SUBSTITUTION OF SOYBEAN MEAL WITH INDIGOFERA LEAF FLOUR (Indigofera sp.) IN GROWING FEED OF STRIPED CATFISH (Pangasianodon hypophthalmus)

Soybean meal is one of the feed ingredients that still imported, so indigofera leaf flour tried as an alternative to local reduce costs. The purpose this study was determine effect (Indigofera sp.) a substitute for soybean on growth performance enlargement striped catfish (Pangasianodon hypophthalmus). This used completely randomized design with 4 treatments and 3 replications. P1 (without substitution flour), P2 (substitution 10% P3 20% P4 30% flour). data obtained were analyzed using analysis variance (ANOVA) further tested Duncan's test. Based statistical analysis, test feeding had significant (p<0.1) absolute weight growth, specific rate, efficiency yield not significantly different (p>0.1) length survival rate fish. results showed use up limit able provide relatively better than 30%.
