Abstract: The two-mowing use of еру varieties spring wheat and triticale is studied, which aims to increase yield due to the growth of the biological component. The analysis of the elements of the crop structure and yield of wheat varieties "Riks", "Tyumen 29" and triticale varieties "Erythrospermum 56 /314", "Erythrospermum 57 /405"; "Erythrospermum 94 /1119", "Erythrospermum 112 /1020", which are promising for two-mowing use. The elements of the crop structure have been determined: total bushiness, productive bushiness, grain content of the main spike, grain content of а plant, plant length, as well as the yield of green mass and grain. As а method, one-mowing use was studied - with obtaining а grain yield and two-mowing use -with obtaining а yield of green mass and grain from one agrophytocenosis during the growing season. The studies were carried out in 2020, 2021 in the forest-steppe zone of Krasnoyarsk Territory. The years of research exceeded the norm in terms of the sum of active temperatures, 2020 was characterized Ьу а greater amount of precipitation of the growing season, 2021 - less in comparison with the average long-term value. On average for varieties, higher indicators of the elements of the structure of the yield were obtained with one-mowing use. Considering individual varieties, the differences were found: а higher grain content of the plant, total bushiness, and productive bushiness were in the variety "Tyumenskaya 29" with two mowing. There is no direct relationship between the yield of green mass and the length of plants, which сап Ье explained Ьу the influence of weather conditions on the regrowth of stems after mowing. With an average yield of green mass in 2021 of 16.3 t/ha, the length of the plants for harvesting was 90.3 cm. 1n 2020, the average yield of green mass was 6.9 t / ha with а longer plant length of wheat and triticale varieties of 99.7 cm. In the forest-steppe of the Krasnoyarsk Territory, with two-mowing use, all studied wheat and triticale varieties formed the grain yield at two­mowing use, which ranged from 59.3% for the "Tyumenskaya 29" variety to 132.0% for the Erythrospermum 56/314 variety.

Abstract: The effectiveness of the use of liquid mineral nitrogen fertilizers based on а carbamide-ammonia mixture САМ has been proven Ьу world and national science. The article presents more in-depth topical studies of Samara State Agrarian University (Samara SAU) on improving the efficiency of САМ Ьу adding the mesoelement-sulfur in comparison with solid mineral fertilizers-ammonium nitrate for the main crops: wheat, com, sunflower, soybeans with а comprehensive justification of the necessary innovative technological means (fertilizers), machinery and equipment (for application, transportation-logistics, storage). Also, the comparative field experiments made it possiЫe to assess the effect on the yield of the studied crops of liquid nitrogen-sulfur-containing mineral fertilizers САМ+ S (N-24-26%, S-3,6%) (to determine the effect of sulfur-S when added it to the САМ in а ratio of 1: 6 on average, for three years of research, indicators ). Thus, liquid mineral fertilizers based on САМ + S compared to solid ones-ammonium nitrate when applied fractionally before sowing and two or three times during the growing season, on average, have an effect on increasing yields: on hard spring wheat- Ьу 30%, soybeans - Ьу 47%, com - Ьу 33%, sunflower - Ьу16 In the new liquid mineral fertilizer based on САМ, sulfur-S is added, which is 3.6%, and nitrogen N in this fertilizer САМ CAМ +S in liquid mineral fertilizers based on САМ provides an additional increase in the yield of agricultural crops in comparison with pure САМ-32: hard spring wheat - Ьу 10%, soybeans -Ьу 9%, com - Ьу 5%, sunflower in our studies did not reveal а significant effect of sulfur-S in САМ on а significant increase in yield.

