RESUMO:

Bovine Euritrematosis is caused by a trematode (Eurytrema coelomaticum) that mainly parasites the pancreatic ducts in ruminants, predominantly in the southern states of Brazil. Macroscopic pancreatic lesions were related to pancreatic atrophy, fibrous interstitial pancreatitis, and total or partial obliteration of the pancreatic ducts that may cause disorders in their secretory functions. In this context, it can be assumed that the digestive and metabolic processes dependent on pancreatic functions may be impaired and animals with pancreatic lesions may present decreased nutrient digestibility, which may cause serum, hematological, fecal changes and decreased feed conversion. The objective of this project was to evaluate the pancreatic profile of cattle naturally parasitized by Eurytrema spp. Concordia-SC region, correlating to the number of parasites present in the pancreas. A total of 119 pancreas, feces and blood were collected and identified from cattle of varying slaughter age, sex, and race. The animals were classified as parasitized and non parasitized for Eurytrema coelomaticum, were found 71 positive and 48 negative, making a prevalence of 59.06%. The average specimen per infected pancreas was 628 parasites, ranging from 6 to 3,829. With the feces, the gelatin tube digestion test was performed, resulting in 37 positive and 34 negative for the test in the group parasitized by Eurytrema spp and in the non parasitized group all samples were positive to the test. Similar results were obtained with the radiographic film digestion test, and among the parasitized animals there were 35 positive and 36 negative for the test and in all others were positive for the presence of trypsin. The biochemical analysis of amylase was also performed, which in the parasitized animals presented an average of 88.81 ± 48.91 IU / L. While the non-parasitized had an average of 69.38 ± 30.30 IU / L. When the variables are correlated, it is clear that the tube gelatin pancreatic function test has a significant negative correlation (P <0.01) when compared to the parasitic load on the pancreas, as well as the radiographic film digestion (P <0; 01). There is also a significant correlation between the two pancreatic function tests: gelatin and X-ray. When the serum amylase test was analyzed, it only showed a significant correlation (P <0.05) with the positive or negative group to the parasite, but without correlation with the parasite. the parasitic load. Finally, pancreatic function tests were correlated (P <0.01) with the group of parasites or not, while amylase was significantly higher only in the group parasitized. The work is in progress and lipase dosage, endocrine pancreas evaluation, and fecal starch research are also being performed.
