Farm animals are at risk of exposure to zearalenone (ZEA) in feedstuffs, which may lead to aberrations in their reproductive development, thereby adversely affecting production outcomes. The objective of this study was to determine the effect of long-term (48 days), per os administration of low ZEA doses (50% [20 μg ZEA/kg body weight (bw)] and 100% [40 μg ZEA/kg bw] NOAEL values) on anatomopathological...
The objective of this study was to examine the clinical significance of selected indicators of immune response (IL-lß, 1L-4, IL-6. SAA, and Hp) in short-term combined intoxication exposure of pigs to low doses of deoxynivalenol, T-2 toxin, and zearalenone present in naturally contaminated feedstuffs during grain growth. Statistically significant differences were not noted after 14 d of feeding diets...
The aim of the study was to evaluate the influence of low dose (LOEL - lowest observed effect level) of zearalenone (200 μg/kg b.w.), applied per os for 7 days (short-term intoxication), on sexual behavior, concentration of the examined xenobiotic and its metabolite and selected estrogens in sexually immature gilts: ovariohysterectomised (group Dl) and intact (group D2) animals. Clinical signs of...
Weather anomalies are the cause of the more and more frequent occurrence of the rezorcycyklic acid derivatives - zearalenone - in the fodders of the animal origin. This mycotoxine induces in the organism of gilts an oestrus-like condition. According to the latest reports the zearalenone derivatives were found in the human food-stuffs in the retail market. It was considered important to assay the concentration...
Mikotoksykozę zearalenonową świń klinicznie charakteryzuje obrzęk i zaczerwienienie sromu, zaburzenia w płodności i splayleg prosiąt. Podczas sekcji stwierdza się spadek masy jajników, powiększenie macicy i gruczołu mlekowego. Celem pracy było określenie wpływu jednokrotnego podania per os niskich dawek ZEA (1,0 i 1,5 mg ZEA. kg⁻¹ paszy) na aktywność AST, ALT i ALP u świń. Wzrost aktywności enzymów...
Zbadano współdziałanie monoacylogliceroli i karboksylanów sodu, w otrzymanych modyfikowanych emulgatorach acyloglicerolowych, w celu określenia wpływu składu emulgatora na jego właściwości międzyfazowe na granicy olej/woda. Określono wpływ długości łańcucha węglowodorowego monoacylogliceroli i karboksylanów na adsorpcję i micelizację. Na podstawie wyznaczonych krzywych zależności napięcia międzyfazowego...