Abstract: Our previous studies have shown the prospects of using carbohydrates as biologically active substances that are suppliers of glucose for the tricarboxylic acid cycle. 1n the present study, the effect of carbohydrate solutions on the total protein content in germinating Tetra short rye seeds was studied. "Tetra short" rye seeds were germinated in water (control) and solutions of simple and complex sugars: monosaccharide (glucose), disaccharide (sucrose), polysaccharide (arabinogalactan). The content of total protein was determined Ьу spectrophotometric method. It was revealed that the germination of "Tetra short" rye seeds in solutions of simple and complex carbohydrates leads to an increase in the total protein content in the seedlings. The most pronounced positive effect was noted for glucose solutions, а smaller increase for sucrose solutions, and the minimum of the studied ones for arabinogalactan solutions. When germinating "Tetra short" rye seeds in solutions of glucose monosaccharide, the least hydrolysis of reserve starch in grains is noted. In general, the hydrolysis of reserve starch increases in а series of solutions: glucose - sucrose - arabinogalactan. The results of the study indicate that arabinogalactan, which is the least effective of the studied carbohydrates in relation to protein biosynthesis in "Tetra short" rye seedlings, has а pronounced positive effect on the formation of the root system of this plant. The mass of roots during seed germination in an arabinogalactan solution is 2.5 times greater than during seed germination in water, and almost 2 times higher than during seed germination in glucose solutions. Thus, the influence of the biologically active substances on the growth and development of plants is very multifaceted and depends on many factors, including the nature of the substance, the mechanism and direction of the processes occurring with its participation in the plant.

Abstract: The use of foliar top dressing with microelements in the form of а chelated fertilizer сап have а positive effect on plants and give а significant increase in the yield of potato and topinambur tubers. The objective of the study was to evaluate the effect of innovative preparations: sulfur-containing and with the content of microelements in the chelate form: Fe, Zn, Mn, Си, Мо, Со, В, on the yield parameters of potato tubers of the mid-ripening "Kolobok" variety; green mass and tubers of topinambur varieties "Interest" and "Podmoskovny". The studies were carried out in 2016-2018 on sod-podzolic sandy loam soil. In the experiment, the treatment of planting tubers and two non-root leaf treatments were carried out. То assess the effect of drugs on potato plants, in addition to control with water treatment, there was also а pure control option - without treatments. The use of the tested preparations increased the values of the mass of potato tops to 354 ... 392 g /bush under control of 325 g /Ьush; topinambur to 1.02 ... 1.20 kg /Ьush under control of 0.91 ... 1.10 kg /Ьush; increased the reproduction coefficient Ьу 1.8 .. .2.7 pcs./Ьush (18 .. .26%) to the control (potatoes) and Ьу 2.3 ... 14.4 pcs./bush (3 .. .21%) (topinambur); increased the value of the gross yield of potato tubers Ьу 3 .О ... 3 .3 t/ha (12 ... 13% ), topinambur Ьу 0.87 ... 3.13 t/ha (5 .. .23%), reduced total losses during potato storage Ьу 0.2 ... 1.4% and during topinambur storage Ьу 4.3 ... 37.4%. The data obtained confirm the expediency of using microelements in the chelate form in the cultivation of potato and topinambur tubers. То increase the number of tubers and improve the preservation of potato tubers, it is preferaЫe to use а sulfur-containing preparation, and for topinambur - а preparation with microelements Fe, Zn, Mn, Си, Мо, Со, В in chelated form.

Abstract: Goshawk studies were carried out on Altai Territory and in the Altai RepuЬlic during the 2005-2020 field seasons simultaneously with the study of other birds of prey. The habitats of the hawk have been estaЫished in the lower reaches of the Biya River (the vicinity of S. Zaozernoye), in the Pre-Altai plain (Zmeinogorsky district), in the foothills of the Seminsky Range (valleys of the Setovochka, Zhernovka and Bolshaya Biryuksa rivers, on the watershed on the left bank of the Peschanaya River), in the South-Eastern Altai (the valley of the Jazator River at the mouth of the Akbul River), as well as within the Salair ridge in the valley of the Chumysh River. Observations were made on 8 nests, in the foothills of the Seminsky Range -six (75.0%) nests were located on birches, and one each (12.5%) - on aspen and larch. All buildings were located in the lower or middle part of the crown at а height of 5.2-12.0 m from the ground, six of them (7 5. 0%) were in the f orks of birch and aspen trunks, two (25. 0%) were at the base of the lateral branches of birch and larch. The death of а goshawk from electric shock on power line supports throughout the RepuЬlic of Altai and Altai Territory has been registered. The database on the territorial distribution and abundance, habitats, nesting biology of the goshawk has been supplemented. The goshawk is а common but not numerous species in Altai. It inhabits for the most part the foothills and adjacent forest-steppe plains both in the breeding season and in winter. In the Southwestern and Northeastern Altai, it is quite гаге in all seasons of the year. The main limiting factors of the large hawk population are bird-hazardous power lines, forestry activities, damage from pesticides used in agriculture, and due to senseless shooting at the opening of the hunting season, as well as extermination under the false pretext of harmfulness, especially Ьу pigeon breeders. The data obtained сап Ье used to improve regional measures for the protection of biodiversity.

