Research of the work of the sieve mill of a grain-cleaning machine with a linear asynchronous drive.

This article presents the results of a study of the sieve mill of a grain cleaning machine with a drive based on a linear asynchronous motor instead of a classic mechanical drive. The purpose of this work is to describe the structural and technological parameters of a sieve mill with a linear asynchronous drive to implement a mathematical model of the technological process of a grain cleaning machine work. A kinematic study of the flat hinged mechanism of the sieve mill of a grain cleaning machine was carried out, for which all geometric dimensions are known and the laws of motion of the leading link - the electric drive of the sieve mill based on a linear asynchronous motor are determined.

The influence of "Stimix Zoostim" and "Normosil" probiotics on fecal microflora, hematologic indicators, nutrient digestibility, and growth of mother-bonded calves.

Aim: This paper presents the results of the studies on "Stimix Zoostim" and "Normosil" probiotics and their influence on fecal microflora, hematologic indicators, immunoresistance, nutrient digestibility, and growth intensity of mother-bonded calves.

Materials And Methods: The calves of the control group were fed with their basic diet (BD) without "Stimix Zoostim" or "Normosil," whereas the calves of the experimental group were fed with their BD supplemented with "Stimix Zoostim" and Normosil." For 10-20-day-old calves, the daily dose was 10 mL per head, whereas 21-90-day-old calves received 15 mL of probiotics per head per day.

Scenario Method of Strategic Planning and Forecasting the Development of the Rural Economy in Agricultural Complex.

The purpose of the study is to justify the use of the universal scenario method of strategic planning and forecasting the development of the agroindustrial complex of the regional rural economy. The scientific novelty of the study lies in the application of a set of theoretical and methodological provisions for scenario planning and forecasting the development of agriculture in the regions, taking into account the assessment of their existing potential and constructing a territorial planning scheme for the priority of participation in the implementation of strategic directions of rural development in agricultural production. The paper presents a territorial model of the priority of participation of the municipal regions of the Republic of Bashkortostan in the implementation of strategic areas in the areas of development of production of grain crops, sugar beet, and oilseeds.

Ways to reduce anti-nutritional substances in winter rye grain.

The purpose of this research was to establish the nature and extent of the influence of microwaves and extrusion on the content of anti-nutritional substances of winter rye grain. There was performed two-factor laboratory experiment with the treatment of winter rye grain by electromagnetic waves of super-high frequency (microwave) on a LG MS-2042G installation and one-factor laboratory experiment with grain treatment using a MKP-30-500 extruder. Depending on the power and duration of the microwave treatment, the content of water-soluble pentosans decreased by 0.
