The liquid mineral- and probiotic-containing feed additives for poultry

Abstract

In this study, we assessed the biocompatibility of five probiotic lactobacilli strains and characterized sapropel, bentonite, and zeolite from the deposits of Tatarstan Republic in terms of their chemical and mineral compositions, cation exchange capacities, sorption activity, and the structure of the ion exchange and sorption complexes. We also constructed a synbiotic preparation with sapropel, bentonite, and zeolite as carrier matrixes for probiotic lactobacilli and determined their viability in the preparation for two weeks. High ion-exchange and sorption properties of sapropel, bentonite, and zeolite and suitable bacterial survival rate during storage are among the main benefits of the developed poultry feed. The obtained data have a great potential for practical use in the construction of multi-strain liquid probiotics, in which probiotic lactobacilli are immobilized on mixtures of various mineral matrix carriers.
