CON and TRT groups fecal samples were collected, stored in sealed and un-sealed containers, and sprayed with: Non-anti-microbial agent (NAMA, saline water) and anti-microbial agent (G-Fresh, 200 gm fecal sample : 1 mixed probiotic).
Means in the same row with different superscripts differ significantly.
