The article presents the results of assessing the indicators of endogenous intoxication in the process of pharmacotherapy of hepatosis in cattle. Dairy cows (n=20) diagnosed with hepatosis were treated with flavobetin, which was used daily for a month at a dose of 50 g/animal per day. In the dynamics of therapy in cows, laboratory blood tests were carried out, on the basis of which it was found that during hepatosis disturbances in protein, carbohydrate and lipid metabolism were registered and the activity of hepatoindicator enzymes also increased. With liver dystrophy in the blood of cattle a higher level of markers of endogenous intoxication represented by medium mass molecules (MMM) of the relatively healthy livestock was revealed. Course treatment with flavobetin has a pronounced positive clinical and laboratory effect in hepatobiliary disorders in cattle. In the process of recovery there was a decrease in the level of endogenous intoxication in the body of cows, which was confirmed by a lower level of MMM in the blood. Determination of these markers of endotoxicosis may have prognostic value in monitoring the dynamics of the state of the liver and evaluating the effectiveness of drug therapy for hepatopathologies in cattle.

Obtaining high-quality seed material in soil-climatic zones favorable for the production of original and elite potato seed production requires placing production on clean phytosanitary territories in the high-mountainous, North-Western and Arctic regions of the Russian Federation, where there is a minimum number of carriers of potato diseases, moderate temperatures, and a sufficient level of moisture supply to plants. The statistics of weather observations show a steady increase in average air temperatures, as well as an increase in the amount of average annual precipitation with uneven precipitation. In intensive technologies used for the production of potato seeds, there is a significant over compaction of the surface and subsurface horizons of the soil, which leads to a deterioration in the moisture supply regime for plants, which significantly affects the yield and quality of seed material. The solution of this problem requires the improvement of technological methods and technical means used during potato seed production.

The article offers a detailed analysis of the maral and deer farming in 2016-2020 by comparing the number of maral and sika deer livestock, their productivity, as well as the industry productivity. The objective of the study is to examine the current maral breeding situation in Altai Krai, and to analyse the main problems and prospects of its development. According to the production analysis of the given region’s enterprises, the shares of the maral and deer farming gross product are due to different economic and production opportunities, as well as natural, climatic, landscape and other factors. Nevertheless, this does not prevent the development of velvet antler deer farming at the foothills of Altai Krai. The study showed that maral and deer farming is not developing uniformly in Altai Krai. By 2020, the number of enterprises engaged in maral breeding has decreased from 27 to 24. The number of marals, however, increased just slightly – by 750 heads. Sika deer are still bred at 10 enterprises, but the number of livestock has decreased by 120 heads. The number of velvet antler deer in the region has increased by 2.5% over the analysed period. In 2020, the quantity of produced velvet antlers has increased that indicator in 2016 by 3,172.5 kg (8.7%), despite a decrease in the number of enterprises. The low demand for the sika deer antlers leads to the extermination of this species and smaller velvet antler yields. In 2020, 743 sika deer velvet antlers were produced, which is 340 kg fewer compared to 2016.

In the materials of the article, the theoretical question of creating sprinkler nozzles with a rotating deflector cone is considered. Mathematical dependences describing the design and technological parameters of the sprinkler nozzle are presented. The process of raindrops falling created by a rotating deflector cone is considered. The results of laboratory studies are presented, during which it was proved that the irrigation radius increased by an average of 25.2% with a rain nozzle having a rotating deflector cone compared with a smooth non-rotating deflector cone. This will allow the sprinkler nozzles to be installed on the sprinkler machine pipeline at a greater distance from each other, which will reduce the cost of the sprinkler machine.

