PREVALENCE OF HEPATIC ALTERATIONS IN CATTLE SLAUGHTERED IN THE CITY OF PRESIDENTE PRUDENTE, SAO PAULO STATE/PREVALENCIA DE ALTERACOES HEPATICAS EM BOVINOS ABATIDOS EM MATADOURO-FRIGORIFICO DO MUNICIPIO DE PRESIDENTE PRUDENTE, ESTADO DE SAO PAULO/PREVALENCIA DE LAS ALTERACIONES HEPATICAS EN LOS GANADOS SACRIFICADOS EN MATADERO DE LA CIUDAD DE PRESIDENTE PRUDENTE, ESTADO DE SAO PAULO

It is fundamental the knowledge about predominance of hepatic lesions, to monitor them and supply material to the preventive veterinary medicine actions, thus improving the production process, reducing economic losses. In this work were catalogued morphological alterations in livers of slaughtered bovines from an abattoir under Federal Inspection Service in Presidente Prudente, Sao Paulo State, during the period of April 01 2010 to March 31 2011. The lesions were catalogued according categories: degenerative, vascular, inflammatory, extra hepatic, parasitary and neoplasic. To classify the alterations, was considered fundamentally characteristics like color, texture and hepatic parenchyma consistency. Were inspected 100,723 animals, which 72,638 (72,12%) males and 28,085 (27,88%) females. 5,204 (5,17%) from total showed some kind of hepatic alteration. Most significant alterations group was inflammatory, including hepatitis, perihepatitis and suppurative lesions (34,69%). Second most representative group was vascular alterations like telangiectasis, capsular hemorrhagies and passive congestion (31,80%). Liver condemnation by extra-hepatic causes is high, mainly associated to organ secondary contamination. The fasciolosis was observed in 29 parts of liver (0.56%), suggesting that this parasitosis is adapted to the region, drawing attention to its zoonotic potential and to being an emerging parasitosis.
