Coli-induced scours is fierce intestinal inflammation. The symptoms of coli scours are seen in the piglets in the first days after birth where they can get white-yellowish diarrhoea. They quickly dehydrate and up to 50% of the litter may die in a matter of a few days.
3-week diarrhoea: The suckling pigs can get coli scours again in their third week of life. The diarrhoea is grey-whitish with a pasty texture. The mortality rate is now lower than for coli scours in newborn pigs, at less than 20%. Untreated pigs become emaciated, have coarse hair and lose body condition.
