The intensity of reproduction of the live-stock of pigs largely depends on environmental factors, in particular fluctuations in indoor temperature, which is often seasonal. It was found out the fact that in the summer with a long rise in temperature it is worsened the quality of sperm in boars, which is accompanied by a decrease in the fertility of sperm, and in multiplicity and large foetus fertility of sows. The aim of the study was to determine the influence of antioxidant vitamins on the prooxidant-antioxidant homeostasis in  blood of boars under the conditions of heat stress. In the study it was used the adult boars of the Large White breed. The duration of the experiment was 120 days, including: preparatory one is 30 days, basic one is 60 days (feeding vitamin A, vitamin E, ascorbic acid) and final one is 30 days. In the main period of the experiment, the diet of animals in the control group remained unchanged, and it was for  two experimental ones with the addition of vitamin A, vitamin E and ascorbic acid. The level of biologically active components in the diet of the experimental groups was higher by 10 % and 20 % compared with the control group. In the received blood samples it has been  determined  the state of prooxidant-antioxidant state. It has been determined that housing boars in conditions of increased temperature is accompanied by the acceleration of peroxidation processes and the depletion of the antioxidant defense system in  blood. The introduction of a vitamin supplement in the feed mixture to boars significantly changes the state of prooxidant-antioxidant homeostasis in this tissue depending on the amount of additionally fed vitamins with antioxidant action. The addition of these biologically active substances by 10 % above the norm after 60 days of feeding increases the content of vitamin A (P < 0.05), vitamin E (P < 0.05), reduced glutathione and slows down the processes of peroxidation – reducing the concentration of diene conjugates (P < 0.01) and TBA-active complexes. Feeding vitamins with antioxidant action in the feed mixture is 20 % more than the norm for boars, compared with the control group, after a month of the use, inhibits peroxidation processes. Two months of using  these compounds probably reduced the number of diene conjugates (P < 0.01) and TBA-active complexes. It is accompanied by an increase in the content of low molecular weight antioxidants – vitamin A (P < 0.01), vitamin E (P < 0.05) and ascorbic acid, the level of which is maintained for at least a month after their use.

The peculiarities of formation of prooxidant-antioxidant homeostasis (PAG) in boars of different types of higher nervous activity have been studied. Using motor-nutritional techniques, it has been opposed adult boars of the Large White breed aged 24–36 months according to the main types of higher nervous activity (HNA). Four groups of 3 heads each were formed. The first group includes animals of a strong balanced lively (mobile) type; group II includes a strong balanced calm (inert) type; group III includes a strong unbalanced (unrestrained) type; group IV includes a weak type of higher nervous activity. Sperm was received from boars manually, taking into account the total time of ejaculation, dividing the ejaculate into 4 fractions – F1 – the first, F2 – the second, F3 – the third, F4 – the fourth. PAGs in blood and ejaculates of boars were evaluated by the intensity of peroxidation processes (xanthine oxidase, diene conjugates, TBA-active compounds) and antioxidant defense systems (superoxide dismutase, catalase, reduced glutathione, ascorbic acid, vitamin A and vitamin E). Sperm contained higher amounts of diene conjugates and TBA-active complexes (P < 0.05) compared to blood. The second tissue relative to the first one is characterized by a higher level of antioxidant defense: catalase activity, concentration of ascorbic acid, vitamin A and vitamin E. The process of PAG formation in the tissues of boars depends on the type of higher nervous activity (HNA). Thus, in individuals of a strong balanced lively and calm type, the course of peroxidation processes is somewhat slower because of a lower concentration of diene conjugates and TBA-active complexes. It was determined the fact that in blood and sperm of boars of strong unbalanced and weak types of HNA the course of peroxidation is more intense, the antioxidant defense system is at a lower level that is connected with less superoxide dismutase activity (P < 0.05), concentration of ascorbic acid (P < 0.001), vitamin A (P < 0.01–0.001), and vitamin E (P < 0.001). In the second and third fractions of ejaculate of boars, the PAG is shifted in the direction of probable acceleration of peroxidation processes, especially in strong unbalanced and weak types of HNA because of a higher concentration of diene conjugates, dehydroascorbic acid. Animals of a strong balanced lively and calm types of HNA are characterized by a higher level of antioxidant defence – catalase activity, superoxide dismutase, reduced glutathione, ascorbic acid and vitamin E. In the first and fourth fractions of ejaculate, peroxidation processes are slower and there is no superoxide dismutase activity and the amount of vitamin A and vitamin E.

