Resumo
The profile of the Brazilian cattle industry has changed due to the search for
more efficiency. It is transforming form extractive practices to new levels of
intensification and productivity. In this context, the metabolic and parasitological
profile of 39 crossbred animals, aged around 24 months at the time of entering
the feedlot and prior to slaughter were performed, in order to assess the health
of bovine finished in this breeding system. The following evaluations were
carried out: hematology, biochemistry, histopathology and parasitology. The
clinical biochemical evaluation consisted of the higidity assessment of the liver
and kidney, comprising the balance of energy and protein of these animals. The
parameters used were: ALP, AST, GGT, bilirubin (total, conjugated and
unconjugated), total protein, albumin, globulin, urea, creatinine, cholesterol and
triglycerides. Total proteins were fractionated by agarose gel electrophoresis.
Parasitological assessment was done through EPG and stool culture. In
histopathology fragments of liver, kidney, lynph nodes (mesenteric, pre scapular
and pre femoral) and lung were observed. Alterations in biochemical and
electrophoretic tests, suggestive of chronic liver disease, were found. Such
alterations were noticed by the presence of foamy macrophages in the liver and
mesenteric lymph nodes; however, these findings were not related to
differences found in daily weight gain found. Histology did not show alterations
suggestive of respiratory diseases.
