Studies were conducted on the effect of extrudates on the microbiome of the broiler’s cecum. It was found that the addition of extruded feed to the diet stimulates the growth of representatives of obligate microflora, namely, bacteria of the genus Lactobacillus, Enterococcus and bifidobacterias. A significant presence of representatives of pathogenic and conditionally pathogenic microflora was also recorded. The possible lower content of non-starchy polysaccharides in the extrudate-receiving groups could serve as a key factor stimulating the reproduction of bacteria with amylolytic properties.
