The return of brewer’s yeast as an ingredient in feed
In the need for a more sustainable industry, the rapid growth of the aquaculture poses a challenge to find alternative protein sources for the aquafeed sector, due to the limited supplies of fishmeal (FM).
In the present research was evaluated the effects of partial substitution of dietary FM with either fish protein hydrolysate or autolyzed dried yeast on intestinal microbiota of gilthead sea bream (Sparus aurata).
Results highlighted a positive modulation of the Brewer’s yeast autolysate inclusion to the microbiota, favoring the proliferation of some beneficial bacteria, and suggesting that this protein source could be a valid alternative to FM for aquafeed production.
