Brucellosis is a common bacterial zoonosis caused by Brucella spp., which are facultative intracellular gram-negative cocco-bacilli, causing disease in cattle, small ruminants, and humans. The occurrence of brucellosis is widespread across a wide geographical area as well as endemic throughout the Caucasus region. The Ministry of Agriculture of Armenia has adopted a diagnostic algorithm consisting of screening samples with the Rose Bengal Test (RBT) followed by confirmation with the complement fixation test (CFT). This study determined the feasibility of the algorithm and diagnostics in Armenia. Sampling and testing were conducted in two marzes of Armenia with disparate brucellosis prevalence. The screening was performed in 2020 at regional laboratories, followed by retesting at the reference laboratory with RBT and confirmation by CFT. Results indicated that RBT testing was reproducible between laboratories, although positive rates in CFT testing were slightly higher. Brucellosis incidence in cattle was not geographically dependent, while sheep incidence was affected by location. The addition of CFT to the diagnostic algorithm improves the results.

The data of the study indicate that the service period of the cows of the 4th-5th lactation is 5-58 days higher than the norm in the “Vamaks” LLC cattle farm of the Syunik region of the RA, and the coefficient of reproductive ability varies in the range of 86.3-98.6 %. Due to sterility, the loss of lactations in the 5th lactation is 16 and the loss of milk quantity is 126 tons. We propose to identify and inseminate (mate) animals with sexual desire in a timely manner, as well as to establish strict veterinary control to monitor and regulate the service period of 4-5 calving cows.

The research was carried out in the Ashtarak and Avan communities of the Aragatsotn region of the Republic of Armenia. During the research enterobacteria were found in the samples brought from the Ashtarak community. Salmonella, Escherichia coli, or Proteus diseases were suspected. API 20 E microbial identification test-system was used for identification. As a result of research carried out in 2022, using the above method, Escherichia coli was confirmed in bees in the Ashtarak community of the Aragatsotn region. The susceptibility of the pathogen to antibiotics was also checked and it was found out that the most effective antibiotics are Gentamicyn, Levofloxacin, Streptomycin, and Amoxicillin.

Research in this area aims to develop a milk-protein product similar to ricotta cheese. This product will be the second component of the newly developed twocomponent Yogrik product, a mixture of yogurt and ricotta. Combination of the biological value of yogurt and ricotta will create a balanced amino acid food. Cheeses obtained by acid and thermo-acid coagulation are usually fresh soft cheese varieties made by the coagulation of milk, cream, whey, or their mixtures, by direct chemical acidification, bacterial cultures coagulation, or by a combination of chemical acidification and high-temperature processing. In appearance and production technology, ricotta is between cheese and cottage cheese. But in terms of the softness of the clot and versatility, it is an outstanding product. Ricotta is rich in proteins including albumin and contains about 11 % protein. Whey cheese proteins are in the most easily assimilated state. Combining the biological value of yogurt and ricotta will create a balanced food with amino acid content.

The current work presents the distribution patterns of rare plant species and the mapping results with the help of the R programming language. In addition, it considers the topographical features of the RA mountain meadow zone. Taking the advantages of the R program capacity and the results of environmental studies of the given area, ways of solving several environmental problems related to the preservation of rare plants and biodiversity, depending on meteorological (Tmax, Tmin, RH, V) and soil moisture indicators were developed. The analysis was made with the data of Kajaran (1843 m) and Jermuk (2064 m) hydrometeorological stations, based on which the assessment of moisture availability of rare plant species was conducted, and the most dangerous periods for the development of life and growth of the mentioned plants were revealed. In particular, for plants at an altitude of 1800-2000 m, it was 75-130 days, and for those at the altitude of 2000 m, it was 60-110 days. Geospatial data analysis was performed, which allows to analyze and visualize environmental data through a cartographic representation. The use of comprehensive open source code for land use change assessment, landscape monitoring, ecological trends, and environmental problem identification is considered relevant, as it enables to avoid the use of narrow professional and expensive programs.

