The paper presents the results of studies on feeding young cattle with compound feed with 10% of granulated lupine. Its positive effect on physiological state of animals and increase in average daily weight gain by 7.81% were determined. Extra profit for the period of production inspection amounted to 21.97 rubles per animal or 1098.5 rubles for entire livestock during experiment.

The article presents the results of a study examining the influence of the duration of suckling under mothers and the level of feeding in the post-milk period of bull calves on their growth and development. The experience has shown that by increasing the level of feeding and reducing the suckling period, it is possible to significantly increase the growth rate of young animals from birth to delivery for meat

The work examines the influence of prebiotic feed additives “LaktuVet” and “LaktuSuper” on the productivity of red steppe cows, as well as on the qualitative composition of the resulting milk. Such additives, when used systemically, can not only improve productive performance, but also act as an improving agent for stimulating and enhancing the animal’s immunity. Therefore, enriching feed with additional prebiotics has important practical significance

In order to determine the effect of extruded lupine on productivity and efficiency of growing young cattle of 6- and 12-month of age, studies have been conducted helping to determine the positive effect of this high-protein feed when fed as part of a compound feed

The work studied the effect of prebiotic feed additives “LaktuVet” and “LaktuSuper” on the milk production of cows throughout the entire lactation period

The article discusses innovative methods for improving the quality and safety of milk. Modern methods of milk processing, indicators characterizing the quality of milk. Innovative ways of packaging milk

The article presents data characterizing the safety, live weight gain, and feed consumption when growing re-sex using the waste products of wax moth (galleria mellonella) larvae as a biological additive

The article presents the main data on milk productivity of Martunin type of Armenian semi-coarse wool sheep bred in the Republic of Armenia in farms of different forms of ownership.

The article describes the process of obtaining hyperimmune sera from Kalmyk cattle in the “Buddha” peasant farm in the Iki-Burul region. The peasant farm is a large modern farming enterprise that has a purebred herd of Kalmyk cattle with high productive qualities.
The Kalmyk breed of cattle is distinguished by its unique allelic composition and gene allele frequencies. The article indicates the highest frequency of occurrence of the Z antigen of the EAZ system, the A2 antigen of the EAA system, and the X2 antigen of the EAC system. The lowest frequency of occurrence are antigens U’’ of the EAS system, antigens J of the EAJ system and antigens C’’ of the EAB system.
A two-vector model has been developed that brings economic benefits. A three-time immunization schedule with an interval of 1 week and a break of 2 weeks turned out to be the most optimal and effective in obtaining hyperimmune sera

This article presents an analysis of the epizootic situation regarding bovine leukemia for the period 2020-2022. Studies have been conducted to identify the viral agent, bovine leukemia virus (BLV) using various methods, including immunodiffusion reaction (IDR), hematological analysis and enzyme-linked immunosorbent assay (ELISA).
According to the research results, a decrease in the intensity of the epizootic situation regarding bovine leukemia in the specified period was revealed. A positive reaction according to RID was shown by 0.02-0.15% of animals, which is a small proportion of the total number of those studied. However, hematological blood parameters indicated the presence of VLCR in 0.37-75.38% of animals, which indicates a significant spread of leukemic infection.
It is also noted that infestation of animals was observed in some areas, namely in Gorodovikovsky, Iki-Burulsky, Maloderbetovsky, Tselinny districts and the city of Elista. The largest number of infected animals was detected in the Gorodovikovsky district (12 animals), Iki-Burulsky district (50 animals), Tselinny district (12 animals) and the city of Elista (10 animals). The incidence rates in these areas were 4.8%, 0.09%, 0.03% and 0.67%, respectively.
Thus, the analysis indicates a decrease in the tension of the situation regarding leukemia in cattle, but there is a significant prevalence of this infection in some regions. This data is important for monitoring and taking measures to combat the spread of the disease

A noticeable decrease in the proportion of feed obtained from natural forage lands, with a progressive reduction in their area, necessitates a careful attitude towards existing pastures. At the same time, the lack of real measures aimed at improving the regime of pasture use and their increasing overload constantly threaten the degradation of pasture phytocenosis. One of the ways to prevent these processes is to organize continuous monitoring of natural ecosystems and their modern improvement and protection [2,5,7]. Many years of experience in pastoral livestock farming, which was based on the nomadic lifestyle of the population, reliably protected natural pastures from severe disruption. And even in desert and semi-desert conditions it made it possible to have a relatively stable food supply. Since during the radical and superficial improvement of natural forage lands, special requirements are placed, first of all, on the quality of processing and the properties of the root-inhabited soil layer, it is necessary to assess its physical and water-physical properties under the influence of various methods and depths of basic processing.

In the dry steppe and semi-desert zones of the Lower Volga region, under irrigated conditions, annual forage crops were studied on zonal soils of the Volgograd region, and in the dry steppe zone of the Republic of Kalmykia, a complex of problems regarding the technology of growing sorghum crops is poorly understood [1,2].
The research results confirm that when growing sorghum crops using a system of two or three harvests, the coefficient of arable land utilization increases to 1.1...1.3, it is possible to obtain 100...150 t/ha of green mass and increase the productivity of an irrigated hectare to 15 thousand feed units and more [3].
Monitoring the state of fertility of agricultural lands on the territory of the Republic of Kalmykia is carried out by the Federal State Budgetary Institution SAS “Kalmytskaya”. The content of mobile phosphorus and potassium compounds is determined by the Machigin method modified by TsINAO (GOST 26205-91), humus by the Tyurin method modified by TsINAO (GOST 26213-91), mobile sulfur by the TsINAO method (GOST 26490-85), microelements – according to approved methods [4].
