The research was carried out in the administrative area of Yernjatap settlement, Aragatsotn marz, Aparan region, RA. This was at an altitude of 1850 m above sea level. Soil studies were conducted on about 1 hectare of arable land. The area is located in the steppe land zone. It was planned to investigate the shallow tillage (disking) in preventing degradation processes and increasing the efficiency of cultivated land in the investigated land area. For this purpose, field and laboratory analyses were carried out to study the soil quality characteristics. Soil sections were placed at the experimental sites. The percentage of humus content, mechanical composition, amount of water-soluble salts, soil reaction (pH), and provision of macronutrients in the soil samples were given according to the depth of each soil section. As a result of using traditional and shallow soil tillage methods, the agrophysical and agrochemical properties of the studied soils were revealed.

Latent mastitis harms the health of animals, their milk production, and the quality of milk. In cows affected by this disease sharp changes in hematological parameters, and biochemical parameters of blood and milk, which is the focus of our research. This work studies the morphological and biochemical parameters of blood and the biochemical parameters of milk in dairy cows affected by latent mastitis. The research was performed in several farms and farm households of Kotayk and Ararat regions, as well as in the ANAU Research Center of Veterinary Medicine and Veterinary Sanitary laboratories. The research outcomes prove that latent mastitis significantly impacts the composition of blood and milk components. Data obtained during the research enables a better understanding of the causes of mastitis as well as the necessity of using informative diagnostic methods in farm veterinarians’ practices.

Armenia, with its entire territory, is considered the most sensitive country to climate change. The land tax rate for agricultural lands is determined at 15 percent of the estimated net income determined by their cadastral assessment. The cadastral assessment of agricultural lands in the Republic of Armenia was carried out in 2002-2004. During the assessment, the materials of land management, soil science, geobotanical, and other studies and research conducted in the 1970-1980s were taken as a basis. The article presents the results of research and analysis conducted by the authors during 2020-2023, on the impact of climate risks on the yield and quality of crops on agricultural lands in the Republic of Armenia. As a result of the research, it turns out that among climate risks, the greatest damage to agricultural lands in the Republic of Armenia is caused by frost, hail, and drought, which affects the quantity and quality of crops from agricultural lands, and consequently the income received, which, however, does not reduce the tax burden of the landowner. As a result of the research, to modernize the assessment methodology in the process of calculating net income, it is recommended to adopt the revised calculation method developed and proposed by the authors using risk reduction coefficients (climate risks).

Honey wine, also known as a fermented beverage made from natural honey, is believed to be one of the earliest alcoholic drinks created by ancient humans thousands of years ago, long before the discovery of grape wine. Our research aims to produce wine from honey collected in the Armenian mountains. A series of articles dedicated to the study of the possibility of obtaining alcoholic beverages made by fermenting natural honey (honey wine) using different types of dry active yeast and yeast autolysis derivatives. The data obtained from the research results will be interesting from both the scientific and production points of view. This will allow us to conclude that the selected yeasts can be used for producing such alcoholic beverages.

The role of lipid peroxidation in the pathogenesis of liver diseases in sows was studied. The state of the antioxidant system in these diseases was also assessed. The liver of sows has been examined after slaughter. There were four groups formed: healthy, acute and chronic hepatosis (HS), and liver cirrhosis. An increase in the level of endogenous intoxication has established, the content of primary (diene conjugates), secondary (malondialdehyde, ketodienes, ketotrienes), and final (Schiff base) products of lipid peroxidation in the blood of sows with hepatopathy. Also noticed that sows with hepatopathy had decreased antioxidant protection, catalase activity, and concentration of tocopherol and ascorbic acid. The level of change was growing with a gravity of hepatopathy. The most expressed disturbance has been observed in sows with liver cirrhosis.

