Association between serological salmonella monitoring in breeding herds and meat-juice prevalence in sow herds with production of finishers
Several epidemiological studies have studied risk factors for salmonella infections in finisher pigs. Most of these studies have focused on the risk for having a high prevalence, measured either bacteriologically or serologically. Surveillance programs have been implemented in several European countries, measuring the salmonella prevalence in meat-juice samples. The rationale is that herds should decrease the salmonella prevalence by instituting salmonella reducing production and management strategies, including hygiene, all in-all out production and manipulating the gut flora by the use of organic acids, fermented liquid feed and coarse ground, non-pelleted feed.