The aim of the study was to establish the characteristics of the meat productivity of steers obtained from crossing Simmental cows with Aberdeen-Angus and Kalmyk bulls, depending on the cultivation technology. Scientific and economic experiments were conducted in three farms of the Karachay-Cherkess Republic: LLC firm Hammer (experience 1); SEC PZ Zarya -1 (experience 2) LLC Yugagrohim (experience 3) in 2021-2022. For the entire period of cultivation in crossbreeds (? Simmental + ? Aberdeen-Angus) in the first experiment, the average daily increase was 711 g, 8.5 energy feed units were spent on 1 kg of increase, while the increase in Simmental bulls was 655 g per day, 10.4 EQ was spent on 1 kg of increase, or 22.35% more. The crossbreeds (? Simmental + ? Kalmyk) were closer to the bulls of the Simmental breed in terms of growth and payment of feed. In the first, second and third experiments, the crossbreeds (? Simmental + ? Aberdeen-Angus) outperformed purebred simmentals by: pre-slaughter live weight by 29.7 (P>0.999), 12.1 and 13.9 (P>0.99) kg; the mass of the paired carcass by -18.5, 8.9 and 8.6 kg (P>0.99 – 0.999); internal fat weight by – 3.1 (P>0.999), 0.6 and 2.4 (P>0.99) kg; slaughter weight by – 21.6, 9.5 and 10.2 kg (P>0.99–0.999); slaughter yield by -1,07,0,66 and 0.49 abs.%; half-carcass weight by 9.1, 4,5. and 4.5 kg (P>0.99–0.999); muscle mass by -6.13 (P>0.999), 3.0 (P>0.95) and 3.74 (P>0.99) kg; adipose tissue by–3.75 (P>0.99), 1.91 and 0.58 kg, respectively.

The article presents the results of studying the influence of methods of basic tillage and moisture availability on the elements of the structure of the soybean crop: the mass of seeds per plant, the number of beans and seeds per plant, the height of the plant, the weight of 1000 seeds and the yield of soybeans of the Volma variety, after winter wheat. It was found that on average in 2020-2022. Moisture conditions developed in such a way that among the main tillage methods, high yield structure and yield were obtained in the variant with plowing by 22-24 cm - 2.2 t/ha, slightly less yield was obtained by non-moldboard loosening by 22-24 cm - 2 0 t/ha, disking with a processing depth of 16-18 cm produced the least amount of grain - 1.9 t/ha. In addition, it was noted that the method of basic processing affects the amount and dynamics of moisture in the soil during the growing season. During the germination period, the largest moisture reserves were recorded on non-moldboard loosening, and the smallest - on disking. In the flowering phase, when soybean plants urgently need moisture to form a crop, the largest amount of it was in plowing, and the smallest - in disking.
本文介绍了基本耕作方式和水分有效性对冬小麦后Volma品种大豆单株种子质量、单株豆数和种子数、株高、千粒重和产量等作物结构要素影响的研究结果。结果发现，平均在2020-2022年。水分条件的发展表明，在主要耕作方式中，22-24 cm - 2.2 t/ha的耕作方式产量结构和产量较高，22-24 cm - 20 t/ha的非模板松耕方式产量略低，16-18 cm的盘耕作方式产量最少，为1.9 t/ha。此外，有人指出，基本加工方法影响生长季节土壤水分的数量和动态。在萌发期间，未松动的板状土壤水分储量最大，而盘状土壤水分储量最小。在大豆植株迫切需要水分形成作物的开花期，犁耕时需水量最大，盘片时需水量最少。

