Cavitation treatment as a means of modifying the antibacterial activity of various feed additives

The quality of feed, including its microbiological characteristics, is important for the organization of full-value feeding of animals in agriculture. So, the means of non-reagent processing of feeds, including cavitation treatment, are becoming more widespread. In our study, it was shown that the amount of mesophilic aerobic and facultative anaerobic microorganisms (QMAFAnM) decreases after a 5-min treatment of the test samples (chalk, fuz, bran, and zeolite) (1.1–35 times) compared to untreated samples, while an increase in the duration of exposure is proportional to the expression of the bactericidal effect. A study of the bioluminescent response of the test strain Escherichia coli K12 TG1 under the influence of the test samples showed inhibition of bioluminescence under the action of chalk and an increase in luminescence during incubation with fusa and bran. When examining the growth rates of strains E. Coli 675 and Bifidobacterium longum B379M, it was found that water and zeolite treated with cavitation suppressed the growth of E. coli 675, while the growth of Bifidobacterium longum B379M was higher than the control values at the end of the experiment. So, cavitation processing can cause the death of microflora of feed additives, at the same time, as a result of the dissociation of a complex of organic polymers, contributing to the positive response of probiotic strains. These studies can be used in agriculture in the preparation of feed additives from waste from the processing industry.
