Researchers at Nutriad have written an article on how adding lyso-phospholipids and bile salts to aquaculture feeds can improve the absorption efficiency of major nutrients, particularly lipids, by fish.
"A wide variety of concepts and products are being investigated for improving digestion and feed utilization in livestock species. The feeding biology, digestive physiology and nutritional requirements of livestock species differ from those of aquaculture organisms. Therefore, the direct application of digestibility enhancers in aquaculture requires prior empiric screening with the aim of identifying effective compounds for the different aquaculture species. Furthermore, a key consideration is that these compounds must be heat-stable to facilitate the application in the mixer under practical processing conditions applied in aquafeed manufacturing.
The present article describes different digestibility enhancers and illustrates the potential of their application in aquafeed to reduce cost while optimizing digestive potential and growth performance."
