PREPARATION OF POLLNORMAL MIXING MIXTURES
In this article, the authors specify the requirements for the creation of a high-quality full-fat feed mix for cattle. The data indicating compliance with these requirements of equipment manufactured by Zagromash LLC is provided. The methods of investigation are the analysis of the data of full-scale feed mixtures and their effect on the productivity of animals, as well as mechanical means (mixers) for the preparation of high-quality feed. It is proved that the degree of grinding of voluminous fodders in the composition of a homogeneously mixed diet significantly correlates with the productivity indicators of a dairy herd. To achieve the optimum moisture indicators and controlled granulometric composition of the diet can only be provided that the appropriate technological capabilities are available. These capabilities should allow easy regulation of the processes of grinding individual types of feed to the appropriate particle size, optimally mix them into a homogeneous mass, freely control the moisture content of the mixture with the optimal introduction of liquid components. To the grinding process, demands must be made taking into account the given conclusions, ie, the maximum particle sizes should not be more than 5-8 cm, and the content of fine particles should be minimal. The predominance of particles of 3 mm or less leads to a reduction in chewing activity (time spent on chewing), fat content of milk and pH in the rumen. Thus, the use of feed dispensers of the "Master" line allows to improve the quality of preparation of a full-scale feed mix, which, in turn, improves the feed intake of animals and their productivity
