The results of researches on the peculiarities of metabolism in the body of horses of Yakut breed in the winter and spring periods under the environments of Central Yakutia have been presented in the article. Physiological experiments on the digestibility of the main nutrients of the feed have been carried out in the winter (February) and spring (April) periods under the environments of the physiological yard in the Yakutsk Scientific and Research Institute of Agriculture named after M. G. Safronov with using the classical method. Five mares and five geldings of Yakut breed have been selected for researches. The average live weight of mares was 378–410 kg, geldings 394–403 kg. The experimental animals had average fatness. It has been found a higher intake of energy and the main nutrients of hay as a mono feed in winter compared to the spring period. At the same time pregnant mares in winter have been consumed 103,8±3,12 MJ of metabolic energy per head/day, which was 27,3 % significantly higher than in the spring period – 75,4±2,18 MJ (P ≥ 0,999). Geldings have been consumed in the experiment 67,70±2,85 MJ, which was by 43,7 % higher than in the spring period – 38,05 ± 4,40 MJ of metabolic energy per head/day (P ≥ 0,999). Experimental animals have been housed in stalls; there was no energy expenditure for movement, so the amount of energy consumed in winter indicates the production of heat in the animal’s body. Pregnant mares per 100 kg of live weight have consumed 31,5±4,11 MJ of metabolic energy or 33,3 % more than in the spring period – 21,0±1,98 MJ; geldings have consumed 27,69±1,12, which was 41,78 % significantly higher than in the spring – 16,12 ± 0,75 MJ (P ≥ 0,999). The high intake of metabolic energy into the body of Yakut horses in winter is explained by the manifestation of adaptive mechanisms that affect the effective metabolism for survival, adapted to frequent changes in weather conditions and sharp temperature changes. The established differences in the biochemical parameters of blood serum of horses of Yakut breed are associated with changes in the consumption and digestibility of basic nutrients and energy, depending on the ambient temperature.

Metabolism is the term employed to embrace the various physical and chemical processes occurring within the tissues upon which the growth and heat production of the body depend and from which the energy for muscular activity, for the maintenance of vital activity and for the maintenance of vital functions is derived (Best & Taylor 1950). The destructive processes by which complex substances are converted by living cells into more simple compounds are called catabolism. Anabolism denotes the constructive processes by which simple substances are converted by living cells into more complex compounds, especially into living matter. Catabolism and anabolism are part of all metabolic processes, the carbohydrate, fat and protein metabolism. The term anabolic refers only to substances that exert an anabolic effect on protein metabolism and are unlikely to cause adverse androgenic effects. They shift the equilibrium between protein synthesis and degradation in the body as a whole in the direction of synthesis, either by promoting protein synthesis or reducing its breakdown. The protein anabolic effect of anabolic steroids is not restricted to single organs but is the result of stimulated biosynthesis of cellular protein in the whole organism.

Introduction. Historically, pesticides are evaluated more strictly from a medical point of view than other chemicals. Since their features, such as deliberate introduction into the environment, the possibility of contact with them by large masses of the population, and the high biological activity determine their potential danger to humans. Purpose of research - study of the biological effect of a technical product derived from triazoles when it is repeatedly ingested orally in mammals (rats), establishment of inactive and active doses, justification of the permissible daily dose (DSD) for humans. Material and methods. In acute experiments, white rats were used, including 6 animals in the group. Tested dose: 500-4000 mg/kg of body weight. A chronic (12 months) experiment was performed on 80 male rats with a bodyweight of 180-190 g at the beginning of the study. Tested doses: 5.0; 16.0 and 55.0 mg/kg of body weight (1 control and 3 experimental animals, 20 individuals each). In the dynamics of the experiment, we observed the condition and behavior of animals, water, and food consumption, recorded the timing of death, changes in body weight, physiological, biochemical, and hematological indices. Results. Indices of the acute oral toxicity on the studied product LD50 male rats were 2250 ± 483 mg/kg body weight. The dose of 5.0 mg / kg of body weight was not found to cause significant changes in all studied indices. The doses of 16.0 and 55.0 mg/kg of body weight had a polytropic effect on the body in experimental animals. Discussion. The studied product for the acute oral toxicity refers to low-hazard compounds, the doses of 16.0 and 55.0 mg/kg of body weight has a polytropic effect on the mammalian body, causing changes in carbohydrate, lipid, and lipoprotein metabolism in the body of rats - was accepted as acting. The dose of 5.0 mg / kg of body weight, when administered in rats, there are no changes in all the studied parameters throughout the experiment, is accepted as invalid. Based on the inactive dose-5.0 mg/kg of body weight and taking into account the reserve factor of 100, we have scientifically justified DSD for a person at the level of 0.05 mg/kg. Summary. The conducted sanitary and Toxicological studies indicate the need to assess the toxicity of new technical products to the mammalian body, to increase the reliability of the developed hygiene standards in environmental objects and food products.

