Effects of Mannanoligosaccharide and sodium chlorate on growth performance of nursery pigs during and acute enteric disease challenge with Salmonella enterica serotype typhimurium
Kansas State University Swine Research. A 28-day experiment was conducted to compare the effects of feeding mannanoligosaccharides (mannan) and sodium chlorate (chlorate) to weanling pigs as a possible substitute for the commonly used antimicrobial carbadox. Pigs were fed experimental diets for 2 wk, then challenged orally with Salmonella enterica serotype typhimurium to establish enteric disease. Average daily gain and ADFI were greater for pigs fed carbadox than all other treatments in the 2 wk following infection. During the first week after infection, pigs fed chlorate had greater G/F than control pigs, and pigs fed mannan tended to have greater G/F than control pigs. There were no differences in feed efficiency among treatments during the second week following infection.
