Abstract

This work aimed to evaluate the steps of stunning and bleeding during slaughter of pigs, the effectiveness of the process and its implications upon the clinical signs shown after these procedures. It was checked the parameters of voltage, amperage, stunning time, clinical signs after stunning and bleeding, bleeding time and condemnations relevant monitoring of 499 pigs slaughtered in a slaughterhouse under State Inspection Service. The study revealed that 9.8% of the animals were anesthetized, which shows that was not provided a correct stunning using an instantaneous unconsciousness and painless to the animal. In post-mortem inspection of offal condemnation was also evaluated and quantified the loss of lungs, liver, heart and spleen. In a parallel assessment to the experiment, it was listed the condemnations of these organs in nine slaughterhouses registered in the State Inspection Service in the period from january to april of 2012, leading to a finding of an expressive economic loss due to rejection of products, either by a deficiency in the management of the animals, either by failures during the slaughter process.
