Effects of plant-derived protein and rapeseed oil on growth performance and gut microbiomes in rainbow trout.

ABSTRACT:

Background

Rainbow trout (Oncorhynchus mykiss) is becoming popular with the increased demand for fish protein. However, the limited resources and expense of fish meal and oil have become restrictive factors for the development of the rainbow trout related industry. To solve this problem, plant-derived proteins and vegetable oils have been developed as alternative resources. The present study focuses on evaluating the effects of two experimental diets, FMR (fish meal replaced with plant-derived protein) and FOR (fish oil replaced with rapeseed oil), through the alteration of the gut microbiota in triploid rainbow trout. The commercial diet was used in the control group (FOM).

Results

Amplicon sequencing of the 16S and 18S rRNA genes was used to assess the changes in gut bacte
