It  was made the research of the adaptive ability and natural resistance of Polissia meat breed animals, the area of their content was limited by the conditions of the lowland, forested and bogged territory of the Ukrainian Polissia and Precarpathian. Materials for analysis were selected with scientific publications and works, which reflect the issue of the breeding and maintenance of Polissia meat breed animals, as well as their own research on the natural resistance of cows. As a result of the analysis of the obtained  information, it was found out that the cows of the 1st experimental group of the high-growth type, they  possess a high potential of natural resistance, a somewhat lower resistance was detected in the cows of the intermediate type (II control group) and compact type (III experimental group). From these studies it emerges that there is the advisability of a comprehensive study of the type of constitution, since this determines the level of natural resistance and light resistance of animals. Only strong animals are able to be healthy, to give a viable and full-fledged offspring, to have high productivity, to withstand constant operational loads on the body and for a long time to be rationally operated with the greatest economic efficiency.

Scientific publications describe the positive effect of feed additives and pharmacological complexes on metabolic processes in the body of broiler chickens, in particular, on the protein composition of the blood, meat productivity and protein accumulation in meat. The Peak-Antistress feed additive developed at the Department of Morphology, Physiology and Pharmacology of the South Ural State Agrarian University allows to reduce the technological load on the poultry body by stimulating the general metabolism and complex antioxidant action. Experiments on the use of the feed additive Peak-Antistress were carried out on broiler chickens of the final hybrid of the Arbor Acres cross in an industrial-type poultry farm with floor technology. The poultry was divided into three groups of 6,000 chickens each and kept in one workshop in separate sections. The control group received the main diet, the 1st experimental group received the main diet and feed additive at a dose of 1269 g / t of feed 5 days before slaughter, the 2nd experimental group received the main diet and feed additive at a dose of 1693 g / t of feed 5 days before slaughter. Slaughter of broiler chickens was carried out according to the technological instructions of the enterprise on the 38th day. Against the background of the use of the feed additive in the experimental groups of broiler chickens, stimulation of protein metabolism was observed, as evidenced by an increase in total protein in the blood by 7.9–20.1%, an increase in the level of protein in white meat by 0.1–0.3%, and a tendency to an increase in amino acids in white meat protein by 0.2–12.3%.

Currently, it is important in aquaculture to study and use products and additives, which have positive effects on the digestibility of nutrients by helping to normalize the intestinal microflora, thereby modulating fish immune response. The aim of the study was to assess the effect of a prebiotic based on mannan oligosaccharides produced from the outer walls of Saccharomyces cerevisiae cells on the histological structure, morphometric state of the intestine and activity of cellular and humoral components of nonspecific resistance of age -2+ carp. The experiment was conducted in four analogous ponds, which were stocked with age-1 scaly carp with an average weight of 55–58 g with a stocking density of 1000 fish/ha. Carp had been fed balanced compound feed for 60 days. Experimental groups of fish were fed with a prebiotic as a feed additive in the amount of: 0.025 % – Experiment 1, 0.05 % – Experiment 2 and 0.075 % – Experiment 3. Use of the studied prebiotic did not damage the intestinal histological structure of carp of the experimental groups. The villi height and intestinal crypt depth of carp in Experiment 1 (P < 0.05) and Experiment 2 (P < 0.01) were larger compared to the control group. Experiment 3 showed destructive changes in intestinal mucosa. The results of histological examination indicated the effectiveness of the use of the studied prebiotic in the amount of 0.025 and 0.05 % in the diet of age -1+ carp due to the absence of pathological changes and active morphofunctional state of the intestine, which, in turn, had a positive effect on feed absorption and metabolic processes in fish body. Analysis of the indicators of cellular and humoral links of natural resistance showed that in carp of the second and third experimental groups lysozyme activity of serum was 5 and 11 % (P < 0.001) higher than in the control group. Similar changes, though found in a greater extent, were recorded in the study of bactericidal activity of blood serum, especially in individuals of the second and third experimental groups (by 6.8 (P < 0.01) and 15.2 %). While with carps of the third experimental group, which used a prebiotic drug in the amount of 0.075 %, the content of CEC was 20.5 % higher than in the control group, which indicates an additional antigenic load on the body and is an unfavorable diagnostic factor. At the same time, with the fish of the second experimental group, which received, respectively, 0.05 % of the supplement of the drug “Actigen” to the main diet, probably higher phagocytic activity of blood neutrophils was recorded. A direct dependence of the growth of the phagocytic index and the phagocytic number of neutrophils on the dose of the studied prebiotic was detected. Immunological studies indicated a dose-dependent effect of the prebiotic on the activity of cellular and humoral components of non-specific resistance of carp. Given this, for the effective functioning of innate protective mechanisms, for the increase of the body's immune potential and productivity, it is most appropriate to apply to the diet of carp prebiotic supplement “Actigen” in the amount of 0.025 and 0.05 %.

