The effect of silkworm pupae (bombyx mori) meal to substitute fish meal on production and physical quality of quail eggs (cortunix cortunix japonica)

Abstract

The aims of this study was to determine the effect of substitution of fish meal protein with silkworm pupae (Bombyx mori) on quail performances and egg quality. The experiment was a completly randomized design (CDR) with four treatments and four replications and ten birds of each replication. The treatment diets were R0: diet contain 8% fish meal, without silkworm pupae (control), R1: diet contain silkworm pupae subtituted of 25% fish meal protein, R2: diet contain silkworm pupae subtituted of 50% fish meal, protein and R3: diet contain silkworm pupae subtituted of 75% fish meal protein. The results showed that substitution of 25% up to 75% significantly (P<0.05) reduced feed conversion ratio, significantly (P<0.05) increased egg production and did not affecting physical quality of quail eggs. In conclusion, silkworm pupae can be used 25% up to 75% replacing protein fish meal.
