Presscakes as an Alternative for Prebiotics in Animal Feeds

Abstract

The article examines the influence of the oilcakes of lavender, camelina, nigella, mustard on the microbiota composition in the model of the bird's intestines. It has been shown that the cakes of mustard, camelina and lavender exhibit prebiotic activity in a model of an artificial intestinal environment inoculated with a starter from the gastrointestinal tract of chickens. Nigella cake in this model does not show activity. The activity lies in the fact that the presence of oilcake in the environment reduces the content of proteobacteria, among which there are many representatives of pathogenic microflora, and increases or does not affect the content of probiotic lacto- and bifidobacteria. The effect develops gradually and is dosedependent. It was found that the cake of the studied plants at a concentration of 1% and higher increased the pH of the medium, which may be one of the mechanisms of influence on the balance of the intestinal microbiota.
