Abstract
This paper presents research on evaluating the effectiveness of the technology of cavitation treatment of sunflower oil sludge intended for feeding ruminants. The evaluation on a general microbial content has been introduced, namely, quantitative and qualitative indicators of sunflower sludge before and after the cavitational processing have been described. During the experimental studies, the fact of a significant increase in digestibility of sunflower sludge after the cavitational processing by 21.1 % was revealed. At the same time, cavitation was not accompanied by any significant changes in the fatty acid composition of the feed, but it increased digestibility of a dry-matter in vitro due to an increase in bioavailability of the linoleic acid to 86.2 % versus 45.9 % in the native feed. The digestibility of other fatty acids either changed slightly, or decreased. The experiment shows the bactericidal and mycocidal effect caused by the cavitational processing. The effect caused by the cumulative jets of liquid when the cavitational microbubbles collapse caused the death of all microflora inherent to these types of products.