Increasing demand for semi-finished meat has led manufacturers to increase production volumes, renewing and modernizing their assortments in parallel. Technologies and recipes for semi-finished products production are known, in which animal and vegetable raw materials are combined. In addition, it contributes to the rational use of raw materials, the provision of quality food, and the improvement of technical and economic indicators. As a dietary raw material, white cabbage is an effective raw material to use in the production of semi-finished products.

In the Armavir marz of the Republic of Armenia, the effect of the load of buds was studied on the growth, yield, and quality indicators of the Nrneni grape variety. This grape variety was created at the Armenian Agricultural Institute, by crossing the 1-17-1 (Alicant Bushe x Cabernet Sauvignon) hybrid form and the Georgian Saperavi varieties. The Nrneni grape variety is lateripening, moderately high-growing, with low frost resistance and high fungal disease resistance. Experimental vineyards were planted at a planting density of 2.5x1.5 m. The vines were formed according to a low-stem multi-arm fan-shaped formation: The load of the vines was studied at 20, 30, 40, and 50 buds. Research findings related to shoot growth, ripening, and harvest quality enable us to recommend the optimal vine load for the Nrneni grape variety in the Armavir marz region. Based on these studies, we suggest maintaining a load of 30–40 buds per vine.

The ratio of stem fruit, skin, pulp, juice, and seeds is determined by mechanical analysis. A grapevine›s ratio between these components is crucial for winemaking, both in terms of yield and quality. This work aims to determine the mechanical composition of the local, less common varieties, Voskehat and Chilar. The weight of the bunch and berries, the number of berries in the bunch, as well as the weight of the seeds and the skin of the ridges are determined. The structure of the bunch, the composition of the berries, and the indicator of the composition of the bunch were calculated: For Chilar grape varieties, this indicator was higher at 1.8, while for Voskehat grape varieties, it was 1.4. Higher juice yields mean higher efficiency of wine production and lower wine costs for technical varieties.

Seven different types of grain grinders were tested under production conditions. Grain grinders with vertical and horizontal cutting organs were selected for investment in mass and feed production. Their technical, economic parameters, and operational reliability were investigated. Based on the statistical evaluation of the operational reliability of grain grinders, the average statistical values of their readiness factor were calculated, which was Kp=0.8 for UHM-2.2, and 0.51 for HHUM-2.2. Meanwhile, it is established that the readiness factor of the machines and equipment used in animal husbandry and feed production should be no less than 0.94. All defects of nodes and machine parts were identified, also scientific and practical recommendations were made to eliminate and improve operational reliability. It has been established that in the case of identifying defects arising during the long-term operation of these grain grinders, eliminating them with appropriate methods, and finally improving their structure and function, it is possible to successfully organize their mass production and implementation in agriculture, particularly feed production.

TIn the current period of agricultural management, when the task is to obtain new breeds of farm animals following modern socio-economic, regional, and natural-geographical requirements and to improve the existing ones, the problem of using the rich gene pool of wild relatives very often arises. It should be noted, however, that the genetic potential of the Armenian Mouflon was not used during the creation of agricultural animals, particularly sheep in Armenia. This was due to several biological barriers, which are currently surmountable with the use of modern biotechnological methods, especially genomic selection. To resolve the issue, we carried out the genetic passportization and barcoding of the Armenian Mouflon kept in the Yerevan Zoo according to ISSR-PCR markers. Five of the 11 ISSR primers used during molecular-genetic research had high activity: (GA)9C, (CA)9G, (CTC)6G, (GTG)6C, and (ACC)6G. A total of 63 or 71.6 % of the 88 ISSR-PCR amplicons were polymorphic. The lowest value of polymorphic DNA fragments was recorded for (ACC)6G (59.1 %) and the highest for (GTG)6C (83.3%) primers. The number of rare alleles, which indicates the originality and homogeneity of the given population, in the experimental group were: (CTC)6G and (GTG)6C. From the analysis of the material obtained during the experimental research, it was possible to decode the genetic formula and barcode of the Armenian Mouflon, which can be used as a test to clarify the identification, origin, and evolution of the species and conduct molecular selection in the breeding processes.
