The purpose is to studying the response of oats to soil drought by the degree of change in the content of protein nitrogen in the leaves and identifying the most drought-resistant varieties for the breeding process. Methods. In the experiment, 40 varieties of oats were used, for which soil drought during tillering and flowering was artificially modeled. Determination of protein content in oat leaves was carried out on the twelfth day after the cessation of irrigation, using the Bradford reagent. Results. The reaction of oats to soil drought in the critical phases of ontogeny (tillering and flowering), expressed as a change in the protein content in the vegetative parts, was studied. On average for the collection, the protein content in tillering was 13.6 %, varying from 10.3 to 16.9 %. In flowering, this indicator decreased to 6.6–14.4 %. It was established that soil drought during the tillering period had a minimal impact on the varieties Assol’, Novosibirskiy 5, Ulov, KROSS, Fakel, Sig, Privet, Megion, Barguzin and Argument. The decrease in protein content in these varieties varied from 7.4 to 10.8 %. In the varieties Pesets, Uran, L’govskiy, Bulanyy, Tigrovyy, Ekspress, Dedal, Narymskiy 943, Pokrovskiy 9, Rovesnik and Borets, soil drought during tillering led to a decrease in the protein content in the leaves by 20.4–30.8 %. The varieties Sig, Ulov, KROSS, Chizh, Novosibirskiy 5, Megion and Fakel were the most resistant to drought during flowering. During the analysis of the data obtained, it was revealed that the varieties L’govskiy 82, Privet, Peredovik, Assol’, Ulov, Novosibirskskiy 5, and Sig reacted to a minimum degree to drought during tillering and flowering.

The article presents the results of the study of essential oil-bearing rose samples according to the most valuable indicators. The purpose of the current research was twofold: characterize essential-oil-bearing rose collection in terms of the morphobiological parameters and economically valuable traits; identify samples promising for selection. Research methods. Analysis of essential-oil-bearing rose samples was carried out according to the methodological guidelines for essential oil crops in 2017–2020. Under field and laboratory conditions, we analyzed such indicators as flowering time, winter hardiness, budding ability, flower weight, essential oil content in inflorescences. Statistical processing of the data obtained was carried out. Results. The essential-oil-bearing rose collection nursery was laid in 2012 at the experimental site of the Department of Aromatic and Medicinal Plants located in the foothill zone of Crimea (Krymskaya Roza vill., Belogorskiy district). Significant variability of the flower weight and mass fraction of essential oil (Cv = 24.6…36.3 %) was noted. The dependence of the main indicators on meteorological conditions during the period of active vegetation of plants was analyzed. It was found that extremely high temperature regime and insufficient rainfall in April–May reduced the duration of flowering in the essential-oil-bearing rose collection, on average, by 3–5 days. It was noted that, despite the differences in the response of samples to weather conditions, the leading factor determining the level of essential oil accumulation in inflorescences is genotype. According to the complex or individual valuable indicators, we identified 14 best specimens, seven of which were with the highest content of essential oil in inflorescences (0.030–0.049 %). Scientific novelty. For the first time, a one-time detailed study of the collection was conducted according to a set of valuable traits. The collection comprises 50 specimens including five varieties of Crimean breeding (originator – Research Institute of Agriculture of Crimea) and five – from Bulgaria. The information obtained will allow selecting samples that are promising as source material for breeding, as well as predicting the expected productivity of essential-oil-bearing rose varieties under specific weather conditions of the region.","PeriodicalId":125083,"journal":{"name":"Agrarian Bulletin of the","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139270089","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Increasing the productivity of poultry, an important issue of ensuring the fulfillment of tasks under the Doctrine of Food Security. The purpose of the work was to study the effectiveness of the use of Ares biotechnological additive (dietary supplement) in the cultivation of broiler chickens for their weight growth, taking into account gender. Methods. Scientific and production experience was carried out in the conditions of the poultry workshop of the educational and experimental farm of the Ural State Agrarian University on the poultry of the Kobb 500 cross. The duration of the experience is 38 days. We studied the productivity of broiler chickens in terms of growth in comparison with the requirements of the cross standard, depending on gender. The live weight was determined by weighing 10 heads in each subgroup, selected by random sampling (5 heads of each sex). Results. All chickens, regardless of the group, increased their live weight with age, reaching 2632–2880 g by the end of cultivation, which meets the requirements of the cross standard. The highest live weight was obtained in the 2nd experimental group, where dietary supplements “Ares” were used in dry form in the amount of 300 g per 1 ton of compound feed (P ≤ 0.05). In all experimental groups, chickens were inferior to cockerels in terms of live weight at the end of the studies. The difference was significant at (P ≤ 0.05, 2nd experimental group; P ≤ 0.01, control and 1st experimental group, in favor of cockerels). Chickens from the 2nd experimental group significantly outperformed chickens from other groups in live weight at P ≤ 0.01 and P ≤ 0.05. Among the cockerels, the best results in achieving the maximum live weight during the research period were also achieved in the second experimental group, where the “Ares” biotechnological additive was used in dry form at a dose of 300 g/t. The scientific novelty of the work is determined by the fact that studies have been conducted in the context of the sex of broiler chickens and reference indicators of growth intensity in chickens of different sexes have been obtained when using the biotechnological drug “Ares”.","PeriodicalId":125083,"journal":{"name":"Agrarian Bulletin of the","volume":"31 4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139269527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The global brewing industry has recently undergone a series of changes, both related to the impact of the coronavirus pandemic (for example, the