Abstract:
Objective: This study was conducted to evaluate the effect of sapu-sapu fish (Hypostomus plecostomus) as substitute of commercial feed on the production performance and eggs quality of Mojosari ducks. Materials and Methods: A total of 100 Mojosari laying ducks were distributed randomly into four dietary treatments with five replicates of five ducks. The treatments were P0 (mixture of 80% rice bran and 20% commercial feed), P1 (mixture of 90% rice bran and 10% sapu-sapu fish), P2 (mixture of 80% rice bran and 20% sapu-sapu fish), P3 (mixture of 70% rice bran and 30% sapu-sapu fish). Results: The results showed that the average weight gain during three month feeding trial for P2 and P3 were 136.6±41.78 g and 101.7±92.78 g which were significantly (p<0.05) higher than P0 and P1 which were 72.6±20.58 g and 46.9±33.07 g. Egg production of ducks fed on P0, P2 and P3 diets were 47.2±7.33%, 45±9.0% and 41±5.2% respectively, which was significantly (p<0.05) higher than those given P1 diet. The feed conversion ratio, egg weight and egg index were not affected by dietary treatments. While yolk color of ducks fed on P0 was 10.56±0.932 which was significantly higher than those fed on P1, P2 and P3. The egg and meat cholesterol of the ducks fed diet containing sapu-sapu fish was lower than those offered commercial feed (p<0.05). Conclusion: It was concluded that sapu-sapu fish can substitute up to 20% of commercial feed.
