The aim of this study was to investigate the effect of Bendamin on the antioxidant status of rats in experimental doxorubicin-induced cardiomyopathy. The studies were performed on white sexually mature young male of Vistar line rats weighing 180–200 g, which were kept on a standard diet of the Institute Vivarium of the State Research Institute of Veterinary Drugs and Feed Additives. Animals were divided into 3 groups of 6 animals in each: control group – intact animals; experimental group R1, in which animals were simulated with doxorubicin-induced cardiomyopathy by intraperitoneal administration of doxorubicin at a dose of 2.5 mg/kg 3 times a week for two weeks; experimental group R2, in which animals were injected with the drug “Bendamin” at a dose of 20 mg/kg after injection of doxorubicin. The data obtained indicate that the introduction into the experimental animals of the experimental group of doxorubicin is accompanied by intensification in the myocardium of the processes of free radical oxidation. The increase in diene conjugates was found to be 32.7% and TBK-active products increased by 37.6% compared to the control group of rats. Doxorubicin was also found to cause inhibition of the glutathione system of the animal's antioxidant protection after administration to rats. After administration of the drug “Bendamin”, rats of the second experimental group were suppressed with lipid peroxidation under the conditions of doxorubicin intoxication. In the rats of the second experimental group, the level of intermediates and end products is likely to decrease, so in the rat myocardial homogenate the level of diene conjugates decreased by 16.8% and the level of TBA-active products by 20.8% compared to the first experimental group. who had clinical signs of cardiomyopathy caused by doxorubicin administration. The use of the drug “Bendamin” in rats of the second experimental group contributed to the enhancement of the enzymatic and non-enzymatic element of the antioxidant system, protecting the structural and functional integrity of cell bioembranes. The results of the studies enrich the pharmacological characteristics of the drug “Bendamin”, indicate its sufficiently clear protective effect on the myocardium in experimental doxorubicin cardiomyopathy and is a convincing proof of the feasibility of the drug in veterinary practice.

Radical Oxidation

In fact, Free radical oxidation is one of the required factors of homeostasis as far as the active forms of oxygen, which have unpaired electron, perform useful functions, they are necessary intermediaries of numerous processes of normal cells’ functioning such as biosynthesis of prostaglandins and leukotriene as well as other biologically active substances. Also, they take part in pathological processes such as: inflammation, fever and others. Free radical oxidation is the process of direct oxygen transferring to the substrate forming peroxide, ketones, aldehydes, etc. Some amino acids, proteins, water and carbohydrates prone to the processes of peroxidation, but crucial place is granted to lipids at the expanse of fatty acids which are included to their composition. The article highlights the information concerning the analysis of the state of antioxidant system of hens in the process of feeding them with subtoxic doses of fungicide of Derosal (BAYER, Germany) (0.1 LD50 for a fowl, 900 mg/kg of the body mass) which active ingredient is benzimidazole carbamate (carbendazim, BMC). It presents the changes of these indicators in the process of using pharmacological and natural antioxidants. The analysis has figured out that giving Derosal to the hens without corrections (II group) has been followed with the activation of the process of lipids’ peroxidation (POL) in the blood plasma, that is followed with the increase of concentration of primary and secondary lipoperoxidation products – diene conjugates (DC) and TBA-active products on the average up to 21.0–25.0 %, catalase activity – up to 38.5 % and decrease of superoxide dismutase activity (SOD) up to 21.8 % and АОА – up to 17.8 %, that shows the adverse effects of pesticides on the system of antioxidant protection of the organism. In the fowls’ groups III, IV and V the adding of antioxidant E-selenium, ascorbic acid and thermally untreated buckwheat seeds as the source of  quercetins and anthocyanins has led to the induction of antioxidant resources that is shown by the decrease in comparison with the control of content of diene conjugates, malonic dialdehyde and catalase (in average up to 13.6–33.6–18.0 % accordingly) and compensatory strengthening of superoxide dismutase activity and general activity of antioxidant (АОА) on the average up to 44.9–72.1–76.5 % and 15.3–13.4–21.7 % accordingly. In comparison with group II the activity of catalase has been lower as well as the activity of superoxide dismutase has been higher in all the groups almost in 1.5–2 times (Р ≤ 0.001).

Radical Oxidation

Recently, interest in the problem of free radical oxidation in biological membranes, which is directly related to both the normal functioning of cells and the occurrence, course and outcome of many pathological conditions, has increased again in clinical medicine. The aim was to determine the role and impact of antioxidant defense in boys with hypoandrogenism. The study involved 75 adolescents with hypoandrogenism aged 13–18 years, who underwent a complex of clinical and laboratory examinations. All patients were conducted complex of anthropometric research and determination of the degree of delayed puberty, laboratory and instrumental examination. Free radical oxidation was determined by the levels of malondialdehyde, conjugated dienes, carbonated proteins, superoxide dismutase and catalase in the serum, and restored glutathione and glutathione peroxidase in whole blood. Based on their determination, the coefficient of oxidative stress was calculated. Statistical processing of results was performed using parametric and nonparametric methods. The study of indicators of the free radical oxidation process found that adolescents with hypoandrogenism have multidirectional changes in the oxidation of proteins and lipids, namely: the level of conjugated dienes increases, the concentration of malondialdehyde remains at the level of the control group, and the level of carbonated proteins tends to decrease. As for the activity of antioxidant protection enzymes, a significant decrease in the level of glutathione peroxidase was detected, while the level of superoxide dismutase and catalase remained at the level of normative indicators. Oxidative stress accompanies and is one of the pathogenetic links in the formation or maintenance of the state of hypoandrogenism in boys. This requires the use of antioxidants, the complex of which must be selected individually.