The electrochemical analysis of cytochrome Р450 3А4 catalytic activity has shown that vitamins C, A and Е influence on electron transfer and Fe3+/Fe2+ reduction process of cytochrome Р450 3А4. These data allow to assume possibility of cross effects and interference of vitamins-antioxidants with drugs metabolised by cytochrome Р450 3А4, at carrying out of complex therapy. This class of vitamins shows antioxidant properties that lead to increase of the cathodic current corresponding to heme reduction of this functionally significant haemoprotein. Ascorbic acid of 0.028-0.56 mM concentration stimulates cathodic peak (an electrochemical signal) of cytochrome Р450 3А4. At the presence of diclofenac (Voltaren) - a typical substrate of cytochrome Р450 3А4 - the increase growth of a catalytic current testifying to an electrocatalysis and stimulating action of ascorbic acid is observed. In the presence of vitamins A and Е also is registered dose-dependent (in a range of 10-100 M) increase in a catalytic current of cytochrome Р450 3А4: the maximum increase corresponds to 229 ± 20% for 100 M of vitamin A, and 162±10% for 100 M of vitamin E. Vitamin E in the presence of P450’s inhibitor itraconazole doesn't give essential increase in a reductive current, unlike retinol (vitamin A). This effect can manifest substrate properties of tocopherol (vitamin E). The electrochemical approach for the analysis of catalytic activity of cytochrome Р450 3А4 and studies of influence of biologically active compounds on an electrocatalysis is the sensitive and effective sensor approach, allowing to use low concentration of protein on an electrode (till 10-15 mol/electrode), to carry out the analysis without participation of protein redox partners, and to reveal drug-drug or drug-vitamins interaction in pre-clinical experiments.

The results of research on the features of cyclic lability of homeostasis in gilts are highlighted. In the experiments it has been used gilts of the Red White belted breed of meat pigs at different phases of the reproductive cycle: luteal phase, estrus, on the 15th, 20th, 30th, 60th, 90th, 104th, 113th day of pregnancy and in 12 hours after farrowing. The dynamics of the content of thyroid and steroid hormones, as well as the peculiarities of the formation of prooxidant-antioxidant homeostasis were determined in blood serum. It was found out that the amount of steroid hormones in blood of gilts is labile and is determined by the physiological state, namely the onset of estrus, relative to the luteal phase, it is increased the level of thyroxine (30.0 %), triiodothyronine (26.3 %), estradiol-17 β (by 22.8 %, P < 0.01) testosterone (15.2 %), as well as a decrease in progesterone (by 37.2 %). Such changes are accompanied by the acceleration of peroxidation processes, xanthine oxidase activity increases, it is increased the content of diene conjugates (P < 0.05) and TBA-active compounds. This is accompanied by a probable increase in the level of antioxidant protection – the activity of superoxide dismutase (P < 0.05), vitamin A (P < 0.05) and vitamin E (P < 0.05). During two months of pregnancy, the concentration of thyroxine (P < 0.05), triiodothyronine, progesterone (P < 0.01), testosterone (P < 0.05) and estradiol-17β increases. Such metabolic shifts cause changes in the state of prooxidant-antioxidant homeostasis in the direction of reducing the intensity of peroxidation processes. In gilts before farrow there is a decrease in thyrocoxin, triiodothyronine and progesterone. The intensification of peroxidation was found: the increase in SOD activity (P < 0.05), the dehydroascorbic acid content (P < 0.05), diene conjugates and TBA-active complexes, as well as the decrease in the concentration of reduced glutathione and vitamin A (P < 0.05) and vitamin E (P < 0.05). In blood of sows after farrowing, the concentration of thyroxine increases on 1.3 times, triiodothyronine – on 2.7 times, and progesterone and estradiol-17β decreases on 1.8 and 8.7 times, respectively. It was revealed that the intensity of lipid peroxidation processes decreased: DC content by 16.3 % and TBA-active complexes by 13.3%. It was determined that the concentration of ascorbic acid decreased by 32.8 % and vitamin E – 18.9 %.

