Black Soldier Larvae Versus Fish Meal Concerning the Growth of Muscovy Ducks
Pham Tan Nha*, Le Thu Thuy
ABSTRACT
Black soldier flies are used to make animal feed with quite high nutritional content and enough nutrients to make animal feed. We aimed to explore the appropriate level of supplementation of black soldier fly larvae in the diet of Muscovy ducks at 7-12 weeks old. A total of 200 Muscovy ducks were randomly assigned to five dietary treatments. The treatments named as following: CTL - control diet with fishmeal; LP20, LP40, LP60 and LP80 as replacing 20%, 40%, 60% and 80% of fishmeal protein with larval protein (LP) in the control diet with four replications, each replication with 10 ducks (5 males and 5 females). The results showed that the weight gain of the LP20, LP40, and LP60 treatments was as high as the CTL treatment. The FCR of ducks at CTL treatment (3.40) and LP20 treatment (3.44) was significantly (P<0.05) lower than LP60 treatment (3.52) and LP80 treatment (3.59). It is possible to replace 60% of the fish meal protein with the black soldier fly larvae protein, providing the highest profit without affecting the growth of broiler Muscovy ducks during the 7 to 12 weeks period.
