The experiment was conducted to determine the effect of adequate zinc level supplementation (inorganic versus organic form) on the innate immune response of kids. The count of white blood cells, leukocyte differential count, phagocytic activity, and phagocytic index (as markers of the immune functions) were determined. Phagocyticic activity was not significantly higher in the inorganic-zinc-treated group in comparison to the control (64.7±8.91 vs 61.2 ± 9.15 %). The production of reactive oxygen species (ROS) by goat's blood neutrophils was detected by luminol-enhanced chemiluminescence (CL). CL was performed to determine integral CL, peak CL, and peak-time after addition of calcium ionophore A23187 (Cal-I), opsonised zymosan (OZP), and phorbol- 12-myristate-13-acetate (PMA). A significant ROS increase reflected in peak CL (P≤0.05) was found in the lactate-Zn-treated group when Ca-I was used as activator. In the same group there was a significant integral CL increase (P≤0.05) when we used Ca-I as activator. Others parameters showed no significant changes.

Standard DJ feed mixture for laying hens (ISA Brown) was supplemented with organic or inorganic forms of selenium and zinc. The organic forms consisted Saccharomyces cerevisiae yeast enriched with Se (Y-Se) and Zn (Y-Zn). The inorganic forms were sodium selenite (Na-Se) and zinc oxide (ZnO). The concentrations of elements in the experimental feed were (mg·kg-1): selenium 1.414 (Y-Se) and 1.393 (Na-Se); zinc 79.3 (Y-Zn) and 78.9 (ZnO). After 6 days of feeding treatment, for the next 5 days there were collected droppings and eggs to determine Se and Zn concentrations with the use of ICP method. It was stated that in hens availability of elements (as apparent absorption) was respectively (%): Y-Se 63.65, Y-Zn 38.5, Na-Se 61.12 and ZnO 35.41. In eggs content of Y-Se hens the increase of Se was proved if compared to Na-Se eggs (p<0.05).

The paper presents results of research concerning an assessment of bioaccumulation of copper, manganese and zinc in Lohmann Brown layer hens (5 groups of 12 hens in each). Using ICP-MS method the concentration of these elements was determined in the content and shell of eggs, whole blood and in feathers of hens. Feeding was based on all-mash feed mixture J-297 type with a content of Cu – 21.8, Fe – 200.8, Mn 140.5 mg⋅kg-1, but in particular groups the contribution of organic and inorganic forms of these 3 microelements was different. Content of Zn in the mixture was 86 mg⋅kg-1 (zinc oxide). Microelements in the amounts of: Cu – 10, Fe – 40 and Mn – 80 mg⋅kg-1 were separately introduced to the control and to the test mixtures by using special premixes. In the control version, inorganic forms of these elements were used in a premix (copper sulfate, iron sulfate and manganese oxide), while in the experimental version they appeared in the organic form, i.e. Saccharomyces cerevisiae yeasts enriched with the three elements. In the experimental mixtures the contribution of organic forms of microelements was for Cu – 47, Fe – 20 and Mn – 58%. Content of the premix in a mixture was 0.5%. Yeasts contained: Fe – 33.9, Mn – 35.4, and Cu – 22.7 mg⋅kg-1 d.m. Content of yeasts in the mixtures did not exceed 0.4%. Application of organic forms of copper caused a significant increase in copper concentration in the egg content and shell, in blood and in feathers in the group receiving organic- Cu, which proves better availability of copper from organic forms compared to copper sulfate. Introduction of organic forms of iron and manganese to feed did not cause any significant changes in the content of these metals in eggs, blood and feathers of hens, except the organic-Mn group (the level of Mn in feathers was significantly higher in feathers compared to the control group). Organic forms of copper, manganese and iron did not result in any interactions with respect to Zn although an antagonistic influence of Cu (organic- Cu group) and synergistic of Mn (organic-Mn group) in the egg content was observed.

Many selenoorganic compounds play an important role in biochemical processes and act as antioxidants, enzyme inhibitors or drugs. The effects of a new selenocompound — bis(2-aminophenyl)-diselenide on oxidative/nitrative changes in human plasma proteins induced by peroxynitrite (ONOO−) were studied in vitro and compared with the those of ebselen, a well-known antioxidant. We also studied the role of the tested selenocompounds in peroxynitrite-induced plasma lipid peroxidation. Exposure of the plasma to peroxynitrite (0.1 mM) resulted in an increase in the level of carbonyl groups and nitrotyrosine residues in plasma proteins (estimated using the ELISA method and Western blot analysis). In the presence of different concentrations (0.025–0.1 mM) of the tested selenocompounds, 0.1 mM peroxynitrite caused a distinct decrease in the level of carbonyl group formation and tyrosine nitration in plasma proteins. Moreover, these selenocompounds also inhibited plasma lipid peroxidation induced by ONOO−1 (0.1 mM). The obtained results indicate that in vitro bis(2-aminophenyl)-diselenide and ebselen have very similar protective effects against peroxynitrite-induced oxidative/nitrative damage to human plasma proteins and lipids.
