Investigations on prophylactic effects of coarse feed structure and/or potassium diformate on the microflora in the digestive tract of weaned piglets experimentally infected with Salmonella Derby.

The purpose of this study was to examine potential prophylactic effects of a coarse feed structure and/or potassium diformate (KDF as feed additive) addition to diets on the microflora of the digestive tract in reared piglets experimentally infected with Salmonella Derby. The results show that coarse grinding as well as KDF addition are able to influence positively the intestinal flora and are capable to reduce Salmonella excretion of infected piglets. Coarse grinding of main ingredients (e.