The use of chelated compounds of trace elements as an alternative to mineral salts can increase their conversion, reduce the content in feed and prevent environmental pollution. However, it remains relevant to study the effect of these substances on the reproductive capacity of pigs. The aim of the study was to determine the effect of prooxidant-antioxidant homeostasis (PAH) on the functional activity of sperm of boars in the correction of mineral nutrition. The study used adult boars of the Large White breed. The duration of the experiment was 120 days, including: preparatory - 30, basic - 60 (feeding lactates of Zinc, Selenium, Copper and Iron) and final - 30 days. In the main period of the experiment, the diet of animals in the control group remained unchanged, and two experimental were with the addition of lactates Zinc, Selenium, Copper and Iron. The level of biologically active components in the diet of the experimental groups was higher by 10% and 20% compared with the control group. In the obtained blood samples it was determined the state of PAG. The functional activity of sperm in stored spermatozoa at 170C after 3 hours of incubation was determined by their activity and survival by testing for heat resistance, heat stress resistance, the number of anomalies and the integrity of acrosomes. It was found that the introduction of lactates of Zinc, Selenium, Copper and Iron in the feed mixture to boars significantly changes the state of PAG in blood depending on the number of additionally fed lactates of trace elements. The addition of these biologically active substances by 10% above the norm after 60 days of feeding helps to preserve the content of antioxidant vitamins, reduced glutathione, stimulates the functional activity of superoxide dismutase by 50% and catalase by 23.6% and is accompanied by a slight decrease in peroxidation processes. conjugates and TBC-active complexes. The addition of lactates of micronutrients to the feed mixture is by 20% more than norma for boars, compared with the control group, after 30 days of use stimulates peroxidation, accompanied by intensive use of non-enzymatic - vitamin A (p <0,05-0,01) and activation of enzymatic antioxidants - superoxide dismutase (p <0.05-0.01) and catalase, which lasts for 90 days. The viability of sperm is significantly correlated with the number of additionally fed lactates of trace elements. The addition of these biologically active substances by 10% more than normal after 60 days of feeding helps to increase the functional activity of sperm for 3 hours at a temperature of 170C storage, heat resistance (p <0.05), heat stress resistance, increases their ability to fertilize. The addition of lactates of micronutrients in the feed mixture is by 20% more than the norm for boars in comparison with the control group after two months of feeding increases the number of pathological forms of sperm (p <0,005), acrosome damage (p <0,05), reduces heat resistance and heat stress resistance of sperm <0.05), which reduces their fertility. It was found the fact that the processes of peroxidation in blood of boars are significantly interrelated with the functional activity of sperm in stored spermatozoa. The content of primary and secondary peroxidation products significantly correlates with the fertilizing ability of sperm in the range of r = 0.95… 0.99. The activity of superoxide dismutase and catalase are significantly interrelated with the fertilizing ability of sperm: in animals of the second group, the correlation coefficients were respectively r = 0.98 and r = 0.97, the third - r = 0.12 and r = 0.96, the first - r = - 0.58 and r = 0.80.

An experiment on Cobb-500 male broilers was conducted to evaluate the effects of vitamin E (alfa-tocopherol-acetate), vitamin A (retinol), and their combination on broiler performance and serum concentrations of triiodothyronine (T3), thyroxine (T4), adrenocorticotropine hormone (ACTH) and some metabolite and mineral concentrations in broilers reared under heat stress (32&deg;C). One day-old 120 broilers were randomly assigned to 4 treatment groups, 3 replications of 10 birds each. The birds were fed either a control diet or a control diet supplemented with either vitamin A (15 000 IU retinol/kg diet), vitamin E (250 mg alfa-tocopherol-acetate/kg diet), or a combination of vitamin A and E (15 000 IU retinol plus 250 mg of alfa-tocopherol-acetate/kg diet). Considered separately or as a combination, supplemental vitamin A and vitamin E increased feed intake (P&nbsp;= 0.01) and live weight gain (P&nbsp;= 0.03). However, feed efficiency remained similar in all treatments (P= 0.18). Serum T3&nbsp;and T4&nbsp;concentrations were also higher (P&nbsp;&le; 0.001) with vitamin A, vitamin E, and vitamin A plus vitamin E groups than those of the control. However, ACTH concentration in serum was lower (P&nbsp;&le; 0.001) in supplemental dietary vitamin groups compared with control. Serum glucose, uric acid, triglyceride, and cholesterol concentrations decreased (P&nbsp;&le; 0.001) while protein and albumin concentrations increased (P&nbsp;&le; 0.001) when both dietary vitamin E and vitamin A were supplemented. Serum activities of serum glutamic oxalate transaminase (SGOT) and serum glutamic pyruvate transaminase (SGPT) were not influenced by dietary vitamin E, vitamin A nor by a combination of vitamin A and vitamin E (P&nbsp;&gt; 0.72). However, serum activity of alkaline phosphatase (AP) increased (P&nbsp;&le; 0.001) with supplemental dietary vitamin E, vitamin A, or a combination of vitamin A and vitamin E. In addition, supplemental dietary vitamin E and vitamin A resulted in an increase in serum concentrations of both Ca and P (P &le; 0.001). In general, when a significant effect was found for a parameter, the magnitude of responses to vitamin supplements was greatest with the combination of vitamin A and vitamin E, rather than that of each vitamin supplement separately. The results of the present study show that supplementing a combination of dietary vitamin E and vitamin A offers a good management practice to reduce heat stress-related decreases in broiler performance. &nbsp;

