Enzyme pretreatment of fibrous ingredients for carnivorous fish: Effects on nutrient utilisation and technical feed quality in rainbow trout (Oncurhynchus mykiss)

Carnivorous fish have limited ability to utilise fibrous structures as a source of energy. Treatment with exogenous enzymes targeted at degradation of non starch polysaccharides (NSP) could help to improve the nutritive value of these components. Two experiments were conducted. In the first in vitro experiment, three defatted oilseeds; soybean meal (SBM), rapeseed meal (RSM) and sunflower cake (SFC) as well as green field peas were incubated...
