Proportion of <i>Lactobacillus</i> species present in PM, PM-fed chickens and control chickens.

<p>The genus <i>Lactobacillus</i> was represented by only 2 species of bacteria in PM, whereas control and PM-fed chickens had a greater number of species that constitute the total population of <i>Lactobacillus</i>. PM-fed chickens had a more diverse <i>Lactobacillus</i> population than control chickens (16 species and 12 species, respectively), and the species abundance as a proportion of the total <i>Lactobacillus</i> population was also very different between the two groups.
