Replacement of fish oil with Schizochytrium-derived DHA-MAGs on the growth performance, lipid composition, and intestinal microbiota Pacific white shrimp (Litopenaeus vannamei)

The intestinal tract of aquatic animals is a key place to trillions of microbial cells regarded as gut microbiota to absorb nutrients, balance immune response and maintain homeostasis. Additionally, the intestinal microbial community and abundance are affected by the aquafeed composition, as it can metabolize the ingested nutrients into microbial biomass and some healthy substances to decrease the risk of disease. Based on the above background, the experiment was performed to investigate the influences of DHA-MAGs on the lipidic species and intestinal microbiota of shrimp were revealed.
