Wpływ toksykozy zearalenonowej na wyniki badania morfologicznego i biochemicznego krwi dzików

The aim of this study was to assess the effect of zearalenones (ZEA) on the complete blood cell count and serum chemistry analysis in wild boars (Sus scrofa). At the beginning of the study, blood was collected from 24 wild boars. The following parameters were evaluated: the leukocyte and red blood cell counts, haemoglobin concentration, MCV, MCH, MCHC, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, urea, creatinine, total protein, albumin, total bilirubin, calcium, inorganic phosphorus and magnesium. The wild boars were then divided into three study groups containing six sows and two boars each. The study was carried out over the course of three years. Group I received feed for fattening boars and corn containing 50 µg of ZEA. Group II received the same feed as group I, with the addition of a pure form of ZEA, supplemented at a dose of 150 µg/kg/day for 7 days every 2 months. In the course of the study, the animals in this group received a total of nine 7-day administrations of this toxin. Group III was the control group. A complete blood cell count and serum biochemical analysis were performed once again at the end of the study, and, in group I, three months after commencing the study. The CBC indices measured at the end of the study did not differ significantly among the three groups. There were significant differences in the AST, ALT and total bilirubin concentrations measured at the end of the study between group I and the remaining two groups. The high AST, ALT and total bilirubin concentrations suggest that a three-year-long ingestion of mouldy feed significantly affects the liver function, but does not cause clinical signs of poisoning.
