Abstract

The fermented fish silages produced with Streptococcus spp., Lactobacillus brevis, Lactobacillus plantarum, Pediococcus acidilactici and Enterococcus gallinarum, and formic acid silages were compared for production of two discard fish silages (Equulites klunzingeri and Carassius gibelio). The E/NE ratio of spray-dried fish silages was determined in range of 0.80-1.10 for E.klunzingeri and 0.80-0.90 for C. gibelio silages. Pediococcus acidilactici and En. gallinarum groups had greater antioxidant activity than other silage groups. The DPPH radical scavenging ability was found as 6.14%-14.71% and 6.99%-13.36% for E.klunzingeri and C. gibelio silages, respectively. The OMD, ME and NEL values were determined in range of 69.74%-80.08%, 6.38-8.65 MJ/kg DM and 6.45-7.49 MJ/kg DM, respectively for spray-dried E.klunzingeri silages and 81.18%-86.62%, 8.97-9.61 MJ/kg DM and 7.61-8.08 MJ/kg DM, respectively, for spray-dried C. gibelio silages. According to the nutritional and chemical evaluation, spray-dried fish silages have great potential as a feed components because of high rate of digestibility and nutritious components.
