This study aims to develop technology and a recipe for a novel type of functional bakery product using an alternative sweetener. As licorice roots contain glycyrrhizin, they can be replaced with sugar. Compared to sucrose, glycyrrhizin has a sweet taste 50-100 times stronger. In addition to developing technology for a new product, it is also necessary to consider the economic efficiency and safety of the end product as well. According to the AST 36-94 and AST 37-94 normative documents in force on RA territory, porosity and moisture were determined as physicochemical indicators. A KERN analyzer was used to determine the moisture content of the finished product. The examination of cadmium, arsenic, mercury, and lead from safety indicators was performed according to the normative documents GOST EN 14083-2013, GOST R 51766-2001, and GOST R 53183-2008. As long as there are no risks associated with harmful effects on human life or health, food products are safe. A finished product should also be cost-effective, profitable, and economical. The safety indicators of the finished product were evaluated for their economic efficiency and compliance with the requirements of the existing normative documents. It has been proven that licorice root extract is safe to use in baking since not all sugar substitutes are safe. Despite being novel in the domestic food market, particularly the functional food market, the proposed product can stimulate the growth of bakery industry.

Scientific research was conducted from 2020 to 2022 under laboratory conditions and on cabbage plantations (plot and industrial). It has been confirmed that cabbage plantations in the Lukashin community of the Armavir region had a high population of cabbage moth caterpillars. Local bacterial cultural liquids of Bacillus thuringiensis species tested separately and in combination with sublethal doses of insecticides showed high biological effectiveness against phytophagous caterpillars of ages I-III, which does not differ significantly from the reference indicator: commercial bacterial preparation Lepidocide. According to the results of laboratory examination of the bodies of the deceased larvae, it was found out that the decomposing body tissues of the pest larvae were filled with insecticidal sporocrystalline components, which confirmed that the death of the phytophagous larvae is the result of the effect of the tested insecticides. When struggling against cabbage moth caterpillars, it is proposed to use bacterial culture fluids alone with a lethal dose of 300 million spores/ml and in combinations with their sub-lethal quantity (titer of 150 million spores/ml) with the chemical insecticide calypso (0.033 % suspension).

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 this article, we present the course and results of scientific research aimed at calculation of the concentration of somatic cells in cow's milk to detect subclinical mastitis in individual farms of the Republic of Armenia. Comparison of somatic cell concentrations in milk from healthy and sick cows with subclinical mastitis, analysis and comparison of blood morphological parameters in sick and healthy animals has been implemented and the relationship between somatic cell concentration in milk and morphological abnormalities in sick cow blood has been identified. SC concentrations between 300 and 500 thousand/ml are indicative of mastitis risk. In this case, the type of reaction manifested was positive. It was found that the viscosity of the investigated solution "Somatic plus" + milk increases in proportion to the increasing concentration of somatic cells in the milk sample, which indicates subclinical mastitis. A study of the morphological parameters of blood in healthy and subclinical mastitis animals revealed some deviations from the reference values of blood parameters, leading to the conclusion that these changes in animals' blood are related to an increase in the number of milk's somatic cells. Increased leukocytes were found in sick animals' blood. This was followedby an increase in stab neutrophils, eosinophils, monocytes, lymphocytes, and ESR. As a result of all this, the body is experiencing inflammatory processes mobilizing its defensive mechanisms against pathogens.

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.

Badalyan, M.V. | Melikyan, A.Sh. | Aloyan, T.B. | Sahakyan, A.J.
The crops variety growing in Armenia has not been fully explored yet, hence, their genetic potential has not been revealed. Therefore, study of gliadin (Gld) locus contained in cereals’ embryo will further clarify the process of allelofunds and genotypes, homozygocity and heterozigocity, genetic similarity, genetic formula and genomic analysis of studied cultivars and wild species. The research was carried out in 20212022 in the educational laboratory of Food Quality Control of the Armenian National Agrarian University. The samples of the studied plants were taken from the exsitu seed collection of the National Gene bank of Agricultural Crops and their Wild Relatives of the “Scientific Center of AgroBiotechnology” branch of the Armenian National Agrarian University. From the electrophoretic spectrum of gliadin (Gld) for the study and identification of the genetic diversity of the inventory samples of cereals diversity protein formulas were deciphered, allelotypes and genotypes, homozygosity and heterozygos ity levels were determined, and genomic analysis was performed. According to the genomic analysis of the studied cereals varieties and wild relatives using protein markers, gliadin is spread into four zones: α, β, γ and ω. The genes regulating the synthesis of different parts of gliadin of α, β, γ, ω zones, are polymorphic located in chromosomes 6B(S), 1A(S), 1B(S), 1D(S), and in the case of Alti aghaj, Voskehask and Gjulgian also in 6A chromosome. There are no genes regulating the synthesis of gliadin segments in chromosome 6D(α). Research results, as genetic markers, can be used in identification and selection of studied varieties and wild species.

