- Predigetsed protein in feed may help improve salmon health says NIFES. A recent study by the organisation shows that salmon that are fed moderate amounts of predigested fish protein have lower levels of intestinal fat, and that this may have positive effects on their health. For the study groups of salmon were fed diets containing 20 percent fish meal in their feed and the rest of the protein arrived from plant protein., The fishmeal was replaced with 5 to 20 percent predigested (hydrolyzed) fish protein. “This had no effect on feed intake, but growth reduced as the amount of predigested protein increased,” says NIFES research scientist Marit Espe.

- Another NIFES story caught my attention today - research has shown that zebrafish feed needs to be standardised to produce good medical and nutritional research results. “If zebrafish are to be a good research model, and if we
want to compare the results, we will have to develop a standard
diet for these fish,” says NIFES Mari Moren, head of
research. Zebrafish fans should look out for the January/February 2013 issue of International Aquafeed in which editor Prof Simon J Davies will report on diets for the species. Read more...