The feasibility of using the complex mineral and vitamin feed additive “Nadezhda” in the rations of lactating first-calf heifers of Black-and-White breed has been examined in the article. It has been established that feed contain a low content of elements such as calcium, phosphorus, magnesium, sulfur, manganese, copper, zinc and cobalt. The ratio of nutrients and minerals, the degree of their availability for assimilation by the body does not provide their need. The use of the complex mineral and vitamin feed additive contributed to an increase in the milk productivity of first-calf heifers and the quality of milk, feed consumption per unit of production. All tested recipes of the complex mineral and vitamin feed additive, which have different versions of macro-, microelements and vitamins in their composition had a positive effect on the metabolic processes in the body of animals. For the production of 1 kg of milk in the experimental groups of cows less metabolic energy was spent by 5,09 (P < 0,05) and 8,06 % (P < 0,05), respectively, raw protein by 5,19 and 8,19 % (P < 0,05), digestible protein by 5,12 (P < 0,05) and 8,15 % (P < 0,05) compared with the animals of the control group. At the same time from the cows of the 1st experimental group have been received more milk by 151,6 kg in the amount of 2489 rubles, from the 2nd experimental group by 250,6 kg of milk in the amount of 4248,0 rubles. The prime cost of production of 1 kg of milk in cows of the 1st experimental group in comparison with the animals of the control group decreased by 0,72 rubles, and the 2nd experimental group by 1,21 rubles. The level of profitability of milk production in cows have been fed with additive recipe No. 1, in comparison with the animals of the control group increased by 3,71 abs.%, recipe No. 2 by 9,91 abs.%.

Modern environmental conditions dramatically increased the level of radical forming processes in the body. Heat exposure stimulates the generation of reactive oxygen species inducing peroxidation of lipids as a result of the development of hypoxia. In experimental conditions the possibility to correct free radical lipid oxidation of rats’ organism membranes was studied with the oral introduction of the phytoadaptogens that contain the complex of natural antioxidants. The animals were divided into 5 groups and each of them had 30 rats: intact animals (1) which were held in standard conditions of vivarium; the control group (2) in which rats were exposed to heat during forty-five minutes daily; the experimental groups (3, 4, 5) in which before the effects of heat animals had a daily oral intake of the extracts of Eleutherococcus, Rhodiola, liquorice in a dose of 1 ml/kg. It was found out that in the liver tissue of experimental animals a daily heat exposure during forty-five minutes contributes to the increase of lipid hydroperoxides level (by 34-41%), of diene conjugate (by 45-50%), and of malonic dialdehyde (by 62-74%) against the decrease of antioxidant system activity in the liver of intact animals. The introduction of phytoadaptogens to rats in the conditions of heat exposure contributes to the reliable decrease in the liver of lipid hydroperoxides by 22-28%, of diene conjugates by 22-32%, and of malonic dialdehyde by 30-37% in comparison with the rats of the control group. While analyzing the effect of the phytoadaptogens on the activity of the components of antioxidant system it was shown that the level of ceruloplasmin in the liver of animals was reliably higher by 68-82%, of vitamin E by 42-65% in comparison with the same parameters of the rats of the control group. So, the application of phytoadaptogens in the conditions of long heat exposure of the organism of animals under experiment leads to the stabilization of the processes of peroxidation against the increase of antioxidant system activity.

The article presents the results of studies on the effect of commercial food on the processes of free radical oxidation of lipids in the body of cats with urinary tract pathology. It has been found that the concentration of diene conjugates in the blood serum of sick animals increases significantly by 15.1 - 36.7% relative to healthy ones. The MDA content in the blood serum of healthy animals was 6.05 ± 0.28 nmol / g. In animals with urolithiasis, this indicator increased by about 2 times. When feeding with commercial food and homemade food, LPO processes normalize, which is most pronounced on the 21st day. The average activity of catalase in the blood serum of sick animals was increased from 30.6% to 40.2% relative to healthy ones (15.15 ± 0.61 ?mol / ml). After feeding with therapeutic and prophylactic fodders, by the 7th day, the catalase activity did not significantly decrease compared to the initial level, but remained higher than in control animals by 19.6% - 37.1%. On the 14th day, the catalase activity did not change significantly compared with the 7th day and was higher than the control values by 21.5% - 27.5%.