Hambardzumyan, A.M.
Throughout the current research 20 rare plant species of the RA mountain meadow zone has been studied and the botanical, topographical, cartographical and graphical descriptions have been compiled based on the existing spatial database. At the first research phase, three rare plants growing in the regions of Kotayk and Gegharkunik were mapped in the ArcGIS environment: Inula acaulis Schott & Kotschy ex Boiss., Acanthus dioscoridis and Draba araratica Rupr. For mapping, first their distribution per communities, settlements, operational significance and soil type was studied and identified, then digital mapping and analysis were performed in the GIS (Geographic Information Systems) environment. Based on the results, it was recommended to take appropriate measures for their preservation. Further changes in the ecological condition of rare plants growing in the selected regions were studied, maps of the given areas were drawn up in the GIS environment, and analysis of plant location, growth density, distance from the settlement, functional significance of the land, threats of extinction as a rare plant species, and conservation measures was performed. The received digital maps and analysis of mapping results justify the need for the development of additional measures (legal, economic, environmental). In order to map the mentioned plant species in ArcGIS environment, sequence of actions has been developed based on which it is possible to update, adjust and complete the database of rare plant species in the mountain meadow zone of Armenia and enrich the global biodiversity repository through the GBIF system.

The implemented research was aimed to evaluate the biological and economic indicators of the studied varieties of zucchini, to introduce the most valuable and highyielding variety into production. Expert studies were conducted in 20212022 in the Taghavard community of the Martuni region of the Republic of Artsakh, located at an altitude of 600m above sea level. Anna (control), Adana and Zartonk zucchini varieties were studied. Each cultivar was planted in a 50 m2 plot with four replications. In each plot, 123 plants were planted in two rows of 10 m length, with 90+70 cm interrow and 45 cm interplant distance. During the vegetation period, feeding with the norm of N 45 was done twice. Breeding varieties were evaluated according to growth and development stages, duration of vegetation, resistance to diseases and pests, and yield indicators. According to research, the Adana and Zartonk have a relatively long vegetation period (72 and 73 days), and the Adana (510 cent/ha) stands out in terms of crop structural elements and yield indicators. Adana and Zartonk are relatively resistant to diseases, and the difference in pest infestation is insignificant. Adana surpassed both Anna and Zartonk in terms of fruit percentage. It exceeded the highyield control by 135 cent/ha, at the same time, with high economic efficiency, it provided 135 cent/ha crop addition and AMD 420.000 additional profit per hectare. It is recommended to cultivate the Adana zucchini variety in the submountainous zone of the Artsakh Republic.

Babakhanyan, T.O.
Milk is a good source of protein, calcium, vitamins, magnesium, casein. Its advantages are the pleasant taste, dietary features and the ability to quench thirst. However, in hygienic terms, it is not without drawbacks. In particular, milk is a beneficial environment for the development of various microorganisms, including pathogens, as a result of which it can easily become a carrier of infectious diseases. Therefore, the task was set to investigate the risks associated with the transmission of a number of dangerous zoonotic infectious diseases, in particular brucellosis and tuberculosis. To this end, organoleptic and laboratory studies were carried out on 20 samples of unpasteurized milk purchased from private individuals in different administrative districts of the city of Yerevan. Through organoleptic method the color, smell, taste, texture of milk was determined. Under laboratory conditions, pH, purity, density, total acidity, bacterial contamination of milk and the presence of brucellosis antibodies and causative agents of tuberculosis were detected. Milk samples were also examined for starch and soda content (milk adulteration).

2023
Geogulyan, V.S. | Sargsyan, M.A.
Calf coronavirus (viral diarrhea) is an endemic disease that is mainly spread by maternal infectivity, cold, wet conditions and crowded housing conditions. Feces were sampled from the rectum of 50 newborn, 3-35-day-old calves. The samples were examined by microbiological, hemagglutination and Bovine enterichek accelerated test (antibody strips) in the ANAU Research Center of Veterinary Medicine and Veterinary Sanitary Examination. Epidemiological data, manifestations of clinical symptoms, patho-anatomical changes, hemagglutination reaction and Bovine enterichek test were used to identify the infection of 3-35-day-old calves. Feces with mucus content from the rectum of calves with diarrhea (50 samples), internal organs (spleen, liver, etc.) and affected small intestines of fallen 3-7-day-old animals (3 heads) were examined.During epidemiological studies, an increase in body temperature (42 0C), anorexia, exhaustion, depression and watery-slimy diarrhea were observed in sick calves. Clots were found on the walls of the arteries of dead animals, inflammation and hemorrages were found in the lymph nods and kidneys. According to epidemiological, clinical symptoms, patho-anatomical changes, microbiological research, as well as hemagglutination reaction and Bovine enterichek rapid test data, both coronavirus and enterobacterial diseases were detected in animals at the same time. As a result, farmers and villagers suffered economic losses due to newborn calf falls. The disease was diagnosed according to hemagglutination reaction, Bovine enterichek test and microbiological methods. Morbidity and mortality rates were respectively 0.1 (10 %), 0.6 (60 %), economic loss – AMD 209 400. Based on the effectiveness of the “BolsheVac” (“БольшеВАК”) vaccine, we propose to carry out preventive vaccinations in vulnerable farms.
