Dietary supplementation with fermented rapeseed and seaweed modulates parasite infections and gut microbiota in outdoor pigs.

ABSTRACT: Outdoor pig production systems can increase exposure to helminth infections such as Ascaris suum. Anthelmintic drug treatments are currently the primary strategy for controlling such infections; however, this approach is considered unsustainable due to the risk of parasites developing anthelmintic resistance. This study investigated the potential anthelmintic effect of a 2% w/w fermented rapeseed-seaweed (FRS) dietary supplement administered over an 11-12 week period in growing-finisher pigs. Outcomes assessed included parasitic fecal egg counts (FEC), serology, gut microbiota composition, and systemic inflammation. The FRS supplement consisted of 6% Saccharina latissima, 6% Ascophyllum nodosum, and 88% rapeseed meal (based on dry matter) and was provided in two differ
