Atlantic salmon gut microbiome after nutritional programming across development
In this study, we investigated the impact of NP with a plant-based (V) diet at first feeding in Atlantic salmon on gut microbial composition, diversity, and microbial community functions, compared to fish fed a traditional marine-based (M) diet. We fed the fish for a brief period of two weeks at first feeding with either a V or M diet (stimulus phase), then with a M diet for 14 weeks (intermediate phase) before challenging with a V diet (challenge phase). We used 16S rRNA gene microbial analysis to monitor the composition of the gut microbiome.