SummaryInterest in the use of antioxidants for the treatment of human disease, and in the role of dietary antioxidants in the prevention of disease development, has been sustained for at least two decades. Several anti-oxidant protective mechanisms exist and constitute a primary defensive system including enzymatic defences (glutathione peroxidase and superoxide dismutase, which depend on the presence of ions such as selenium, zinc, copper, and manganese) and naturally occurring vita-mins such as vitamin E, vitamin A, beta-carotene, and vitamin C. The most important natural antioxidants are vitamin E (in the form of α-, β-, γ-, and δ-tocopherols), beta-carotene, vitamin C and selenium (fundamental constituent of glutathione-peroxidase, i.e., an enzyme with antioxidant function). The first two are lipophilic substances whilst ascorbic acid is hydrophilic. Each antioxidant has a different important mechanism of action since oxidative damage can be caused by lipid- or water-soluble molecules. Lipid-soluble antioxidants are likely to be very important in preventing the peroxidation of low-density lipo-proteins (LDL) and this action could be paramount in the prevention of atherosclerosis. On the other hand, water-soluble antioxidants could be useful where a water-soluble oxidative stress occurs (e.g., inflammation). As lipophilic molecules, vitamin E and beta-carotene are incorporated into the LDL particle. Vitamin E is the main lipid-soluble chain-breaking antioxidant in plasma and tissues and converts the peroxyl-free radical to hydroperoxide, a less reactive radical. It acts as a first-line anti-oxidative defence of LDL particles, protecting unsatu-rated fatty acids from peroxidation. Beta-carotene is a carotenoid (precursor of vitamin A, pro-vitamin) that acts as scavenger of oxidising radicals such as singlet oxygen and is a second-line antioxidative defence of LDL cholesterol. Vitamin C (ascorbic acid) can react with singlet oxygen, superoxide, hydroxyl radicals, and is the first line of antioxi-dative defence in water-soluble compartments. In addition, it plays an important role in regenerating reduced -tocopherol.

The development of stomatitis is characterized by the appearance of oxidative stress, which is marked by an increase in the intensity of peroxide lipid oxidation processes, resulting in metabolic disturbance in oral mucosa. As a result, toxic substances accumulate and endogenic toxicity develops. Thus, correction of pathological processes in the oral mucosa with antioxidant medication enables to optimize the intensity of inflammation, shorten the period of catabolic phase and accelerate the regeneration. Extract of Geranium palustre herb as a dental film was used to reduce the intensity of processes of lipid peroxidation and endogenous intoxication. This treatment method enables to release an active substance from the drug locally and to provide optimal therapeutic effect. The efficacy of the experimental medication was studied in the dynamics of experimental ulcerative stomatitis development in rabbits. The experimental model of ulcerative stomatitis in animals was induced with a burn method. For the experiment, the animals were divided into 2 groups: control group, where treatment was not performed, and experimental group, where animals were treated by applying a dental film with Geranium palustre extract. The monitoring was conducted on the 3rd, 5th, 7th and 10th days of the experiment, which are key stages of healing. During these periods, blood was taken under anesthesia from the auricular vein of each experimental animal. Dynamics of prooxidant processes was detected by the level of lipid hydroperoxides and malondialdehyde, and the level of endogenic toxicity by the content of middle molecules. Statistic processing of the obtained results of investigation was performed using personal computer with installed proper software package StatSoft Statistica 10. Reliable difference was considered р<0.05. It has been shown that extract of Geranium palustre herb, as a dental film, has antioxidant properties, which are effectively reducing the intensity of lipid peroxidation processes. It should be mentioned that the content of lipid hydroperoxides and final product of lipid peroxidation processes – malondialdehyde – in experimental animals’ blood was statistically lower in all periods of investigation than in control group, where treatment was not performed. The obtained results show that higher inhibiting effect of experimental medication is marked during the final stage of lipid peroxide oxidation than during the initial stage. As the result showed, the development of endogenic toxicity was observed in both groups and the highest indices were recorded at the peak of the inflammatory process on the third day of the experiment. Dynamics of middle molecules content shows that application of Geranium palustre extract, as a dental film, decreases this index during all investigated periods and reduces intoxication level in experimental animals. Thus, application of dental film in stomatitis treatment enables to release medication directly into the damaged area, which significantly increases therapeutic effect of biologically active substances of Geranium palustre phytocomplex, and rapid absorption of the film in the oral cavity provides easy use. Considering efficacy, non-toxicity and availability of the investigated medication, the expediency of its application in dental practice for the treatment of stomatitis and other inflammatory diseases of the oral mucosa may be considered.
