Experiments were conducted to evaluate the effects of different 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 againstSalmonellacolonization. CE cultures that significantly (P<0.05) increased cecal propionic acid in 3-day-old chicks decreased (P<0.05) cecalSalmonellacolonization in 10-day-old chicks compared with the untreated controls. CE cultures that failed to significantly (P>0.05) increase cecal propionic acid concentrations in 3-day-old chicks failed to protect (P>0.05) against cecalSalmonellacolonization in 10-day-old chicks compared with untreated controls. A significant (P<.05) correlation (−.88) was found between cecal propionic acid concentration in 3-day-old chicks and cecalSalmonellacolonization in 10-day-old chicks. |
