF, located in the Grande Dourados/MS region, with a slaughtering capacity of 120,000 birds/day from 2004 to 2014. The birds were housed in aviary positive pressure and slaughtered aged 28 to 34 days, with carcasses of 700 to 1400g, without the kids. Fasting took place, on average, nine hours before slaughtering, and it was collected in full manual and with the assistance of the technician. The data analyzed were mean total and partial convictions per year; the rate of occurrence and proportion of convictions (IOC) for every thousand birds slaughtered, and the rates of pre-and post-fasting convictions, which were dismembered by calculating the frequency of convictions to verify the main causes of convictions. Conviction rates (%) and IOC were higher after fasting (P<0.05). Among the partial condemnations prior to fasting, acne was the most frequent (34.45%), while among the total, the main one was colibacillosis (14.34%). After the fast, the contamination was the type of partial condemnation that stood out, with a frequency of 66.92%. There was no standard behavior for the total contamination attributed to the management after fasting. It was concluded that the highest proportion of condemnations occurred after the birds fasting, with the main diagnosis being the contamination and, about the causes of condemnation before fasting, the dermatosis was the main cause.
