Influence of a newly-synthesised 5-oxo-1,2,4-triazyne derivative on antioxidant indices of blood and performance of turkey hens
The aim of the study was to evaluate the influence of a newly-synthesised 5-oxo-1,2,4-triazyne derivative on the antioxidant status and performance of turkey hens. The experiment was conducted on six-week old Big-6 turkey hens, divided equally into four groups (60 birds/group). The treatments were: T0 – control (no triazyne supplement) and T15, T30, T45: 5-oxo-1,2,4-triazyne supplementation at 15, 30 and 45 μg/kg BW/day, respectively. The additive was administered over a period of eight weeks. A two-week break with no triazyne supplementation was given in the middle of that period. The performance indices were body weight, feed conversion ratio and the Index of Rearing Effectiveness (WEO). The antioxidant parameters were superoxide dismutase, glutathione peroxidase and catalase activity in erythrocytes and copper, iron and zinc concentrations in plasma. None of these measurements were affected by any of the supplementation treatments. However, after four weeks the supplementation of the 5-oxo-1,2,4-triazyne derivative caused a significant increase in superoxide dismutase activity in the erythrocytes of the hens, and after 10 weeks, only at the highest dose of supplementation. After four weeks of supplementation, the group that received the highest dose of the additive showed an increase in total antioxidant potential (FRAP) in the plasma as well as in its components, i.e. uric acid and vitamin C. After 10 weeks of supplementation a decrease was recorded in the FRAP value, as well as in uric acid, ascorbic acid and Cu concentrations in plasma. The observed growth of enzymatic and non-enzymatic antioxidants may indicate a mobilization of the antioxidant defence system. However, at the end of experiment, the significant decrease in the plasma concentration of the non-enzymatic antioxidants suggests that the body reserves were depleted.Keywords: Amidrazone derivative, antioxidant status, FRAP, Index of rearing effectivenes
Content of selected metals in forest fruits depending on the harvest site
Oznaczono zawarto艣膰 Pb, Cd, Cu, Zn, Fe i Mn w pr贸bkach owoc贸w le艣nych: bor贸wki czarnej, maliny w艂a艣ciwej i poziomki pospolitej, pozyskanych w woj. lubelskim, na obszarach uznanych za potencjalnie wolne od zanieczyszcze艅 (Skierbieszowski Park Krajobrazowy) i na terenach potencjalnie zanieczyszczonych (Cementownia Rejowiec S.A.). Analizowane owoce pochodz膮ce ze stanowisk bardziej nara偶onych na emisj臋 zanieczyszcze艅 charakteryzowa艂y si臋 wy偶sz膮 zawarto艣ci膮 o艂owiu (z wyj. maliny w艂a艣ciwej) oraz pozosta艂ych metali, ni偶 badane surowce z terenu Gminy Kra艣niczyn. Spo艣r贸d analizowanych owoc贸w najni偶sz膮 zawarto艣膰 Pb, Zn, Fe, Mn odznacza艂a si臋 bor贸wka czarna, natomiast najwi臋ksz膮 zawarto艣ci膮 Pb, Zn i Mn charakteryzowa艂a si臋 poziomka pospolita. Zawarto艣膰 kadmu w analizowanych surowcach ro艣linnych by艂a wysoka.Contents of selected metals (Pb, Cd, Cu, Zn, Fe, Mn) were determined in samples of forest fruits: blueberry, raspberry and wild strawberry harvested in Lublin region from areas considered as potentially not exposed to pollution (Skierbiesz贸w Landscape Park) and potentially polluted areas (Cement Factory Rejowiec S.A.). Analyzed fruits originating from stands more exposed to pollution were characterized by higher lead (except from raspberry) as well as other metals contents than those from Krasiczyn commune. Among studied fruits, blueberry was distinguished by the lowest contents of Pb, Zn, Fe, Mn, wild strawberry contained the highest levels of Pb, Zn and Mn. Cadmium content in analyzed plant materials was high
