Doenças de bovinos no Sul do Brasil: 6.706 casos
As doenças que acometem bovinos na regiĂŁo Sul do Brasil foram analisadas atravĂ©s de um estudo dos protocolos de necropsia de 6.706 bovinos examinados pelo LaboratĂłrio de Patologia Veterinária da Universidade Federal de Santa (LPV-UFSM), Rio Grande do Sul, de 1964-2008. Desses, 20,9% foram necropsias realizadas no LPV-UFSM e 79,1% foram amostras de tecidos submetidos por veterinários de campo. Dos 6.706 exames, 62,9% tinham diagnĂłstico conclusivo. A autĂłlise ou material insuficiente foram as principais razões para a ocorrĂŞncia de casos com diagnĂłstico inconclusivo. A intoxicação por Senecio spp. foi a principal causa de morte de bovinos neste estudo. As plantas tĂłxicas e as toxiinfecções juntas, responderam por 22,8% dos casos com diagnĂłstico conclusivo. As doenças inflamatĂłrias e as parasitoses juntas contribuĂram com mais de 30% das doenças de bovinos e a tristeza parasitária bovina foi a principal doença nessa categoria. As demais categorias distribuĂram-se na seguinte ordem: neoplasmas e lesões tumoriformes (13,87%), doenças causadas por agentes fĂsicos (2,7%), doenças metabĂłlicas e nutricionais (2,46%), distĂşrbios circulatĂłrios (1,4%), doenças degenerativas (1,1%), distĂşrbios do desenvolvimento (0,54%), distĂşrbios iatrogĂŞnicos (0,16%), distĂşrbios imunogĂŞnicos (0,19%) e, outros distĂşrbios (0,21%). A alta prevalĂŞncia de tumores em bovinos foi atribuĂda a ingestĂŁo crĂ´nica de Pteridium aquilinum, uma toxicose comum na regiĂŁo. As principais doenças de bovinos na regiĂŁo estudada estĂŁo relacionadas a fatores ambientais resultante do manejo caracterĂstico de criação predominantemente extensiva adotado na regiĂŁo.The diseases affecting cattle in southern Brazil were studied through a review of the necropsy reports filed at the LaboratĂłrio de Patologia Veterinária of the Universidade Federal de Santa Maria (LPV-UFSM), Rio Grande do Sul, and pertaining to the examination of 6.076 cattle during 1964-2008. Of those exams 29.9% were necropsies performed at the LPV-UFSM and 79.1% were mailed-in organ fragments from necropsies performed at the field by veterinary practitioners. Autolysis and non-representative sampling o mailed in organs were the main reasons for non-conclusive diagnosis. Poisoning by Senecio spp. was the main cause of death in cattle in this study and poisonous plants together with toxi-infections accounted for 22.8% of the cases with conclusive diagnosis. Inflammatory diseases together with parasitic diseases accounted for more than 30% of cattle diseases and babesiosis and anaplasmosis were the main diseases in this category. Other categories were distributed in the following order: neoplasms and tumor-like lesions (13.87%), diseases caused by physical agents (2.7%), metabolic and nutritional diseases (2.46%), circulatory disturbances (1.4%), degenerative diseases (1.1%), developmental disorders (0.54%), iatrogenic diseases and sundry lesions. The high prevalence of tumors in cattle in this study was attributed to the chronic ingestion of Pteridium aquilinum, a common toxicosis in the region. The main diseases in cattle from the studied region are related to environmental factors associated to the predominantly husbandry practices adopted in the region