Cars have become an integral part of human civilization today. In developed countries, it is not only regarded as the main form of transportation, but also as a basic component of daily life. In spite of the rapid progress in motorization at the beginning of the 21st century, its apparent optimism brought tangible negative consequences as well. The study indicates that due to the sharp increase in the number of vehicles, loads on Yerevan, s roads have increased. The efficiency of transport use has decreased, whereas accidents, traffic jams and kneading have became more frequent. In 3-4 years, a transport collapse is inevitable if appropriate measures are not taken. To improve the traffic management, it is necessary to develop a strategy and implement a set of measures to improve the road network, especially road traffic, by using modern technologies, since expanding the road network is expensive, laborintensive, and not always possible.

The study was conducted on Holstein cows, which were imported from Germany and kept in the “smart” barnyard of the “Pepi Agro” farm at the Armavir Marz of the Republic of Armenia. According to the results, during the first lactation, 5827 kg of milk was yielded, fat and protein contents in milk were 3.82 and 3.27 %, live weight was 535 kg, and milk yield was 10.9 with the average milk flow rate of 2.37 kg/min. According to the 1990 appraisal, these cows exceeded the standards of the Holstein breed in terms of milk yield, fat, and protein content, as well as live weight. However, their milk yield was lower than the mothers bred in Germany by 2933 kg or 50 %. We propose to continue the importation of Holstein cows and their further breeding in “smart” farming conditions in the Republic of Armenia.

In comparison with other infectious diseases of dogs, parvovirus enteritis is quite common. The infection is periodically detected in animals in veterinary clinics. Observations have shown that unvaccinated puppies of 3-4 months are more often admitted to the clinic with parvovirus enteritis. In contrast to the 70 % rate indicated in the literature, the mortality rate among sick dogs reaches 50 to 93.3 %. Parvovirus enteritis can be treated with specific immune serums alongside symptomatic and pathogenetic therapies which increases the treatment efficiency up to 25 %. Additionally the combined use of immune serums and dexamethasone along with the described preparations – up to 50 %, which indicates the need for long-lasting use of glucocorticoids to increase adaptive functions of the body in dogs with parvovirus enteritis.

In recent years, in Armenia, meat has become more important than other food-producing directions of sheep breeding, which is due not only to lower costs and the demand for the domestic market but also to the export of many sheep from the republic. Consequently, foreign breeds of mutton, such as Dorper, Hisar, Romanov, Blanch Central Massif, etc., began to be imported and bred in Armenia due to their profitability. On October 20, 2021, Blanche sheep from the Central Massif was imported to the Balahovit ANAU experimental farm. A sheep was mated with a female weighing 80 % of the live weight of an adult queen, about 45-50 kg, and a male weighing 80-85 kg. There was an average or above-average fat level in the animals. Live weight, the amount of feed needed, the level of feed intake, the ability to adapt to weather conditions and reproductive performance were studied. Methods used in animal husbandry were used in the studies. When the animals were moved, they lost about 2.6 % of their weight during the initial period. However, it was restored within a short time. Females gained 365 g in March 2022, and males gained 450 g, which is an excellent indicator. A kilogram of weight gain costs 5.15 EFU. The pregnancy rate was 136 %, and the inter-calving period was 271-320 days, which made it possible to provide three births in two years.

In the field of agro-industry, the most attention is paid to the development of eco-friendly technologies, which allow to improve the efficiency of natural resources in sustainable agriculture, preserving the environment, as well as to obtain high-quality, environmentally friendly, and safe products. Currently, organic viticulture and biodynamic winemaking are rapidly developing and demanding areas of winemaking. In light of these factors, it makes sense to cultivate grape varieties that are resistant to cold, fungal diseases, and pests (in particular, the Charentsi variety). Under different conditions, the microbiological state, physicochemical parameters, organic acids content, and color characteristics of Charentsi grapes were examined. We studied the physicochemical parameters of wines made by using different methods. The possibility of making ecologically clean rosé wines from this grape variety was assessed, using it as a raw material.
