Technical Abstract: Experiments were conducted to evaluate the effects of different types of competitive exclusion (CE) cultures on the concentration of cecal propionic acid in 3-day-old broiler chicks, and the correlation between cecal propionic acid concentration and protection against cecal Salmonella colonization. CE-cultures developed by continuous-flow culture and an undefined CE-culture increased (P<0.05) cecal propionic acid concentrations in 3-day-old chicks and decreased (P<0.05) cecal Salmonella colonization in 10-day-old chicks compared to the untreated controls. CE- cultures that did not increase (P<0.05)cecal propionic acid concentrations in 3-day-old chicks did not (P<0.05) protect against cecal Salmonella colonization in 10-day-old chicks compared to untreated controls. A significant (P<0.05) correlation (-.88) was found between cecal propionic acid concentration in 3-day-old chicks and cecal Salmonella colonization in 10-day-old chicks.
