The Utilization of Feather Meal Fermented Using Bacillus sp. From Tiger Shrimp (Penaeus monodon) For Fish Feed of Barramundi (Lates calcarifer, Bloch) Fingerling

Abstract

The research was conducted on 1 May-1 July 2017. The purpose of this study to
evaluated the uses of feather meal fermented in fish feed and to determine the
number of feather meal fermented in fish feed formulation of barramundi (Lates
calcarifer, Bloch), the effect on digestibility, growth, feed efficiency and protein
retention. This study uses a completely randomized design (RAL) with one factor,
the level 5 treatment and 3 replications. Treatments with feather meal
fermentation, P0 (0%), P1 (5%), P2 (10%), P3 (15%), P4 (20%). Feed protein
content of 47,52%. The result show that the highest treatment contained in P2.
Use feather meal fermented formulated in the feed as much as 10%, produces the
best barramundi fish seed growth is digestibility of the feed 65,16%, digestibility
of protein 48,75%, the feed efficiency of 26,33%, retention of protein 41,67% and
specific growth rate of 1,71%.