Objective: to study the main indicators of free radical oxidation and antioxidant protection in the erythrocytes of former athletes, depending on the period of termination of sports.Materials and methods: 24 former male athletes aged 19–29 years were examined, who were divided into 2 groups of 12 people each (1st group — former athletes who stopped training for up to 2 years; 2nd — over 2 years). The control group consisted of 15 practically healthy untrained student volunteers of the same age. In erythrocytes, spectrophotometrically (spectrophotometer Shimadzu 1240, Japan), the activity of antioxidant enzymes was determined: superoxide dismutase (SOD) (K.F. 1.15.1.1) — by inhibiting the reduction of nitro blue tetrazolium by superoxide anion radical at λ = 540 nm, after preliminary processing of erythrocytes by the method of Dubinina E.E. and others [8]; catalase (K.F. 1.11.1.6) — according to the rate of utilization of hydrogen peroxide at λ = 260 nm; glutathione peroxidase (HP) (KF 1.11.1.9) — by the change in the content of reduced glutathione in samples before and after incubation of the substrate with dithiobis-nitrobenzoic acid at λ = 412 nm; glutathione reductase (GR) (K.F. 1.6.4.2) — according to the catalytic NADPH ∙ H+-dependent transformation of the oxidized form of glutathione into the reduced form, the intensity of which was estimated by the rate of decrease in the extinction of samples at λ = 340 nm, at which the NADPH H+ solution has a maximum light absorption (Warburg test).Results: the direction of the shifts in the state of the oxidative balance was established depending on the period of detraining. A significantly lower value of the total antioxidant activity was revealed in the former athletes of the 1st group. This phenomenon is probably associated with a decrease in the efficiency of the enzymatic link of the antioxidant defense in the absence of regular physical exertion, and, as a consequence, an increased consumption of non-enzymatic antioxidants. It was found that the early post-sports period is characterized by significantly lower, in comparison with the control group, the values of the activity of the first-order enzymes (superoxide dismutase) against the background of the increased activity of the second-order enzymes (catalase).Conclusions: the obtained data can be recommended for monitoring the state of athletes who stopped playing sports and taken into account when prescribing rehabilitation measures for the corresponding contingent.

It is known that mineral additives play an important role in increasing the productivity and efficiency of the animal husbanry industry as a whole. The state of the body can be assessed by the content of mineral substances in a blood test. The purpose of the work was to study changes in morphological and biochemical blood parameters in first-calf heifers during the period of increasing the milk yield when they are fed a complex mineral and vitamin feed additive (CMVFA). The study of the influence of feeding the complex mineral and vitamin feed additive in the ration to first-calf heifers during the the period of increasing the milk yield on morphological and biochemical blood parameters has been carried out. The experiments were carried out in 2019–2020 in the OOO Breeding Farm “Valiev” in the Dyurtyulinsky district in the Republic of Bashkortostan on 3 groups of first-calf heifers of Black-and-White breed per 15 heads in each selected by the method of pairs of analogues. The animals of the control group received the main ration (MR) adopted on the farm, the 1st experimental group MR+120 g/head CMVFA according to the recipe No. 1, the 2nd experimental group MR+120 g/head CMVFA according to the recipe No. 2. In the ration of animals of the control group there was a deficiency of basic macro- and microelements. The use of CMVFA as part of the ration of first-calf heifers during the period of increasing the milk yield had a positive effect on the morphological and biochemical parameters of blood. Studies have shown that the use of CMVFA in the rations of first-calf heifers provided the need for minerals and vitamins, accelerating metabolic processes in the body during the most stressful period of lactation, the period of increasing the milk yield. According to the results of biochemical blood parameters, it is possible to esimate the improvement of protein, carbohydrate and mineral and vitamin nutrition in the first-cakf heifers of the experimental groups during the period of increasing the milk yield, which showed their genetic potential more fully and used nutrients more effectively for milk synthesis.

The purpose of researches is increase of meat efficiency of bull-calves of black-motley breed through the use of canned green mass of alfalfa with Laxil and Silostan when harvesting haylage. The results of the evaluation of the effect of alfalfa haylage harvested with preservatives on the efficacy of bioconversion of nutrients and energy rations in meat products. Scientific and economic experience held in the SEC-farm «Alga» Chekmagushevsky district of the Republic of Bashkortostan. There are three trench silage from alfalfa. In one of them the food was laid with the application of the preservative Laxil, the second – and third Silostan – no preservatives. Laxil preservative was added at the rate of 1 liter per 15 tons of green mass, Silostan – 1 liter to 150 tons. The object of research was 45 bulls of black-and-white breed at the age of 9 months, of which three groups were formed: control and two experienced. Gobies control group received silage of alfalfa harvested without preservatives, and the animals of I and II experimental groups – silage, preserved by Laxil and Silostan. For studying of meat productivity and quality of meat of test bulls control slaughter of 3 bulls from each group was carried out. The results of the study indicate the superiority of calves of the experimental group over their counterparts from the control groups both in vivo and post-slaughter parameters. The results of the evaluation of the transformation of protein and energy feed in the production of bulls compared groups when grown for meat indicate that in the body of young I and II experimental groups were deposited a little more protein compared with peers from the control group.
