SUMMARY:

Bovine Euritrematosis in Brazil is caused by Eurytrema coelomaticum, a trematode of pancreatic ducts in ruminants, predominantly in the southern states. Macroscopic pancreatic lesions were related to pancreatic atrophy, fibrous interstitial pancreatitis, and total or partial pancreatic duct obliteration. It is conjectured these lesions may cause disorders in the secretory functions of the pancreas, digestive and metabolic processes dependent on them. The aim of this work was to determine if there is a decrease in the digestibility of nutrients, serum, hematological and fecal changes in parasitized cattle correlated with parasite burden. Pancreas and respective blood and fecal samples from 119 bovines, belonging to different breeds and from different rural properties, collected in the municipal slaughterhouse in Concórdia-SC, were used. Stool samples were kept at 4ºC until they were subjected to gelatin digestion tests in a tube and radiographic film digestion. The following biochemical tests were performed: amylase, lipase, glycemia, fructosamine, cholesterol, triglycerides, total proteins, albumin, and globulins. After that, the biochemical analyzes were correlated with the numerical quantity of parasites found in the pancreas (post-mortem). The prevalence of euritrematosis in the region was approximately 60%. There was a greater amount of negative tests in animals with high parasitic load both in the radiographic film digestion test and in the gelatin digestion test (p <0.001), when compared to non-parasitized animals and those with low parasitic load, demonstrating changes in the above mentioned exams only if the number of parasites is significantly high. The activities of the enzymes amylase and lipase were significantly higher in animals with low parasitemia (p <0.05), compared to animals with high parasitic burden and non-parasitized. Also, animals highly parasitized by E. coelomaticum demonstrated hyperproteinemia due to hyperglobulinemia (p <0.05), correlating this with the inflammatory response with the formation of antibodies. It is concluded that in cases of high parasitemia, there is a significant change in the tests of digestion in feces and that in cases of low parasitemia there are significant changes in the values of serum amylase and lipase, both proving biochemical changes in the pancreatic profile, according to parasitemia.
