Evaluation of the epidemiological bovine enzootic haematuria associated with prevalence of bracken fern in Paraná state

Abstract

The Bovine Enzootic Haematuria is a disease resulting from bracken fern intake, affecting animals in almost all states of Brazil. Due to economic losses and the risk to public health, research continues looking for ways to control plant and illness, as there are still places where cattle are created in direct contact with the plant, mainly in the state of Parana. In another perspective, many field workers engaged in awareness among farmers that continue to challenge the science, believing enzootic haematuriahas no direct relationship with the bracken fern. They suggest other etiologies, argue homemade prophylaxis and live therapeutic empiricism. Meanwhile, this plant is still present in several municipalities and the manifestation of characteristic and peculiar hemorrhagic in cattle grows visibly. This situation is very present in places occupied by cattle where the topography is quite rugged, with no possibility of land mechanization. Allied to this, there is evident lack of government policy in providing subsidiary liming the soil to correct the acidity caused by excess aluminum. Thus exposed, in a comprehensive study on municipal districts, bracken fern holders in their pastures, the authors correlated the existence of the plant to natural manifestation of Bovine Enzootic Haematuria for, a future and timing, get sensitize farmers to control plant, the disease elimination and increased safety public health, consumer of animal by-products such as meat and milk
