Feeding young animals is a very important stage during their growing-up period, but in order to provide them with essential nutrients, they are fed with liquid feeds, whole milk substitute in particular (WMS). The technique for reconstituting WMS consists of dissolving it in water followed by mixing, but it is significant to follow the cooking recipe strictly, so it is necessary to develop a system with a feeding (dosing) device that will make it possible to solve this problem. Theoretical and experimental studies of the feeding device have been conducted in order to optimize the technological process of mixing liquid feed. Theoretically, the quality of determining the mixture during dosing was established for the purpose of further research. The influence of the design and technological parameters of the feeding device was experimentally studied, and its efficiency was evaluated. It was found that as the inclination angle α increases from 67,50 to 700, the rotation speed n being from 850 to 1500 minE−1, the maximum probability of staying in the tolerance field ΔP=96% is reached, and feed discharge Q ranges from 540 to 660 kg hE−1. The research makes it possible to develop a feeding device at the design stage, meeting the requirements of the recipe, having high discharge rates and the lowest energy consumption.

One of the mechanisms for enhancing innovative processes in the industry is the application of the concept of the “four-link spiral”. In contrast to the 3-link spiral, this model as one of the most important components includes a “society”, acting as one of the actors of innovative transformations. Firstly, it is society that is the main consumer of innovative products being created and, thereby, establishes “requirements”, forming demands for the quality and parameters of future products; secondly, society, in turn, acts as the initiator and generator of innovations, forming the so-called “social capital” necessary for the implementation of directly innovative transformations. In this scientific work, the problems of the formation of a “smart specialization” strategy for the innovative development of the industrial sector of the national economic system based on the application of the four-link spiral concept are investigated. A system of quantitative indicators for assessing the innovative level of industrial development is presented. The experience of introducing the concept of a four-link spiral as a mechanism of innovative development of industry (on the example of the Republic of Belarus and the Russian Federation) is given. The aim of the article is to describe innovation processes in the Russian Federation and the Republic of Belarus and to develop an innovation transfer model.

This study aimed to identify the most characteristic trends in the area of fodder production and the use of fodder as factors in the development of animal husbandry in Ukraine under conditions of war as the modern challenge for these industries. Russian military aggression is a powerful challenge for the economy of Ukraine, including its fodder production, as well as other countries of the world, reflecting on the aggravation of global problems of food shortages and food security. The effect of the mentioned challenge in Ukraine is superimposed on the identified negative trends and situation, which were formed before the beginning of 2022. Calculations based on them show that the occupation of large areas of Ukraine by Russian aggressors and hostilities caused a significant decrease in the production of livestock products due to a 13–17% decrease in the number of animals. Accordingly, consumption of fodder at the expense of these regions decreased by 16%. However, the situation is very dynamic as the war continues. Given the limitations of state support for the industry, until the end of the war the main efforts to improve fodder production in Ukraine should objectively be related to the maximum optimization of the structure of fodder rations by increasing the share of less energy-intensive forages. Every challenge creates new opportunities, therefore the post-war development of fodder production and use in Ukraine will become highly innovative.