This article presents the results of studies conducted on piglets with the inclusion of natural feed additives in the diet in order to prevent and correct metabolism. The first experimental group of piglets received a total diet consisting of fullfledged compound feed, a complex micro-feed product consisting of blue-green algae Spirulina, dihydroquercetin and organic iodine, the second experimental group additionally received Spirulina and dihydroquercetin. The introduction of these natural feed additives into the diet of piglets helped to increase the adaptive ability , correction and prevention of metabolic disorders in the body. In these studies, dacha feed supplements prevented hyperbilirubinemia. As a result, the concentration of total bilirubin in the blood serum of pigs of the first experimental group was 1% lower, in the second experimental group it was 13,7% lower than in the control group. They also had a positive effect on the functional state of the liver, as evidenced by a lower content of AlAT and AsAT activity in the blood serum compared to those in piglets of the control group with a close cholesterol-forming fraction. The animals of the experimental group were less ill and the safety of this group was 100%, in the control group it was 90%. The average daily increase in live weight of pigs for 90 days in the first experimental group was 1% higher than in the control group, and in the second experimental group it was 21,7% higher.

A rational system of rearing of replacement heifers taking into account their biological characteristics, should contribute to normal growth, development, the formation of high productivity and a strong constitution, and the extension of their longevity. The use of intensive rearing has a positive eff ect on the natural resistance of replacement young cattle. The purpose of the researches was to analyze the use of bentonite clay as a mineral additive in the rearing of young cattle. Scientifi c and economic experiment has been carried out on heifers of Black-and-White breed in the pasture period. Two groups of heifers have been formed based on the principle of analogous pairs, taking into account their origin, age, body weight and health status. Animals of both groups have been received the main economic ration during the rearing period, while heifers of the experimental group have been received a bentonite additive of 50 g (2,0 %) per head per day, control animals did not receive this additive. Experiment has shown that the experimental animals had a high growth rate. Up to 3 months of age the live weight of animals in both groups increased almost evenly. The average daily gain was in the range of 600–900 g. At the age of 4 months the average daily gain in body weight was 550 g in the control group, and 800 g in the experimental group. The diff erence between the groups was 250 g or 45,45 %. The highest average daily gain at the age of 6 months was in the animals of the experimental group and amounted to 1060 g, which was by 127 g or 13,61 % more than in the control group. Feed costs in the control group amounted to 6411,92 rubles, in the experimental group 6392,22 rubles, which was 19,70 rubles or 0,31 % less than in the control group. Thus, there were no signifi cant diff erences in the cost of feed between the groups. The prime-cost of 1 kg of live weight gain of heifers in the experimental group was less by 7,02 rubles or 9,26 %. In general, the level of profi tability of rearing of heifers in the experimental group was higher by 12,11 %, compared to the control group.

Summary. The disbalanced feeding and the uneven distribution of micro- and macroelements in the environment leads to a trace element, in particular hypomelanosis. To accelerate the growth and preservation of young farm animals include in the diet of various biological additives and drugs, which include selenium. For stimulation of weight gain in the livestock industry, as well as for the prevention and treatment of pathological processes in addition to micro - and macrouse amino acids, primarily methionine. The aim of this work was to study the influence of composition of DAFS-25+Polizon on morpho-biochemical parameters of blood and functional state of the liver in fattening bulls of black-motley breed in the conditions of the Republic of Bashkortostan. Experiments using were conducted on bull-calves of black-motley breed of the properties in the properties age from 6 to 15 months. The first experimental group during the experiment was additionally given the composition of DAFS-25+Polizon at a dose of 2 mg/kg, the animals of the control group received a standard diet. To assess the impact of the composition DAFS-25+Polizon on metabolism cattle studied morphological and biochemical indicators of blood and conducted histological examination of the liver. It is established that the use of the composition of DAFS-25+Polizon at a dose of 2 mg/kg increases the number of erythrocytes and hemoglobin in the experimental group and reduces the amount of white blood cells. The serum content of total protein, phosphorus and calcium increases in the group of experimental animals. Microscopic examination of the liver revealed no changes in the structure of the organ and hepatocytes in the experimental group, whereas in the control group hemodynamic disorders and dystrophic changes in liver cells were observed. Thus, the use of the composition DAFS-25+Polizon at a dose of 2 mg/kg of live weight in fattening bulls black-and-white breed contributes to the increase of redox processes in the body, stimulation of metabolism, prevent the development of liver disorders of cellular mechanisms of metabolism, optimizes the structure of the liver, which generally provides higher productivity.

