A full factorial design to investigate interactions of variable essential amino acids, trace minerals and vitamins on Atlantic salmon smoltification and post transfer performance
To contribute in knowledge for the development of safe, efficient and sustainable functional salmon diets, we ran a feeding trial applying a 23 full factorial design to investigate combined effects, on Atlantic salmon smoltification and post transfer performance, of variable supplementation levels o...
