The treatments were a control diet with only fish meal protein (SF0) and in the others fish meal protein was replaced by seafish by-products at different levels of 25% (SF25), 50% (SF50), 75% (SF75) and 100% (SF100) of the amount of the fish meal protein of the SF0 diet. Premix- vitamin was supplied at 0.3% for all treatments. Water spinach was offered with the same amount of 30g in fresh weight/duck/day to provide vitamins and minerals.

The results of the experiment on Nong nghiep ducks showed that the DM and CP intakes were significantly higher in the SF75 treatment (P
