The group and individual differences of the tested bulls on the main indicators of productivity were revealed. The highest rates were in group 2 among the descendants of the Journal 2101. The average live weight at the age of 15 months was 350.5 kg. The average daily increase in the group was 814.5 g. The worst indicators were for group 3, the Violent Bull 2140 – 342 kg and 777.9 g, respectively. The complex index in group 2 of the descendants of the Journal 2101 was 101.9% and was the highest in experience

The theoretical significance of the research lies in the expansion of knowledge about the effect of the feed additive “Amylocin” on the prenatal and postnatal development of lambs, on metabolic processes in the body and on the productive indicators of ewes

To date, the problem of microorganism resistance to antibiotics is one of the most important problems requiring immediate solutions in the near future. The article deals with the international experience of dealing with this problem, the introduction of evidencebased requirements for the use of antibiotics at the national and regional levels, describes the correlation between the effectiveness of the use of antibacterial drugs in veterinary medicine and animal husbandry with antibiotic resistance

The article presents some results of the work of veterinary specialists of the Budgetary Institution of the Republic of Kalmykia “Elista City Animal Disease Control Station” to prevent the occurrence and spread of infectious animal diseases in Elista and adjacent settlements. The dynamics of diagnostic studies and vaccinations against particularly dangerous infections during 2020-2022 for cattle and pets – cats and dogs is shown. It has been established that veterinary specialists of this institution carry out antiepizootic measures in accordance with the plan, while often the number of diagnostic studies and vaccinations exceeds the planned indicators.

The influence of forest belts on the yield of grain crops is undoubtedly justified, since the wind speed largely depends on the windage (or openwork) of field protection structures, hence favorable conditions for growth and development, a decrease in disease susceptibility, damage by phytophages

The article is devoted to the modern assessment of the state of land resources in the central and eastern natural and agricultural zones of Kalmykia. For four decades, the attention of accountants and practitioners has been focused on the study of the processes and sub-processes of desertification. The first systemic document with an assessment of the state of natural fodder lands, the Eastern zone, and land management activities was the “General Scheme to Combat Desertification in the Black Lands and Kizlyar Pastures” (1986).
The implementation of the activities of the “General Scheme to Combat Desertification in the Black Lands and Kizlyar Pastures” made it possible to stop the processes of desertification. Since 2000, agrophytomeliorative measures to restore and increase the productivity of pastures have been ineffective.
In this regard, it is necessary to revise the concept of combating desertification within the framework of the National Action Program to Combat Desertification. Namely, to reconsider the traditional paradigm of the perception of land as a source of food resources towards their integral part of the biosphere, which ensures the sustainable existence of man.

The article considers the nature of the biological cycle in the semi-desert zone in the south of Kalmykia. Chemical analysis of edtifier plants growing on saline and brackish soil shows that the content of ash elements and nitrogen in them is closely related to the conditions of their habitat. Black wormwood and especially prutnyak, growing on a more saline salt marsh, unlike chamomile, absorb twice as much sodium. Despite the species differences of saline vegetation, the accumulation series are close and are characterized as sodium-calcium-potassiumnitrogen for the aboveground part and as sodium-potassium-calcium-nitrogen for the roots.
