Aspectos produtivos relacionados a lesões em carcaças de bovinos e suas perdas econômicas em frigorífico comercial

Abstract

The bruises in animal carcasses are a reality present in the country's refrigerators, causing damage to both the producer and the industry. One of the ways to evolve in increasing productivity is to perform a mapping of the hematomas present in bovine carcasses and quantify the possible economic losses. The objective of this study was to estimate the occurrence of lesions in bovine carcasses in a commercial refrigerator and the economic consequences arising from this scenario. The work will be carried out in a refrigerator, located in Recife-PE. The study comprised 10 random days of data collection, where the boning of 2500 cattle quarters was followed, 800 females and 1700 males, and it was possible to monitor the boning of 2100 rear quarters and 400 front quarters. To record the occurrences, a form developed especially for this purpose was carried out. The results found showed that of the 2500 cattle rooms evaluated, 20.04% had some type of injury, with 398 of the lesions found in males (79.44%) and 103 females (20.56%). Evaluating the economic losses, during the experimental period, it can be observed that the total losses from injuries in kilograms was 88.17 Kg in 2500 rear, and only 501 (20.04%) presented injuries, so the losses during the 10 days was 0.176 Kg/quarter. It can be concluded that the situations to which animals are exposed until the moment of slaughter have an intense impact on the productive and behavioral parameters.
