Brucellosis, a bacterial disease caused by the genus Brucella, is a zoonotic and occupational disease. A high risk of infection with Brucella is associated with the workplace. Infection may occur by inhalation, conjunctival or skin contamination, accidental injury with a syringe, or exposure in a slaughterhouse or food processing facility. This study delves into Brucellosis, a zoonotic bacterial disease caused by Brucella, focusing on occupational exposure among slaughterhouse workers and food processors in Armenia. The research assesses the knowledge, attitudes, and practices of 306 participants, including 18 slaughterhouse workers and 288 food processors (76 meat and 212 milk employees). Despite universal awareness (100 %) of Brucellosis risk, the study uncovers potential shortcomings in workplace practices, notably in the use of personal protective equipment (PPE), as 43.9 % of respondents wash their working clothes at home. The findings underscore the need for ongoing education and remediation efforts to enhance safety measures and also emphasize the imperative of addressing these issues within at-risk groups in Armenia.

Research works demonstrate a rising demand for high-quality wine in Armenia. Our objective was to produce premium red and rosé wines using the relatively unexplored grape variety “Hastakot”. Throughout the research, we utilized various winemaking technologies to produce red and rosé wines of the grape variety “Hastakot”. Simultaneously, multiple physicochemical and sensory attributes were investigated in the produced must and wine. The obtained results highlight the ability to make unique wines from the grape variety “Hastakot”, indicating a potential market impact and gaining consumer appreciation.

Potato peeling machines do not provide the necessary technological quality of the tuber cleaning process. The shovel separation system operating in heavy ground conditions must be equipped with a dynamic shredder of tubers. The driving mechanism of grinding and pipelining, operating on a dynamic principle, is located in front of the goiter of the potato peeling machine and covers the entire profile of the tuber. The ground chips cut from the tuber should be thrown into the aisle to reduce the amount of soil in the tuber-soil mass, the most purified tuber mass from the soil should be fed into the filter elevator. The analysis of the calculated value of the angle of installation of the knife shows that the optimal position of the knife in the range of rotation angles of the rotor depends only on the kinematic parameter. When justifying the parameters of a large-sized conveyor, determining the optimal value of the angle of installation of the knife is necessary, but still insufficient condition. A sufficient condition requires justification of the second parameter of the knife installation to ensure the simultaneous fulfillment of two conditions: cutting chips with an inclined slide and its ejection into the interline space. The installation condition of the knife is provided by sliding cutting, taking into account that it is necessary that the Earth chips be dumped into the aisle after cutting from the tuberous soil, to reduce the amount of soil in the tuberous-soil mass, a more purified tuberous mass from the soil is fed into the filter elevator.

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.

In livestock breeding, particularly in sheep breeding, biotechnology of industrial technology plays an important role. A remarkable characteristic of technology is that it should be economically and biologically suitable. As a result, we are faced with the task of increasing grain yields and qualitative compositions of sheep. Ewes not having enough milk to feed their lambs after birth, result in malnourished lambs that grow poorly. Consequently, they become sick, and the rate of decline increases. Based on the analysis of the data, it appears that the variation in the live mass can also be attributed to ewes feeding, care, and behavior during the manger period. According to the research program, 2.5- and 5-month-old lambs were weighed. 2.5-month-old lambs had an average live weight of 17.0-20.51 kg for males and 15.10-18.13 kg for females. Compared to the live weight of newborn lambs (3.85 kg and 3.20 kg), the absolute weight gain of male and female lambs at 2.5 months was 16.66 kg and 14.93 kg, respectively. Lambs grain weight rapidly from birth to 2.5 months old (200-220 grams per day), which is typical for lambs in this age group. The data shows that lambs up to 2.5 months of age grew more rapidly than lambs 2.5-5 months of age, which was 12.69 kg and 12.09 kg, respectively, which is typical for lambs this age of multi-purpose sheep.

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.

The article presents the results of two-year investigations related to the effect of different soil cultivation methods, application times of equal doses of mineral and organic fertilizers and bio-humus with bentonite application against their background on the dynamics of macronutrients accumulation and their removal/output through the crop yield. Considering the changes in the winter wheat growth, development, and yield capacity under the effect of different soil tillage methods, as well as the applied fertilizers and bentonite in rainfed conditions, and also the nutrition characteristics, to get high and sustainable yield the cultivation of winter wheat should be implemented only through loosening method, while fertilization should be implemented by introducing natural rock bentonite into the soil either on the background of mineral fertilizers (N60P60K60) or bio humus (3.5 t/հa) in autumn, as a result of which the soil air, nutrition and humidity regimes improve, favorable conditions are created for the regular growth and development of the plant and 48.8-52 c/ha grain and 89-96 c/ha straw yield is ensured.

The main goal of the research was to study greenhouse tomato hybrids under hydroponic greenhouse conditions and to enhance the agro economic properties of tomato hybrids, offering farmers the hybrid that ensures high efficiency of tomato cultivation under hydroponic greenhouse conditions. During the vegetation period, phenological observations, biometric measurements, and crop counting were performed.