The task of producing large feeds through the dissemination of modern technologies and the creation of a high-quality forage base is paramount for animal husbandry. The aim of the study is to study various biological and medical preparations and their complex use while maintaining the senate in the expanded, revealed in the film, to clarify its quality and safety. The scheme of the experiment provides for the use of benzoic acid and powdered sulfur for surface treatment in case of detection with biological preparations Biotrof and Biosil NN, as well as only with benzoic acid in searches with the preparation of haylage without preparations. For harvesting haylage, oriental goat's rue mixed with cereals is used. The laying of experimental batches of haylage is carried out under production conditions according to the generally accepted methodology of laboratory experiments. The quality of haylage was controlled by organoleptic parameters, acidity, content and ratio of acid fermentation. As a result of the research, it was found that canned haylage drugs have the best organoleptic characteristics characteristic of high-quality feed. The best effect of conservation was the combined treatment of silage powdered sulfur and lactic ferment Biosil NN. The use of these preparations increases the formation of butyric acid in the haylage, the dominance of lactic acid in the residues of acid fermentation (83.0%) has been identified, due to the fact that the feed is better acidified (pH=4.7) than haylage without consumption (pH=5, 38). According to the result of a comprehensive assessment of the quality of haylage for all assessed indicators, this feed is applied to the 1st quality class, which to the greatest extent gives an assessment of ruminant tests.

These studies were carried out in the Rostov region on the replacement and broodstock of amber trout in the second and fourth stages of maturity. The purpose of the work: to study the effect of newly developed feed additives from pond fish milt and glycerin on the performance of salmon fish. As part of achieving this goal, it is necessary to solve the following tasks: to analyze various proportions of pond fish milt and glycerin; carry out feeding of salmon fish from the second to the fourth stage of maturity; study the growth rates of fish. According to the scheme of the experiment, the first (control) group of fish received complete feed without additives. In the complete feed for the second experimental group, 2% glycerol was included by weight of the feed. The diet for trout of the third group included pond fish milt with glycerol 50 to 50% in the amount of 2.0% by weight of the feed. In the second stage of maturity, a significant increase in gross growth in the second and third groups by 13.5% and 14.4% (P<0.01) was found in relation to the control group. There was also a tendency to increase the length of the body in the experimental groups by 0.7 and 0.6 cm, respectively. The highest coefficient of fatness was in the group with 2% glycerol (6.97%). In the fourth stage of maturity, the trend towards a significant increase in gross growth continued. In the second experimental group, this indicator was higher than the control by 18.2% (P<0.01) and by 17.1% (P<0.01) in the third. The fatness coefficient in the control group was 1.74, in the second group it was significantly higher by 5.2% (P<0.01).

The purpose of the work: to study the effect of newly developed feed additives from pond fish milt and glycerin on the performance of salmon fish. As part of achieving this goal, it is necessary to solve the following tasks: to analyze various proportions of pond fish milt and glycerin; carry out feeding of salmon fish from the second to the fourth stage of maturity; study the growth rates of fish. According to the scheme of the experiment, the first (control) group of fish received complete feed without additives. In the complete feed for the second experimental group, 2% glycerol was included by weight of the feed. The diet for trout of the third group included pond fish milt with glycerol 50 to 50% in the amount of 2.0% by weight of the feed. In the second stage of maturity, a significant increase in gross growth in the second and third groups by 13.5% and 14.4% (P<0.01) was found in relation to the control group. There was also a tendency to increase the length of the body in the experimental groups by 0.7 and 0.6 cm, respectively. The highest coefficient of fatness was in the group with 2% glycerol (6.97%).

The article describes the data of scientific research on the frequency of occurrence of genotypes A1A1, A1A2, A2A2 and alleles A1 and A2 of milk protein beta-casein in cattle of various breeds, since 2014. Livestock in Pakistan, Italy, Greece, Croatia, China, Sweden, Mexico, Japan, Ukraine, Thailand, Brazil, Russia and Poland were considered. The data obtained on the territory of the Russian Federation is also described. The livestock of the Komi Republic, Bashkortostan, Stavropol and Krasnodar Territories, Arkhangelsk and Yaroslavl regions were considered. The most studied breeds in most countries are Holstein and Jaser. Holstein, Jersey, Sahiwal, white-headed Ukrainian, gray Ukrainian, hybrid (Sahiwal ? Holstein), gir, Guzera, Red, Polish, Hybrid (Holstein ? Zebu) breeds most often have the A2 allele and genotypes A1A2, A2A2. In cattle breeds in the territory of the Russian Federation, the A1 A2 genotype prevails.