development of online sales), and based on structural changes caused by changes in consumer demand (reduction in total consumption due to the expansion of various alternative products, growth craft breweries, increased consumption of premium beer, etc.). The authors set a purpose to explore the industry for further use of information in order to establish the impact of new trends in the brewing industry on the hop industry. Methods. The calculations were carried out using the methods of statistical analysis of data from international and Russian official Internet resources. Scientific novelty. The main consumers of hop products are brewers. Accordingly, the identification of trends in the development of the brewing industry will serve as a good information base for making decisions about the direction of development of hop-growing. Results. Taking into account the global trend of accelerated development of craft brewing (China, USA), we can make an unambiguous conclusion about the great prospects for the development of aromatic hop varieties. In China, craft beer consumption is expected to triple by 2025. In the USA, consumers also prefer beer with unique flavors to the already fed up traditional beer drinks. Transnational companies, in turn, are trying to get out of the situation by making their products cheaper. In Brazil and Mexico, the main market share is occupied by subsidiaries of the large transnational company AB InBev. The German market has stabilized for a long time, a small negative dynamics of the market volumes is caused by a large number of alternative drinks. In Russia, beer consumption per person is also decreasing. However, beer sales in value terms continue to grow (mainly due to price growth). As of the beginning of 2022, 70 % of the Russian market was accounted for by transnational companies, which are the main consumers of hop extracts, the production of which is technologically more difficult than the production of hop pellets.","PeriodicalId":125083,"journal":{"name":"Agrarian Bulletin of the","volume":"1 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139268926","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose is to study the influence of the hepatoprotective phytocomplex on the severity of endogenous intoxication in laboratory rats with experimental liver pathology caused by hydrazine. Methods. The studies were carried out on non-linear rats, formed into 3 groups (n = 10). Toxic damage to the liver in rats of groups 1 and 2 was modeled by a single intragastric administration of hydrazine at a dose of 200 mg/kg of body weight. Immediately after intoxication and for the next three weeks in 1st group, the drug fitosomin was used – daily orally in the form of boluses at a dose of 0.5 g/kg of body weight, 2nd group after intoxication received empty cereal boluses, 3rd group was intact. In dynamics, the degree of endogenous intoxication was studied by the concentration of medium mass molecules (MMM) in the blood of animals at λ = 254 and 280 nm. Scientific novelty. Experimentally new data on the pharmacological effects of the hepatoprotective phytocomplex was obtained, which includes lecithin, dihydroquercetin, extracts of milk thistle, agrimony and golden boletus. For the first time, the effectiveness of the drug fitosomin was determined to reduce the severity of the endogenous intoxication syndrome in laboratory rats with experimental liver pathology caused by hydrazine. Results. It has been determined that hydrazine-induced liver pathology in laboratory rats is accompanied by the development of endogenous intoxication syndrome with a more pronounced increase in the blood fraction of MMM 254 relative to MMM 280. The use of fitosomin leads to a weakening of the toxic effect of hydrazine both on the liver and on the body of animals as a whole. The course application of the hepatoprotective phytocomplex increases the survival rate of rats, improves their clinical condition and leads to a decrease in the concentration of MMM in the blood. The obtained results outlined the prospects for the use of the drug fitosomin in veterinary practice in case of liver damage, as well as intoxication of animals.","PeriodicalId":125083,"journal":{"name":"Agrarian Bulletin of the","volume":"8 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139266560","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nosema is an infectious disease caused by the microsporidia Nosema cerana and Nosema apis. Adult bees get sick, as a result of which the family weakens and dies. Spores of N. cerana and N. apis, when infecting bees, penetrate into the middle section of the intestine, where the development of vegetative forms of pathogens occurs. The latter predominate in the epithelial cells of the mucous membrane of this part of the intestine and feed on their protoplasm. As a result, epithelial cells die off, as a result of which the intestine loses its functional activity, leading to the weariness of the bees. Families with nosematosis weaken, lose viability, and eventually die. Therefore, the development of measures to combat nosematosis is relevant. The purpose of the study was to study the spread of nosematosis in bees in the conditions of the Northern Trans-Urals and the development of therapeutic and preventive measures. To achieve this goal, the following tasks were set: determine the epizootological state of apiaries located in different natural and climatic zones in the south of the Tyumen region; to establish the effectiveness of therapeutic and preventive measures against nosematosis using herbal remedies. Methods. The work was carried out in the apiaries of the Tyumen region and in the IBiVM laboratory. In order to create an epizootic state of apiaries, bees were sampled in the apiaries of the southern taiga, subtaiga and forest-steppe climatic zones of the Northern Trans-Urals. Adult bees were selected for the study (in the amount of at least 10 % of the total number of bee colonies in each apiary). Experimental work was carried out in accordance with the “Methodological guidelines for setting up experiments in beekeeping” and “Methods for conducting research work in beekeeping”. Results. The data obtained characterize the high degree of infection with nosematosis of bees living in the northern regions. As a result of the research carried out in the laboratory of the State Agrarian University of the Northern Trans-Urals, phytopreparations have been developed, consisting of the flowers of medicinal plants (Achilléa millefólium and Tussilágo) with the juice of Állium satívum. These ingredients help to increase the resistance of families, increasing their viability and resistance to nosematosis.
