The application of potentially beneficial microorganisms to increase host defense is a new trend to increase health benefits. We developed the first specifics host probiotics for goats and pigs from a mixture of lactic acid bacteria isolated from healthy animals. In both cases, the probiotic administration enhanced the body weight and was able to modify microflora balance by reducing Enterobacteria like Salmonella/Shigella and increasing lactic acid bacteria. The intestinal composition of fatty acids was modified, with a diminution of statured fatty acid and increasing the beneficial linoleic acid.
On the goats, the probiotics administration was correlated with a ten time diminution of fecal putrescine (cancer and bacterial disease, marker) and a decrease of 60% mutagen fecal concentration, indicating the protective effect of the treatment. These results are encouraging towards the use of probiotic mixtures as functional food for goats and pigs
