To study the adaptive and acclimatization capabilities of imported apple cultivars to expand the geographical boundaries of their use in the specific lowland conditions of the Ararat Valley as well as to understand their genetic resources in new growing conditions, production experiments were set up. The following encouraging data were obtained Based on a two-year study of five new novel cultivars of apple trees in three different areas. Five apple tree cultivars were investigated: Granny Smith, Jonagold Decosta, Fuji, Mutsu, and Gala. During observation and study, they showed a high yield productivity. As a result, all five imported cultivars of apple trees are recommended for growing in intensive orchards and under similar agro-climatic conditions.

A nation’s health and mental strength depend on its food consumption which is one of the main conditions for the full functioning of the human body. In modern times, the demand for sour milk products has increased significantly due to their dietary and medicinal features. The research object was pure cow’s milk, almond milk, almond flour, and samples of sour milk products. During the work, a study of the physicochemical and sensory indicators of the raw materials added almond milk, and the finished product was performed. Based on the sensory and physicochemical indicators of the product, the optimal dosages are as 70 % of cow’s milk, 30 % of almond milk, and 1.5 % of almond flour were determined. Based on the above, it is recommended to introduce the developed technology of lactic acid products in production, which will complement the assortment of sour milk products, enrich the chemical composition of the product, and increase the body’s resistance and digestibility.

The second part of the article series is about the study of the influence of yeast and autolyzed yeast derivative on red wines’ qualitative and quantitative characteristics. Wine samples in which the preparation process was explained in the first part of the article were investigated. Wine coloring and phenolic compounds were measured. Organoleptic properties of the wines are presented as spider graphs with tasting notes.

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).

The study aimed to assess 58 veterinary laboratory specialists' knowledge, attitudes, and practices concerning brucellosis across all regional (Marz) and central laboratories (Reference Laboratory for Especially Dangerous Pathogens). The survey was developed to assess the knowledge of lab specialists and identify gaps in laboratory activities that may have an impact on test results. Questions covered the following topics: a) disease epidemiology, b) sample conditions, c) biosafety and biosecurity, and d) laboratory tests, requirements, and indicators. According to the results, 45 % of respondents are 51 years old or older, most (26 respondents/45 %) have six to ten years of laboratory experience, and 20 respondents (35 %) have 21 years and more experience. Eleven people (19 %) had not received professional training. At the same time, 90 % and more correct answers were given by respondents who had passed training during the last year. In the last year, a person took training but did not answer 90% of the questions correctly. Most part (86 %) of respondents were not familiar with lab test indicators (sensitivity, specificity, accuracy, etc.) and 46 (79 %) were unaware of screening and confirmation tests requirements. Only 55 % (32 people) knew that one serological test was insufficient to make a final diagnosis, but 24 (75 %) of those respondents could not justify that. This study shows that it is necessary to review the current mechanisms for the preparation of laboratory specialists. This will indirectly impact an accurate assessment of the epidemiological situation of brucellosis in Armenia.

Using research findings, it was determined that each strain exhibits distinct morphological, biochemical, and tinctorial attributes that are intrinsic to its particular classification. Remarkably, the API test proficiently categorized the subtypes of these strains, achieving an exceptional precision rate of up to 99.8 %. The following strains of microbes have been isolated during this study: E. coli, Salmonella Typhimurium, Staphylococcus spp., and Proteus mirabilis. The results of analyses conducted through the discօ diffusion technique reveal a diverse spectrum of antibiotic resistance profiles among the multiple strains isolated from poultry, encompassing 28 antibiotics originating from Italy. The acquired data are of significant scientific and pragmatic value. This underlines the need for specific emphasis on strains manifesting pathogenic traits, particularly those demonstrating multidrug resistance involving three or more distinct antibiotics. The importance of understanding and managing antibiotic resistance in avian microbial populations is underscored by this imperative.

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.
