EXAME MACROSCÓPICO DAS ARTICULAÇÕES DE SUÍNOS ARTRÍTICOS NO ABATEDOURO

Resumo

Realizou-se um estudo macroscópico das articulações dos membros torácicos e pélvicos e respectivos linfonodos de suínos recém-abatidos em um matadouro localizado em Concórdia SC. incluiu-se no presente estudo todos os suínos que foram desviados da linha de abate, por suspeita de artrite. Dos 23.393 suínos abatidos, 140 (0,5%) foram desviados para o departamento de inspeção final, por suspeita de artrite. Deste total constatou-se: 70% de artrite causada pela osteocondrose, 21% artrite infecciosa, 3% artrite infecciosa e osteocondrose simultaneamente, 1% apresentaram artrite traumática, 3% artrite sem diagnóstico conclusivo e 2% apresentaram-se com as articulações normais. As artrites causadas pela osteocondrose caracterizaram-se pelo grande volume de líquido sinovial e pelas áreas focais de dobras, abas e úlceras na cartilagem articular. As artrites infecciosas caracterizaram-se pela reação nos linfonodos regionais e pela moderada a acentuada hipertrofia da membrana sinovial. O percentual de artrite causada pela osteocondrose foi superior ao encontrado em estudos anteriores e ressalta a necessidade de um diagnóstico diferencial com as artrites infecciosas a fim de se evitar a condenação desnecessária de carcaças.

Macroscopic analysis of joints from arthritic swines pigs in the abattoir

Abstract

A macroscopic study of thoracic and pelvic limb articulations as well as regional lymph nodes was performed in recently-slaughtered swines at a slaughterhouse located in Concordia, SC, Brasil. A total of 23,393 carcasses were included in the study, 140 (0.5%) being diverted on the discharge line by the Department of Final Inspection as suspicious for arthritis. The analysis of the suspicious carcasses showed that 98 (70%) presented arthritis caused by ostechondrosis, 29 (21%) infectious arthritis, four (3%) infectious arthritis and ostechondrosis simultaneously, two (1%) traumatic arthritis, four (3%) presented arthritis with uncertain diagnosis and three (2%) showed normal articulations. The arthritis caused by the osteochondrosis was diagnosed by the increased volume of sinovial fluid and focal areas of folds, flaps and ulcers in the articular cartilage. The infectious arthritis was diagnosed by an inflammatory process involving regional limph nodes and by moderate to accentuated hypertrophy of the sinovial membrane. The percentage of arthritis caused by osteochondrosis was higher when compared to those found in previous studies. This fact emphasizes the need for a differential diagnosis between infectious arthritis and osteochondrosis in order to avoid the unnecessary condemnation of carcasses at slaughterhouses.
