    Examination of Salmonella Prevalence in Pigs Through Rye‐Based Feeding and Coarser Feed Structure Under Field Conditions by Jens Gerrit Lindhaus, Bernd Reckels, Bussarakam Chuppava, Richard Grone, Christian Visscher, Clara Berenike Hartung

    Published 2024-11-01
    “…Results Rye‐based diets had a significant (p < 0.05) impact on Salmonella antibody (percentage optical density [OD%]) detection. In this study, it became apparent that significantly fewer positive OD% values could be detected due to the increase in rye compared to farms that did not change the feed (Farm 6 P0: 35.45 ± 36.18; P1: 15.48 ± 16.98; P2: 9.36 ± 8.17). …”
