Our objective was to measure the effects of a Lactobacillus fermentation product (LBFP) on fecal characteristics and microbiota, immune function, and oxidative stress markers of dogs. Thirty adult dogs were used in a completely randomized design study. All dogs were fed a basal diet to maintain body weight for 5 wk and then randomly assigned to a placebo or LBFP supplement for five more weeks. Fecal and blood samples were collected after baseline and treatment phases. Change from baseline data were analyzed statistically. Most blood markers were unaltered by treatment, but LBFP-supplemented dogs had lower changes in liver enzymes and IgM than controls. Change in fecal scores tended to be lower in LBFP-supplemented dogs than controls, signifying firmer feces. Fecal bacterial alpha diversity tended to be higher in LBFP-supplemented dogs than controls. One fecal bacterial phylum and 15 bacterial genera were altered by treatments. After 5 wk, dogs underwent transport stress (45-min vehicle ride) to assess oxidative stress markers. The increase in serum superoxide dismutase after transport was greater in LBFP-supplemented dogs than controls. Our data suggest that LBFP may provide benefits to dogs by stabilizing stool quality, beneficially shifting fecal microbiota, and protecting against oxidative damage when undergoing stress.
