SUBSTITUSI SILASE SECARA KIMIAWI LIMBAH PADAT SURIMI IKAN SWANGGI (Priacanthus macracanthus) PADA TEPUNG IKAN TERHADAP RETENSI ENERGI DAN RASIO KONVERSI PAKAN BENIH IKAN NILA (Oreochromis niloticus)
Abstract: Swanggi surimi waste
can be processed into economically valuable source of protein through chemical
treatment processes produce crude protein content ranging from 51%. Results of
high energy retention and reduced feed conversion ratio of solid waste as a
substitute swanggi fish surimi fish meal is expected to optimize the growth of
tilapia with lower feed prices, thereby reducing the high cost of feed in
aquaculture.
This study aims to determine the chemical silage substitution of solid
waste swanggi fish surimi (P. macracanthus) in fish meal. The experimental
design completely randomized design (CRD) with four treatments with five
replications. The treatment used is the number of different proteins in each feed
rations. The main parameters are observed energy retention (%) and feed
conversion ratio. Analysis of data using analysis of variance (ANOVA) and
followed Duncan's multiple range test.
These results indicate that substitution is chemically silage solid waste
swanggi surimi fish in fish meal provides highly significant effect (p
<0.05) on the retention of energy and feed conversion ratio tilapia fish.
The average retention of the highest energy on a few observations are in
treatment P3 (67,90a ± 0.86%) and the lowest at P0 (64,72b ± 1.17%). Average
feed conversion ratio was lowest for the treatment P3 (2,41c ± 0.028) and the
highest pda P0 (2,50a ± 0.018).