The body of  broiler chickens is characterized by a high metabolism, which promotes rapid growth and development, but their performance indicators are largely related to housing conditions, which are known to include a number of technological stressors. With the development of stress in the body of poultry changes the course of metabolic processes, which causes changes in all types of metabolism, including protein. The aim of the study was to determine the changes in individual indicators of protein metabolism in the body of broiler chickens against the background of combined stress when included in the diet “Reasil Humic Vet” + “Laktin” and “Reasil Humic Health”. At 13th day of life, all clinically healthy poultry were exposed to combined stress – revaccination (intranasal Newcastle disease) plus cold stress (for 60 minutes by air conditioning and 5 °C in the vivarium). Material for research was selected for 3 days after the action of the stress factor (stage of anxiety), 13, 20 and 26 days after the action of the stress factor (the resistance stage). The material for the study was blood plasma, which determined the concentration of total protein, as well as the content of albumin, globulin fraction (α1, α2, β, γ). It was found that 3 days after the action of stress in chickens of Control group the development of adaptive reactions is manifested by the stability of the total protein content and redistribution of the fractional composition of plasma globulins in the form of increased albumin and α2-globulins. At different stages of development of the stage of resistance in birds of Control group, the content of total protein decreases by an average of 14.6 % due to the content of albumin by 6.9 % and α2-globulins – by 15.9 %, against the background of increasing α1- and γ-globulins by 23.1 and 33.5 % with the stabilization of individual studied indicators at the final stages of development of the resistance stage. The use in the diet of broilers feed “Reasil Humic Vet”, probiotic feed supplement “Laktin”, feed “Reasil Humic Health” under the influence of complex stress helps to increase the intensity of protein metabolism in poultry with the development of adaptation syndrome, as evidenced by the growth of total protein on average by 37.8 % (P < 0.05) and albumin – by 17.0 % (P < 0.05), which indicates an increase in the intensity of protein-synthesizing properties of the organism. In different periods of stress in the blood of broiler chickens Research groups there is an increase in the ratio of individual protein fractions, especially the content of γ-globulins - an average of 21.3 % (P < 0.05), which indicates an increase in the immune status of their body with a predominance of numerical values in the Research 1 group of poultry.

An interest in plants of Amelanchier genus is stimulated by the necessity of search for plant sources rich in biologically active substances and possessing the ability to influence different physiological processes in a human organism. The article gives information about places of growth of different species of Amelanchier (Amelanchier Medic) and about the fact that its fruits contain high concentration of free sugars, relatively low level of organic acids, sufficient amounts of various vitamins and provitamins and a complex of mineral substances. Nutritive and biological value of Amelanchier fruits in complex may produce a beneficial effect on different biochemical and physiological processes of normal vital activity of a human organism. The data are given about a positive influence of enteral introduction of polysaccharides isolated from Amelanchier fruits, on different physiological processes that enhance adaptational reserves of an organism of experimental animals. In particular, it was shown that watersoluble polysaccharide complex (WSPC) of Amelanchier fruits activates erythropoiesis increasing the amount of erythrocytes and hemoglobin in blood of experimental animals and raises concentration of iron. WSPC improves physical working capacity and increases the body mass of experimental animals. Addition of watersoluble polysaccharide complex of Amelanchier fruits to blood of a healthy donor increases thermal, osmotic and peroxide resistance of erythrocyte membranes thus protecting cells against damage under action of adverse factors in the experiment. Fruits of plants of Amelanchier genus may be recommended to be used as a food additive or a product in dietary and prophylactic therapy.
