Maxi-Gen™ Plus: A nucleotide-containing product that reduces stress indicators and improves growth performance during smoltification in Atlantic salmon (Salmo salar)

Three experiments assessed the effect of the inclusion of dietary nucleotides fed as Maxi-Gen™ Plus on the stress level, growth performance and intestinal histology of in-season and off-season Atlantic salmon smolts. Increasing the dietary inclusion level of Maxi-Gen™ led to improved hypo-osmoregulatory ability and growth performance with no noted effect on the intestinal histology of Atlantic salmon. This indicates as the dietary inclusion level of Maxi-Gen™ increased from 0.05% to 0.60%, so did the “smolt window,” or period of time when the smolts can be transferred from fresh to salt water.