Influence of Synthesized 5-Oxo-l,2,4-Triazyne Derivative on Some Immunological and Hematological Indices of Turkey
Influence of habitat conditions on macroelements and trace elements in selected fruits grown in the Lublin region
Oznaczono zawarto艣膰 makroelement贸w oraz pierwiastk贸w 艣ladowych w owocach porzeczki czarnej, porzeczki czerwonej, maliny, 艣liwki w臋gierki i winogrona bia艂ego. Materia艂 do bada艅 pobrano w wojew贸dztwie lubelskim na terenach potencjalnie nara偶onych i nienara偶onych na ekspozycj臋 zanieczyszcze艅 (ogrody dzia艂kowe w Lublinie oraz ogrody dzia艂kowe na wsi). W badanych owocach stwierdzono bardzo wysok膮 zawarto艣膰 kadmu - od 0,192 mg-kg-1 do 0,545 mg-kg-1 艣wie偶ej masy, co wielokrotnie przekracza艂o warto艣膰 dopuszczaln膮 0,03 mg-kg-1 dla owoc贸w jagodowych oraz 0,02 mg kg-1 dla owoc贸w pestkowych. Zawarto艣膰 badanych makroelement贸w (Na, K, Ca, Mg) i pozosta艂ych pierwiastk贸w 艣ladowych (Pb, Cu, Zn, Fe, Mn) by艂a dosy膰 niska i nie stanowi艂a zagro偶enia dla zdrowia cz艂owieka.The content of some macroelements as well as trace elements in blackcurrant, redcurrant, raspberry, sweet prune and white grape fruits collected in Lublin region was determined. Samples for determinations were taken from areas potentially exposed and unexposed to pollution (gardens in the town of Lublin and in the countryside). The analysed fruits were characterised by a very high Cd content, ranging from 0.192 mg-kg-1 to 0.545 mg-kg-1 of fresh mass. Such concentrations considerably exceeded the permissible level of 0.03 mg-kg-1 for berries and 0.02 mg-kg-1 for drupes. The content of the remaining macroelements (Na, K, Ca, Mg) and trace elements (Pb, Cu, Zn, Fe, Mn) was low enough and did not create danger to human health
Contents of tannins and oxalic acid in the selected forest fruits depending on the harvest site
Oznaczono zawarto艣膰 garbnik贸w oraz kwasu szczawiowego w owocach: bor贸wki
czarnej, maliny w艂a艣ciwej oraz poziomki pospolitej, pozyskanych z teren贸w
potencjalnie wolnych od zanieczyszcze艅 (Gmina Kra艣niczyn) oraz z miejsc bardziej
nara偶onych na emisj臋 zanieczyszcze艅 (Rejowiec Fabryczny). Zawarto艣膰 garbnik贸w
w owocach poziomki pospolitej oraz koncentracja kwasu szczawiowego w owocach
bor贸wki czarnej, pochodz膮cych z okolic potencjalnie nie nara偶onych na ekspozycj臋
zanieczyszcze艅 by艂a wy偶sza, ni偶 w surowcach pozyskanych z okolic Rejowca Fabrycznego.
艢rednie zawarto艣ci garbnik贸w oraz kwasu szczawiowego w analizowanych
owocach le艣nych by艂y niskie.Contents of anti-nutritional components (tannins and oxalic acid) were determined in samples of forest fruits: blueberry, raspberry and wild strawberry harvested in Lublin region from areas considered as potentially not exposed to pollution (Skierbiesz贸w Landscape Park) and potentially polluted areas (Cement Factory Rejowiec S.A.). Study revealed that blueberry and raspberry fruits collected on potentially polluted area were characterized by higher tannins contents than those harvested on potentially not polluted area. Oxalic acid level in studied material indicated its significantly higher concentration in wild strawberry fruits collected both from not exposed and polluted areas as compared to raspberry and blueberry. Tannins and oxalic acid contents in analyzed berries may be accepted as low and safe for human's health
