This article presents an experiment carried out on broilers of Arbor Acres cross in an industrial poultry farm. For the experiment, the authors divided the broiler birds into three groups. Poultry of the control group received basic ration; poultry of the 1st experimental group received feed additive at a dose of 1269 g/t feed 5 days before slaughter; poultry of the 2nd experimental group received feed additive at a dose of 1693 g/t feed 5 days before slaughter. Broilers were slaughtered on day 38 of rearing. The following types of defects were recorded during slaughtering: dermatitis, cellulitis; back scratches; splinter hemorrhages, bruises, hematomas, bruises; dislocations, closed and open fractures; poor bleeding; skin tears; under-plucking; the presence of internal organs; over-steaming of the carcass. The authors applied the Ishikawa method, Pareto charts, ABC analysis, and cluster analysis to assess the quality of broiler chicken carcasses. Based on the results of these studies, the authors identified 41.7 % of defects that reduce the quality of poultry carcasses and 58.3 % of critical defects that lead to meat culling. Using clustering methods and ABC analysis, the authors identified the most important category of critical defect, D2C. This defect in poultry occurs during the rearing and processing phase. The application of the stress-corrector reduced the number of D2C defects in the 1st experimental group by 33.3 %; in the 2nd experimental group by 18.2; D2GD in the 2nd experimental group by 22.2 %. Thus, the use of statistical evaluation methods increases the efficiency of industrial control over the quality level of broiler chicken carcasses.

The authors reviewed scientific and regulatory documents on the prevention and control of bovine leukemia. Bovine leukemia is an infectious disease of tumor nature with a chronic course, the main sign of which is the malignant overgrowth of cells of the hematopoietic organs with disruption of their maturation. Such overgrowth eventually leads to diffuse infiltration of the organs by these cells or the development of a tumor. The disease is asymptomatic in 70 % of infected animals, causing persistent lymphocytosis and lymphosarcoma in 30 and 5 % of infected animals, respectively. Infections caused by retroviruses share some common features: long incubation period, latent or chronic course, strictly limited range of susceptible animals, and long persistence of the virus in the body. The virus persists in the body throughout the life of an animal.

The article considers the age-related dynamics of protein fractions concentration in the blood serum of parent birds. The obtained data make it possible to establish the main age-related changes in protein profile and synthesis of immunoglobulins, which allows for marking the main critical periods of poultry ontogenesis.

The article notes the main results of the research work of the Oirot zonal experimental station (now Gorno-Altaisk Research Institute of Agriculture) on the improvement of local cattle based on hybridization with yak. The author presented the main conclusions of the results of the hybridization of yak with cattle: hybrids of the first generation possess heterosis in live weight, meat content, milk fat, which is significantly higher than in the original animals; yak hybrids sufficiently retain the high ability to pasture during the winter, foraging from under the snow. Shorthorn hybrid animals had higher growth vigor in all rearing periods compared to Siberian Simmental hybrids and purebred yaks. The live weight of the hybrid animals averaged 140 kg compared to 68.3 kg for yaks of the same age, indicating that the smallness of the yak could be eliminated. The increased hemoglobin in the blood of the hybrid animals indicated a more intensive metabolism, and more vigorous growth of the organism, which serves as one of the indicators of the high qualities of endurance and adaptability of hybrids.

The authors cited the results of comprehensive experiments on the application of innovative environmentally acceptable growth regulators on industrial crops: potatoes and soybeans. The experiments were conducted in 2019-2021 in the soil and climatic zone of the drained forest-steppe in the conditions of chernozem on potato varieties, Lyubava (early) and Tuleevsky (medium maturing), and soybean on grain Zolotistaya (early maturing).  These experimental fields belong to the Educational and Experimental Farm “Praktik” of Novosibirsk Region and the Closed Joint-Stock Company Livestock Breeding Farming “Irmen” of Novosibirsk Region. The maximum photosynthetic performance of Novosil and Ecofus applied to potatoes and soybeans is up to 19 % compared to control. The authors of the study treated crops before sowing as well as on the shoots before the beginning of the phase of budding. The yield against the growth regulators used increased significantly by 21-24 % when Novosil and Ecofus were applied during seed treatment and when spraying vegetative plants before the phase of budding. It was statistically established that the potato yield depended on variety by 30 %, on growth regulators by 33, and on conditions of the year by 23 %.

Despite the technical diversity of techniques for winter feeding of wild ungulates, technologies for opening up forage fields during abnormal periods of the wintering cycle have serious biological potential. In winter, when high snow cover blocks access of ungulates to natural forage in form of fallen leaves and grass rags under snow, clearing biotechnical fields before vegetation becomes exposed is an efficient method of feeding the wintering fauna, especially for Siberian roe deer. By clearing snow from “winter pastures”, where biotech crops and grasses such as sunflowers, oats, peas, and alfalfa were sown, large roe deer groups can be provided with a good and balanced forage ration. Taken together, these biotechnical measures compensate for the lowering of the level of forage resources during winter anomalies and encourage the dynamics of roe deer population growth and the process of reproduction in this species.

