Abstract

THE EFFECTS OF SUBSTITUTION OF FISH MEAL WITH MAGGOT MEAL OF  BLACK SOLDIER (Hermetia illucens) IN RATION ON BROILER’S CARCASS AND ABDOMINAL LIPID PERCENTAGE’S. Maggot meal of black soldier (Hermetia illucens) as an alternative feed to substitute fish meal have been used in poultry ration. In recent years, researches have conducted some experiments in substituting fish meal with maggot meal of black soldier (Hermetia illucens) as an alternative feed. A research evaluating the effects of substitution of fish meal with maggot of black soldier on carcass and abdominal lipids of  broiler has been done for six months at Department of Animal Science, Sam Ratulangi University, Manado. Eighty broilers (day of chicks) strain CP 707 were allocated in 20 units of cages. Completely Randomized Design with 5 treatments and 4 replications was used. The treatments were R0 = 100% fish meal (0% maggot meal in the ration), R1 = 75% fish meal + 25% maggot meal (3.75% maggot meal in the ration), R2 = 50% fish meal + 50% maggot meal (7.5% maggot meal in the ration), R3 = 25% fish meal + 75% maggot meal (11.25% maggot meal in the ration),and  R4 = 100%  maggot meal (15% maggot meal in the ration). Variables measured were carcass and abdominal lipid percentages. Carcass and abdominal percentage in this experiment were 68.47 – 73.17% and 3.08 – 4.38%, respectively. Analysis of variance showed that there were significant (P<0,01) effects of treatments on carcass and abdominal lipid percentages. Tukey’s test showed that R4 or 100% substitution of fish meal with maggot meal (15% maggot meal in the ration) was lower compared to R0, R1 and R2,however, there were no significant difference among R0, R1, R2 and R3, while R3 was not significantly different with R4 for carcass percentage. Abdominal lipid percentage of R4 was significantly higher compared to R0, however, there were no significant difference among R1, R2, R3 and R4. Based on carcass and abdominal lipid percentage’s. It can be concluded that fish meal can be substituted by maggot meal up to 75% (11.25% maggot meal in the ration).