Abstract: Natural and climatic conditions and anthropogenic load determine the ecological state of the environment, as well as the health of the population living on this territory. The most critical situation has developed in cities, where air pollution plays а decisive role. In this regard, а comprehensive assessment of the impact of technogenic pollution on ecosystems, the development of methods and means of environmental monitoring, the study and assessment of the influence of abiotic factors and the resistance of organisms to technogenic impacts become relevant. The objective of the study was to identify the degree of anthropogenic pollution of the atmosphere and to assess the economic damage to the health of the population of an industrial region. Scientific novelty: а comprehensive environmental and hygienic assessment of the urbanized area was carried out from 2008 to 2017, including the degree of atmospheric air pollution, hygienic assessment of health risks, а comprehensive assessment of the health status of the population, economic calculation of some types of environmentally caused morbidity. Priority air pollutants include: magnesium, ammonia, iron, cadmium, manganese, copper, arsenic, nitrates, mercury, lead, and chlorides. During the study, the following methods were used: assessment of atmospheric air pollution from stationary sources; the degree of atmospheric air pollution was assessed Ьу а complex conditional indicator (Р) of atmospheric air pollution and а complex (К) indicator of atmospheric air pollution; the state of health of the population was assessed on the basis of the general and newly diagnosed morbidity of children, adolescents and adults, to calculate the environmental and economic damage from the morbidity of the population - а method for assessing the economic damage from the incidence of the population. The consequences of environmentally caused morbidity, disability and supermortality of the population, as well as temporary disability have an economic aspect. А full-fledged study of the interaction between puЬlic health and the economy of the region requires an objective assessment of economic costs, in connection with which we assessed the calculation of economic damage in the study area.

Abstract: At present, the taiga is increasingly exposed to anthropogenic and technogenic impacts (industrial logging, mining, oil and gas production, forest fires caused Ьу man). This article explores options for the sustainaЫe use of the forest potential of biological and recreational resources of the taiga nature management. The development of schemes and algorithms for increasing the efficiency of the use of these resources in the economic system -taiga nature management focused on integrated sustainaЫe forest management, taking into account the ecological functions of the forest, is becoming increasingly relevant. The proЫem­conceptual field of research is described on the basis of domestic and foreign sources. In terms of reflecting the results of the study, prospects for the development of recreational taiga nature management are being developed on the basis of the integrating position of taiga tourism. It seems possiЫe to create а regional network of taiga ecological villages for the year-round reception of tourists, which would Ье of great help in the revival of endangered taiga settlements. The reasons hindering the development of taiga ecological tourism are indicated. Two main options (intensive and extensive) of the combination of types of natural tourism and recreational taiga nature management, which сап serve as recreational zoning of forests of Irkutsk region, are presented. It is fundamentally possiЫe to create five clusters for the development of active nature-oriented tourism in forest areas in the region. It is necessary to initiate the reconstruction of the taiga nature management system based on the principles of sustainaЫe use and reproduction of non-timber forest potential.