In the article experience of application of various organomineral growth stimulants on potatoes in the conditions of forest-steppe of Western Siberia is stated. In the course of work, the authors used new perspective preparations whose application has an essential influence on growth, development, the structure of a crop, and potato productivity. As a result of work, it has been established, that organomineral growth stimulants slightly influence the duration of the vegetation period of potatoes (1-3 days). The authors found that the infestation and spread of diseases in potato crops depended to a greater extent on the conditions of the year and the preparations used, and to a lesser extent on the variety. On average, the overall degree of plant infestation on the treated background was 2-8 % lower compared to the control. The use of organomineral growth regulators has a positive effect on potato yields. The Epin-Extra preparation was the most effective, application of which provided up to 8.3 t/ha yield increase at tubers treatment, and up to 7.2 t/ha at vegetative plants treatment. The use of organomineral growth regulators does not have a significant impact on quality indicators of potatoes, as the difference between the variants was not more than 1 %.

The active development and intensification of animal husbandry, with technological errors (abnormal operation, unbalanced diets, keeping conditions, and others), increases the risk of the occurrence of a variety of metabolic diseases (ketosis, osteodystrophy, hepatosis). The study aimed to investigate the metabolic changes in dairy cows during the “close to calving” period of acetonemia. The authors researched cows of black-motley breed based on the joint-stock company of educational and experimental farm “Prigorodnoye”, Barnaul. The research was carried out four times: 2 and 1 month before calving, and 10 days and 1 month after calving. During the study, clinical and biochemical examination of the selected animals was carried out. The authors found that in ketosis cows have increased respiratory rate and heart rate. The authors also noted signs of osteodystrophy and rumen hypotonia. In cows with ketosis, the level of total calcium was below the physiological limits during the whole study. The authors observed an increase in total calcium concentration one month and ten days after calving, after which this concentration decreased. Inorganic phosphorus concentrations decreased one month before calving and increased sharply after calving. Hypoglycemia and acidosis were also noted by the authors. Acetone bodies decreased by calving and increased after calving. Triglyceride levels increased before calving and exceeded physiological values one month before calving. After calving, triglyceride concentration decreased sharply. The concentration of cholesterol in the blood of cows rose during the whole period of the study and its level was within the physiological norm.

This article presents data on the effect of the probiotic preparation Vetom 1 based on the spore-forming bacteria strain Bacillus subtilis DSM 32424. The authors also presented the combined effect of Vetom 1 and a 10 % enrofloxacin solution on the growth rate of geese. Throughout the experiment, the geese were kept in floor cages on deep, non-replaceable bedding. The authors formed three experimental and control groups of 10 goslings each according to the principle of peer pairing. The goslings of the experimental groups were given the probiotic Vetom 1; Vetom 1 in combination with enrofloxacin with subsequent replacement by the probiotic Vetom 1. Geese of the control group were not given the drug. The authors observed an increase in the absolute weight and average daily gain of the experimental geese under the effect of the studied preparations. The authors found a pronounced mass gain when applying Vetom 1 at a dose of 50 mg/kg body weight once a day for 30 days. When using Vetom 1, a pronounced average daily gain in goslings was observed both on day 15 and during the period of the drugs after action (day 30-60). The preparations in the studied doses have no toxic effect on the body of geese.

The article provides a theoretical analysis of the launch of a prospective investment cycle “Greater Siberia” in the Russian Federation. The study is based primarily on the growing debate in addressing the issue of creating new scientific, industrial, and economic centers in Siberia, which should serve new cities with a population of 300 thousand to one million inhabitants. In other words, these are distinctive clusters with developed infrastructure, research centers, and breakthrough technologies, not only in the extractive industries but primarily in the processing industries.

The article presents an approach to the organization and management of the crop production process based on digitalization in an operating enterprise. The authors have given the basic components of the system of eight components, which are sufficient to fully organize and control the enterprises with an area of 10-15 thousand hectares. The authors also considered the structure of interaction of the eight components by process participants during the season and among themselves. The main achievements from the introduction of such a product, which exceeds the average indicators for this area by 2-10 times for certain criteria and allows increasing the efficiency of production by 1.5-2 times, are considered.  A special feature of efficient production is the unique combination of technical means, the system of data accumulation, processing, and use, the high speed of decision-making on their basis, and the original author’s methods of forecasting pests and crop varieties. A single control center allows maximizing the potential of each resource (reduce component rates, increase the coefficient of soil moisture use, etc.), annually achieving the planned gross crop yield estimates at a given cost. The authors found that synergies between economics and technology must start with planning. The authors also presented a graphical representation of the process of working out the information to achieve the targets.
