Intestinal microflora has a beneficial effect on the physiological and biochemical processes taking place in the digestive tract. GB animals were observed to be affected by slowed intestinal peristalsis and digestion, altered redox potential, more alkaline pH of the intestine, decreased enzyme activity for β-glucuronidase in the large intestine, and increased activity for alkaline phosphatase and disaccharidase (Berg, 1996)