Abstract: It is reported about the discovery of а new habitat of the гаге orchid Ponerorchis cucullata in the Ussuri urban district of Primorsky territory. Typical habitats for this species of orchid are coniferous and coniferous-deciduous forests with а developed moss cover. In the Ussuriisk urban district, Ponerorchis cucullata was found in an atypical place - in а Ыack-birch oak forest without mossy areas. The thickness of the litter layer is 3 cm, the soils are brown forest. The population on an area of 50 m2 is represented Ьу 27 individuals growing under the canopy of а sparse forest (crown canopy density is 65-75 %.) Ten flowering plants of this гаге species were noted; of them, 4 specimens of Ponerorchis cucullata grow in а group, the rest are distributed singly. On Primorsky territory, this species of orchid is known from а few habitats and was previously reported for the Ussuriysk urban district almost а hundred years ago. It is а гаге species included in the Red Book of the Russian Federation and regional Red Books. It is under special protection in eight Far Eastern nature reserves. It occupies an extensive Eurasian area. In the Russian Far East, the populations have а low number of individuals. The revealed habitat of this orchid plant is remote from the places of primary finds (Ussuriysky (Suputinsky) nature reserve, Suputinskaya dacha) at а consideraЫe distance of about one hundred kilometers. In the new locality, Ponerorchis cucullata is represented Ьу generative and immature plants with а total number of 27 individuals ( of which 1 О are flowering). It has been estaЫished that this habitat of Ponerorchis cucullata is characterized Ьу atypical growth conditions for this species (absence of moss cover). The discovery of а new population of Ponerorchis cucullata makes it possiЫe to expand the understanding of the distribution of this гаге species on the southeastem border of its range. The factors that threaten the conservation of the population of Ponerorchis cucullata in the Ussuri urban district of Primorsky territory are: the small number of the population, the economic use of land, and damage to the forest floor Ьу ground fires.

Abstract: Feed adsorbents, the list of which is updated annually, have proven to Ье effective drugs that prevent contamination of the meat produced when organizing the nutrition of young ruminants. At the same time, special importance is attached to their ability to Ье synergists with other feed biologically active additives (ВАА). Feed antioxidants are one of such preparations, which are also сараЫе of having а protective effect against heavy metals (НМs). The purpose of the research is to determine the effectiveness of the detoxification effect of the feed preparations chelaton (adsorbent) and santoquine (antioxidant) on the processes of intermediate metabolism in the body of bulls fed on diets with excessive levels of zinc, lead and cadmium. It was found that in order to increase the hematopoietic function, activate all aspects of metabolism in the liquid internal environment and improve the ecological safety of the body, the adsorbent chelaton in the amount of 1 g / 100 kg of live weight and the antioxidant santoquine in the amount of 500 g / t of compound feed should Ье j ointly introduced into the diets of bulls fed in the technogenic zone with an excessive background of heavy metal ions. This is confirmed Ьу an increase in the Ыооd samples of animals of the 3rd experimental group relative to the control group in the number of erythrocytes, hemoglobin, and sugar. Also, due to the better detoxification of toxic elements when feeding both drugs against the control, the young animals of the 3rd experimental group improved their fat and mineral metabolism. In the animals of the best experimental group, under the influence of an adsorbent and an antioxidant, а positive shift occurred in the protective properties of the liquid internal environment, due to which an increase in the number of albumins in their Ыооd serum Ьу 2.14% and □-globulins Ьу 1. 87% was observed. Due to this, in the Ыооd samples of bulls of the 3rd experimental group, а statistically significant (Р<О.05) decrease in zinc ions Ьу 2.06 times, lead - Ьу 2.24 times, cadmium - Ьу 3.00 times was observed.

