Issues of feed industry in the regions of Kazakhstan have been revealed. The measures of public support of field forage crops are shown. The optimal parameters of their production and processing are proposed as the basis for constructing economic models, taking into account the livestock population. The authors note that fodder production is characterized by the use of mechanized methods of crop growing for fattening livestock, efficient technologies of feed preparing and storing, which make it possible to significantly increase their cultivation and improve quality. Full value feeding is a necessary condition for the intensive use of animals and the fullest realization of their genetic potential. The conclusion is made on the need to improve government support measures in the areas of agricultural production and processing based on ecological models of cultivation of forage crops for natural climatic zones and resource rationing. To solve this problem, the analysis of cultivation of forage crops in the regions of the republic and constraining factors, environmental monitoring were conducted, assessment of the state of natural and sown forage lands was done. Technological charts of cultivation of agricultural fodder crops were developed. The necessity of the development of innovative technologies of production and processing of feed by region, models of their application for various types of farm animals has been justified. Recommendations to improve the economic efficiency of the use of feed crops in the country were done.
