CIIMAR researchers show disadvantages in using glycerol in fish diets

CIIMAR Researchers found that dietary glycerol inclusion decreases growth performance and nitrogen retention efficiency in rainbow trout (Oncorhynchus mykiss). 


The study now published in Aquaculture , shows that despite increasing feed intake, dietary glycerol inclusion levels have negative effects on growth performance, rising the nitrogen excretion. In addition, dietary refined glycerol does not spare the use of proteins as a metabolic fuel, suggesting that this compound is not effectively used as an energy source.
