Determination of microorganisms in dog feces. (A) Shannon index of biodiversity (H′) and (B) evenness (J′) calculated on the microbial genera measured in the feces of dogs fed a control diet (CD), rice based diet (B1) or potato based diet (B2), at the beginning of the study (sampling time T0) and after 15 d of administration of the diets (sampling time T15). Green dots denotes dogs, red line the median and the red cross the mean for each group. Legend of x-axis: B1_0, raw meat with a complementary food made of rice as the main source of starch at T0; B1_15, raw meat with a complementary food made of rice as the main source of starch at T15; B2_0, raw meat with a complementary food made of potato as the main source of starch at T0; B2_15, raw meat with a complementary food made of potato as the main source of starch at T15; CD_0, raw meat with a complementary food made of pasta and rice as the main source of starch at T0; CD_15, raw meat with a complementary food made of pasta and rice as the main source of starch at T15. ∗, P < 0.05; ∗∗, P < 0.01.
