The food supply has a great influence on the development of animal husbandry. It is its basis. Health of animals, quality and quantity of the made production are dependent not only on the amount of the prepared forages, but also to a greater extent on their quality and balance. The quality of the prepared forages has an impact on their consumption and digestibility. Therefore, the more qualitative the forages are, the higher the level of the productivity of animals is. High level of the organization of the balanced diets reduces costs of forages per unit of production by 1,5-2 times in comparison with unbalanced diets. This fact once again proves the importance and necessity of biologically full-fledged diet of feeding animals. The full-fledged diet should contain the optimal quantity of digestible protein, fodder units and other nutrients. Indeed, owing to full feeding, the productivity of animals increases and the body weight increases as well that, in turn, has a positive impact on the economic condition of the subject. However, rational use of forages requires determination of their quality and energetic and protein nutritiousness. To produce optimum diets in which all above-named criteria are considered, special programs for optimization of diets can be used that allow to provide animals with forages containing all the necessary nutrients at minimum expenses. These programs are based on the methods of linear programming, which lie in finding optimum plans for the problems with linear structure. For the solution of linear programming problems the simplex method is usually used which in a general view means that with the help of a complex of consecutive procedures the solution of a problem that meets an optimality condition is found. In this article, the problem of minimizing the cost of a diet for bulls will be solved with the use of the program named Optim V 2.0

The topic of document circulation is viewed in this article and is considered significant as the success of any organization depends on the correct choice of technology. In modern conditions the work with documents should be improved to reach high management efficiency since every management decision is always based on service documents. The organization of work with documents affects the performance of the administrative staff and work culture of managers. The success of management activities in whole is largely dependent on the way of maintaining documentation. Properly organized document circulation strengthens control functions of accounting, accelerates the drawing up of accounting reports and increases the efficiency of accounting. Therefore, the accepted system of documenting should reflect the sufficiency of all the economic activities of an organization and facilitate the identification of hidden reserves. The reflection of economic activities should be based not only on their legal form, but also on their economic content and business conditions. To organize document circulation means to develop forms of primary documents, accounting registers and reporting forms other than standardized, to create a schedule of document circulation, to determine the mechanism of taking documents to accounting and to choose the system of document processing and the order of storage. The documenting of business transactions is one of the distinguishing features of accounting as it allows monitoring economic processes. Thus, the importance of the proper document circulation is obvious because it plays an important role in every company. Its improvement and proper control allow getting the necessary information to make different kinds of management decisions, but its misuse leads to financial and criminal liability
