FELIX, Ananda Portella et al. Digestibility and fecal characteristics of dogs fed with Bacillus subtilis in diet. Cienc. Rural [online]. 2010, vol.40, n.10, pp.2169-2173.  Epub Oct 22, 2010. ISSN 0103-8478.

Considering the benefice demonstrated by the modulating action of probiotics on the host intestinal microbiota, this study aimed to evaluate diet digestibility and fecal characteristics of dogs fed with diets supplemented with Bacillus subtilis (C-3102). Twelve young Beagle dogs were distributed in a completely randomized experimental design consisting of two treatments: diet with no addition or with the addition of 0.01% Bacillus subtilis (C-3102). Dogs passed through 25 days of adaptation to the diets, and five days of total feces collection. The following fecal characteristics were evaluated: pH, fecal score (1 - watery feces; 5: dry and hard feces), and ammonia content. Diet mean digestibility was compared by the Tukey test, and fecal characteristics by the Tukey-Kramer test. Diet digestibility was not different between treatments, but dogs supplemented with the tested probiotic presented dryer feces (39.1% vs. 36.5% dry matter), higher fecal score (3.4 vs. 3.0) and lower fecal ammonia content (0.45% vs. 0.56%), than dogs fed with the control diet. The dietary supplementation with Bacillus subtilis (C-3102) improves fecal texture and odor in dogs.
