Research objectives to study the effect of feeding the feed additive \"Bonaka-APK\" on milk productivity and quality indicators of cow milk. Methods. The studies were carried out on two groups of dairy cows, formed by the method of pairs of analogues. Feeding ration of dairy cows of black-and-white breed with a live weight of 550.0 ± 40.0 kg and a milk yield of 16.0 ± 3.0 kg per day contained: 170 MJ OE, 1582.0 g of digestible protein and 4100.0 g of crude fiber, including 1844.0 g of starch.

The stripping of grain allows organizing the separate harvesting of grain for feed in early phases and for food purposes in the phase of full ripeness. Purpose. To carry out the economic justification of the technology of harvesting early ripening grains by stripping without threshing and the technology of preparing pelleted fish feed for fish from unthreshed ears and additives. Methods. Economical estimation of the technology of winter wheat harvesting by stripping in early phases of ripeness without threshing and its processing into feed has been carried out by comparing operational and indicated expenses of the total technological operations. Scientific novelty lies in the joint estimation of the economic efficiency of technologies of harvesting and processing of grain crops. Results. The prime cost of harvesting cereals without threshing and separation is 2.65 times lower than that of the harvesting technology with combine threshing and separation. The cost of performing operations under the traditional (from grain) and the new (from ears) technologies of pelleted fish feed production is almost equal. However, the total cost of technological operations of harvesting grain without threshing and preparation of pelleted feed from unthreshed ears using the new technology is 24.3 % lower than that of traditional technology of harvesting with threshing and preparation of feed from grain. The use of non-grain part of ears of early ripeness in the composition of feed will increase the amount of raw material from hectare of sown area by 20–30 %.

The scientific novelty lies in substantiating the rational interrelation of participants in the process of data collection and preparation under different conditions. Results. The correlation between the main monitoring tasks and machine learning models is presented. An architecture for the interaction of data preparation agents at the individual, regional, and national levels of grain production has been developed.

The creation of a unified national database is recommended, where information from regional repositories is consolidated to ensure effective monitoring of grain production and make scientifically grounded decisions regarding grain fields management. It is shown that the existence of a central database will allow for scaling of intelligent diagnostic systems and tracking phytosanitary risks in different parts of the country. A number of conceptual elements of the information support methodology for grain production management are proposed, including data collection methods, confidentiality regulations, accessibility standards, data format, quality, and security. The filling and continuous updating of the national information database require significant efforts from specialists and serve as an important element of effective monitoring and decision-making in grain production at the national level.

Determination of mobile forms of heavy metals Cd, Co, Cr, Cu, Mn, Ni, Pb, Zn in the samples was carried out by atomic absorption spectrophotometry. In the studied areas, the pollution index or concentration coefficient was taken into account, while taking into account the reference values of heavy metals. Contamination with toxic elements of soils in the reference areas was determined using the PINemerow coefficient. The pollution index of urban areas was calculated as the arithmetic or geometric mean of PINemerow for all reference areas in the city. Statistical processing of the material was carried out using the universal program Statistica 10. The scientific novelty of the work lies in the fact that for the first time data were obtained characterizing the accumulation of heavy metals in the sanitary protection zones of industrial enterprises in the city of Orenburg, and they were ranked according to the pollution index.
