Digestibility of low-cost ingredients in pelleted feed by grass carp (Ctenopharyngodon idella C. et V.)

The digestion coefficients of nutrients in 37% protein MARDI feed as well as in napier and carpet grass meals were evaluated in grass carp. Cr2O3 was used as an internal marker for the evaluation of digestibility. In the MARDI feed, the fish meal and soya bean meal were digested most by the fish: th...
