Thermomechanical processing of components of combined feeds by the expansion method
Keywords:feed industry, combined feeds, extrusion, expansion, exhibit
The availability of high-quality combined feed largely determines the level of economic development in animal husbandry and poultry farming since, in the structure of the cost of livestock products, feed costs reach 65 – 70%. At the same time, the authors of this article aim to compare the current situation around the feed industry in the Republic of Kazakhstan with a similar situation in the Russian Federation, as the formation of this industry in our countries has common roots. Thermomechanical processing methods are proposed to implement deep physicochemical changes in the protein-carbohydrate complex of components of combined feeds. As a result, the quality of the combined feeds improves. Starch gelatinization occurs, and starch grains transition into a more digestible form, contributing to its better assimilation. Bacterial contamination decreases, and coliform bacteria, colon bacillus, mould fungi, and salmonella are destroyed.
