Feed production, feeding of animals and poultry is an integral part of animal husbandry and poultry farming. Proper feeding of animals and poultry, which implies the making of an optimal diet with the input of useful premixes and vitamins, can increase their productivity. In Russia the predominant type of feeding is complete feed, which includes compound feed. Regardless of the type of feed in the process of its production, it is necessary to observe the proportions of its components. Dispensers are used for dosing, which depending on the purpose, are divided into mass and volume. We have made an attempt to generalize, systematize and implement the accumulated experience in the form of a scheme that allows us to understand the principle of operation of modern systems for dosing feed components, in which augers are used as feeding mechanisms. The purpose of the research was to build a scheme for selecting parameters and develop a methodology for studying the dosage system of feed components based on it. The results of the analysis of intellectual property protection documents and scientifi c works in the fi eld of dosing have been used to make a scheme for selecting parameters of the feed components dosing system. The results of observations on the operation of the developed system under production conditions and design features have been also taken into account. As a result of the research developed the scheme of selection of the operating parameters of the dosing system, revealed its shortcomings in the form of lower dosing accuracy with the decrease in the mass of the weighed components and the long search settings when composing the new diet. The methods have been developed to address the identifi ed defi ciencies in the determination of limit values of technological parameters.

The article presents an approach to the formation of a decision support system in the management of energy consumption of production technological systems. Such systems allow the company to detect and respond in a timely manner to the appearance of hidden energy losses, to carry out organizational measures aimed at energy saving and to optimize the timing and scope of repair and restoration work. The approach is based on the modeling of stationary sections of energy consumption, presented in the form of precedents, their accumulation and subsequent analysis in the space of influential technological parameters. In addition to the base of precedents, the system includes software modules for assessment and formation of the profile of hidden energy losses, modules of technical condition, forecast and formation of precedents. The analysis of precedents consists in the selection of similar cases of energy consumption, the formation of efficient energy consumption functions and the calculation of energy losses with its help. Hidden energy losses can be calculated in real time for all technological systems of the enterprise. This allows you to build a profile of energy losses of the enterprise. The advantage of this approach in comparison with the known ones is that it allows to adapt to technological systems with different energy sources. The article emphasizes that the method can work with the energy manager with both linear and nonlinear dependence of energy consumption on process parameters. However, the limitations of this approach are noted. Thus, the determination of latent energy losses and technical condition of the equipment requires the participation of qualified specialists of the enterprise, who must be able to analyze the results and propose measures to eliminate energy losses.

Relevance. An analysis of the development of feed production in the Stavropol Territory shows that at present, due to the low productivity of natural forage lands, the level of feed production does not meet the requirements for the development of animal husbandry. Illiterate anthropogenic influence in the dry-steppe regions of the region, where about 70% of the number of sheep and 30% of the number of beef cattle are located, led to the fact that up to 300 thousand hectares of hayfields and pastures were subjected to erosion and deflation. However, in recent years, the process of improving forage land has been reduced to a minimum. Therefore, the process of restoring the forage productivity of hayfields and pastures should be given close attention. To this end, in the zone of dry steppes we conducted research on the selection of perennial legumes and grasses of a new generation to create highly productive grassland agrophytocenoses of long-term use.Methods. The experiments were carried out in the conditions of arid and extremely arid zones of the Stavropol Territory. The objects of research were perennial legumes and cereals and their herb mixtures. Restoration of degraded hayfields and pastures was carried out by means of amelioration and superficial improvement.Results. According to our research, by enriching the degenerated grass with valuable legumes and cereals in terms of forage it is possible to significantly increase its productivity and quality. In extremely arid and arid zones the most effective mixtureswere ones involving 4 and 5 components, which yield reached 15.3–23.8 t/ha of green mass, and the yield of feed units per 1 ha was 1.9–2.6 t/ha. The increase in the productivity of the improved herbage had a positive effect on the feed capacity of the land, which increased to 0.83–1.30 conventional heads per 1 ha.

AbstractThere are the various types of heat exchangers. The selection of the heat exchanger right type is the first basic assumption for its optimal operation. The heat exchanger calculation itself is another prerequisite for its optimal operation. This article deals with the variables which are usually used to describe the stationary operation of any recuperative heat exchanger with two incoming and two outgoing streams. The knowledge of these variables, including the facts resulting from them, is necessary not only from the point of view of the calculation but also from the point of view of the evaluation of the experimental data of any heat exchanger. The variables values needed for the calculation of heat exchangers, so-called key variables, must always fall within the values range determined on the basis of generally valid knowledge about heat exchangers. The article also deals with the determination of the limit values defining the values range of these key variables.

Purpose. Development of animal husbandry is dependent on quality feed production. The activity of the field feed production as a synthetic industry is associated with the preparation of feed, their long-term storage due to the preservatives, appropriate packaging. The article discusses the optimal models for the production, harvesting, storage of forages, taking into account the peculiarities of technological parameters, production technologies of harvesting and storage. The role of feed production optimization for agricultural enterprises, aimed at meeting the needs of the commercial animal husbandry using elements of simulation is clarified and effectiveness of commercial feed production formation as a synthetic industry is revealed. Methods. In the process of the research, the following methods were used: theoretical generalization, economic model and analysis of absolute, relative and average values. Theoretical generalization – to determine the importance of the development of the feed market and commercial feed production. Economic model – to reveal the interdependence and connection between various economic phenomena and processes in production and storage of various types of feeds. Analysis of absolute, relative and average values – for the technical and economic characteristics of storage types of silage and haylage. Results. The real development of fodder production is seen in the transformation of cultivated crop products, in particular grain, into finished livestock products. It is possible, due to cross-sectoral integration, to sell not only raw materials, ready-made high-quality feed to the market to meet the needs of live-stock production. Conclusions. A special place in the implementation of the innovative policy of the field feed production belongs to the transfer of innovations in the "field-storage-feeder" system, which will act as one of the effective tools for ensuring the increase in production of high-quality feed. It was found that there are no narrowly targeted government programs for the development of fodder production as a synthetic industry.