Mineral Feed Additives

Animals imported to Yakutia from other regions fall into feeding and housing conditions that differ from their usual agro-climatic conditions, which causes the problem of their adaptation. Yakutia is one of the areas where the feed of its own production has a lack of basic minerals, which affects the health and productivity of animals, which has an additional negative influence on the adaptation process of imported cattle. In order to replenish macro- and microelements in the body, it is necessary to introduce various local mineral feed additives, premixes, and use mineral salts into the ration. Under the conditions of Central Yakutia the influence of local mineral feed additives (zeolite of the Khonguruu Deposit in the Suntar district and sapropels of local lakes) containing macro- and microelements that increase the meat productivity of steers has been studied. As a result of the research the influence of local mineral feed additives on meat productivity and physiological condition of Hereford steers has been established. Influence of zeolite and sapropel in a complex with mineral salts on digestibility of nutrients of the ration and use of nitrogen, calcium and phosphorus by experimental animals has been defined. The influence of feed additives on the quality of meat products has been studied. The results have shown that the use of local mineral feed additives in the composition of ration of steers during the fattening period at a dose of 0,7 g zeolite per 1 kg of live weight of the animal and 200 g of sapropel in combination with 10 g of mineral salts contributed to the gain in live weight, carcass weight, carcass yield, yield of edible parts, and economic efficiency of fattening. For the entire period of the experiment the gain in live weight in groups was: in control group 2222,9 kg, in the 1st experimental group 2396,2 kg, in the 2nd experimental group 2471,1 kg. The total economic effect for the 1st experimental group for the period of experiment amounted to 44,3 thousand Rubles, for the 2nd experimental group 78,0 thousand Rubles or per 1 head/day 14,06 and 24,76 Rubles, respectively.

Mycotoxins have been formed in feed are secondary metabolites of fungi and are quite stable substances that have teratogenic, mutagenic and carcinogenic effects. An effective way to combat mycotoxins in feed is the use of feed additives that adsorb toxins, prevent their absorption in the gastrointestinal tract of the animal and are excreted from the body. The infl uence of coconut enterosorbent Shelltic Es on fattening and meat qualities of young pigs has been studied. It has been found in the process of fattening that the highest feed digestibility was in pigs of the experimental group, in the diet of which enterosorbent has been added. The results of studies of the chemical composition and technological properties of pork have been provided. The positive eff ect of enterosorbent on precocity, absolute average daily gain of live weight and reduction of feed expenditures per 1 kg of gain has been revealed. In pigs from the experimental group the average thickness of the fat was higher and the area of the “muscle eye” was lower compared with animals of the control group, which indicates that higher rates of carcass yield have been obtained due to faster accumulation of fat tissue. The weight of internal organs of pigs indicates the intensity of metabolic processes in the body. In experimental animals the weight of the lungs was 0,1 kg lower, and the liver and heart were higher by 0,13 and 0,01 kg, respectively. Enterosorbent had no effect on the content of vitamins in the liver of pigs of the compared groups. The content of impurities of organochlorine toxicants and toxic elements in the meat and liver of animals of the experimental group was lower than that of control analogues. Therefore, the use of enterosorbent Shelltic Es promotes more active excretion of them from the body.

AbstractWe explored how viewing one’s anthropometric virtual avatar would affect the viewer’s self-body perception through the comparative evaluation of self-concepts—self-esteem and self-compassion, within the framework of allocentric lock theory. We recruited 18 female adults, aged 18–21, who identified themselves to have some level of body image concerns, and who had had no clinical treatment for their body image. Participants were randomly assigned either to the experimental or control group. The experimental group participated in both body positivity program and virtual avatar program, whereas the control group attended the body positivity program, only. The results affirmed that the body positivity program served as a psychological buffer prior to the virtual avatar stimulus. After the virtual avatar experience, the participants demonstrated self-acceptance by lowering their expectation on how they should look like. The findings from exit interviews enriched the quantitative results. This study verified the mechanism of the altered processing of the stored bodily memory by the egocentric sensory input of virtual avatars, and offered practical potential of the study outcomes to be applied in various emerging fields where novel applications of virtual 3D technology are sought, such as fashion e-commerce.

Background. Balance and functional abilities are controlled by both sides of the body. The role of nonparetic side has never been explored for such skills.Objective. The objective of the present study was to examine the effect of a motor therapy program primarily involving the nonparetic side on balance and function in chronic stroke.Method. A randomized controlled, double blinded trial was conducted on 39 poststroke hemiparetic subjects (21, men; mean age, 42 years; mean poststroke duration, 13 months). They were randomly divided into the experimental group(n=20)and control group(n=19). The participants received either motor therapy focusing on the nonparetic side along with the conventional program or conventional program alone for 8 weeks (3 session/week, 60 minutes each). The balance ability was assessed using Berg Balance Scale (BBS) and Functional Reach Test (FRT) while the functional performance was measured by Barthel Index (BI).Result. After intervention, the experimental group exhibited significant(P<0.05)change on BBS (5.65 versus 2.52) and BI (12.75 versus 2.16) scores in comparison to the control group.Conclusion. The motor therapy program incorporating the nonparetic side along with the affected side was found to be effective in enhancing balance and function in stroke.