Abstract: The article presents the results of the analysis of the structure of diseases and pathological states that caused the death of dogs and cats admitted to puЬlic and private veterinary institutions of the city of Ussuriysk in the period from 2018 to 2020. An analysis of the official data of veterinary reporting for 2018, 2019 and 2020, carried out using the Vet Manager program, showed that during the period under review, 43200 cases of visits to Ussuriysk veterinary institutions for various diseases of dogs and cats were registered. One thousand four hundred and forty cases (3.33%) of this number resulted in а fatal outcome. It was found that the largest number of deaths (including euthanasia) occurred in 2018 and amounted to 4.16% of the total number of small pets admitted. There is а tendency to decrease the number of deaths, which amounted to 2.9% in 2019 and 3.9% of the total number of applications in 2020. The main part (72.0%) of diseases or pathological states that led to the death of dogs and cats accounted for diseases of non-infectious etiology. На заболевания инфекционного характера пришлось 16.0%, травмы - 8.0%, глистную инвазию - 4%. Among diseases of non-contagious etiology, the most common cause of death was oncological pathology (24.0%), diseases of the cardiovascular system accounted for 20.0%, kidney diseases - 20.0%. The cause of death in 12.0% of cases was liver pathology, in 10.0% - obstetric and gynecological diseases, poisoning of various etiologies (8.0%) and allergic diseases (6.0%). Against the background of а decrease in overall mortality, there is an increase in the number of deaths caused Ьу oncological diseases (from 13.51% in 2018 to 25.0% in 2020).

Abstract: Milk productivity of cows is 50-60% determined Ьу the quality of feed and the usefulness of feeding. The use of unbalanced rations leads to а decrease in the productivity of animals, overconsumption of feed per unit of production, an increase in its cost and, ultimately, to а decrease in the efficiency of the industry. In this regard, feed additives are widely used, which replenish the missing elements in the diet of animals and increase the milk productivity of cattle. One of the ways to obtain high productivity from cows is the use of "protected" fats in feeding to enrich the diet with energy. Numerous studies have proven that the introduction of "protected" fats into the diet provides more efficient energy absorption, increases feed consumption, has а positive effect on the reproductive functions of cows and improves milk productivity. According to the results of the conducted studies, it was found that the milk yield of cows of the experimental group receiving "Ultrafat 100" is higher than in the control in the first month of lactation Ьу 0.7 kg, in the second - 1.4 kg, in the third - 2.3 kg, as well as the amount of milk produced during 3 months of lactation is higher Ьу 135.7 kg. The average fat percentage for the first three months of lactation in the control group was 3. 78%, and in the experimental group - 3.79%, which is higher than in the control Ьу 0.01 %. The average percentage of protein for the first three months of lactation was 3 .04% in the control group, and 3.03% in the experimental group. When recalculating milk for basic fat content, 3094.7 kg were obtained in the experimental group, which is 159.1 kg (5.4%) more than in the control group. Economic efficiency from the use of the feed additive "Ultrafat 100" per 1 head for the milking period amounted to 239.57 ruЫes. Fractional palm fats of the feed additive "Ultrafat 100" have а positive effect on milk productivity and indicate the expediency of its inclusion in the diets of lactating cows.

Abstract: Today, one of the proЫems of international discussion is "contaminated" livestock products. The lack of ecologically high-quality and clean animal products is one of the priorities in the field of veterinary medicine. In total, 6 samples of pork meat from the leading pig complexes of Buryatia were studied Ьу the express method. А positive result was found in sample No. 4. The color of the test tube did not change, the color remained purple. In sample No. 6, а questionaЫe result. The tube changed color from purple to yellow, but а purple ring formed in the top layer of agar. The remaining samples gave а negative result, the color in the test tubes changed from purple to yellow. The results obtained Ьу the express method cannot Ье considered accurate, because in sample No. 6 the result turned out to Ье doubtful (а purple ring formed). However, in the study of this sample Ьу ELISA and microbiological methods, this sample in the study for tetracycline showed а negative result. We believe that the result of the express test was questionaЫe due to the fact that this sample could show the presence of residual amounts of other inhibitory substances in it. In sample No. 4, а positive result was also not confirmed. Examining the same sample Ьу other methods, the amount of tetracycline was found within ассерtаЫе limits (less than 0.01 mg/kg). However, when processing the results taking into account errors and rounding, the result of sample No. 4 was 0.01 mg/kg. When examined Ьу microbiological and chromatographic methods, all samples gave а negative result. Thus, the East Siberian pig complex and the Nikolaevsky breeding plant do not violate the required regulations when producing products; the residual amount of tetracyclines in meat does not exceed the maximum permissiЫe norms of 0.01 mg/kg.
