Abstract

Food security is important, and is being increasingly focused on during animal production. In bovine carcasses, we can find hematomas that are the consequences of traumas caused by several factors. These cause the extravasation of blood from vessels, causing the blood to accumulate in muscular tissues, which can then serve as a substrate for bacterial proliferation. The objective of this study was to quantify the occurrence of hematomas in bovine carcasses and to determine their degree of severity, to measure the economic impact these hematomas can cause. The slaughter of 385 animals was monitored, and 56.88% showed some type of hematoma. In injured animals, there were a total of 427 lesions, with an average of 1.94 of injuries per animal. There was a total loss of 65.7 kg of meat, with following proportional distribution: 12.32% in the front room (8.1 kg), 33.18% near the ribs and the lumbar region (21.8 kg), and 54.49% (35.8 kg) in the hindquarter. The resulting economic loss was calculated to be a total of US $ 206.66 (R $ 817.93). We conclude that the occurrence of hematoma lesions in bovine carcasses from the north central mesoregion of Parana is responsible for economic losses.

Summary

Introduction

Matias et al Acta Veterinaria Brasilica September 13 (2019) 114-119 factors; among them are the stages of pre-slaughter, which includes farm management, transportation, and handling in the refrigerator. Of concern is the damage caused by inadequate pre-slaughter management, which is reflected in the carcass and manifested as contusions, vaccine abscesses, and other changes that are later removed in toilet These damage the carcass and decrease its value for both the producer and for the ones involved in its trade (ANDRADE, COELHO, 2010). Andrade et al (2009) report that inadequate preslaughter management reduces animal welfare; these authors report that the transport of cattle to the slaughterhouse has a great influence on the quality of the meat. Failures in this process cause various consequences in the carcass, such as bruises. It should be noted that according to the animal welfare rules established by the Ministry of Agriculture, Livestock and Supply, Chapter V, Article 14, bovine animals that are set for export are permitted to be transported by road for a maximum of 8 h (MAPA, 2017)
