A Method for Enhancing the Efficacy of Vaccination and Reducing the Frequency of Infectious Abortion in Herd Horse Breeding

Abstract

The probiotic formulation Sakhabactisubtil based on the strains of Bacillus subtilis with zeolite can increase the immunogenicity of inactivated vaccines used to prevent rhinopneumonitis and salmonellosis abortions in herd horse breeding. By the end of the study in March, pregnant mares of the experimental group had a higher level of normal intestinal microbiota (bifidobacteria, lactic acid bacteria, enterococci, and spore aerobic bacteria) as compared with the control group. The use of probiotic preparation improves the disordered intestinal microbiota and stimulates the immunological reactivity. As a result, the efficacy of inactivated vaccines is increased by 12.1%.
