Judul: Efektivitas Penambahan Mannan Oligosakarida dan Vitamin C sebagai Feed Additive terhadap Kinerja Pertumbuhan ikan lele (Clarias sp.)
Abstrak: This study aimed to test of addition mannan oligosakarida (MOS) and vitamin C as feed additive on growth performance of Catfish (Clarias sp.). The feed used in this study is comercial feed with 39.4% protein dry weight content with the addition of feed additive is 3.6 g/kg. A total of 15,000 catfish (0.268 ± 0.26 gram) was reared for 20 days in tank (3 x 6x 0.5 m3) which has been equiped with aeration system. Fish feeding was conducted three times at 06.00, 16.00 and 24.00 (at satiation). The experimental design was a completely randomized design with 2 treatments and duplicate. The result showed that the amount of feed intake, protein retension and daily growth rate not significantly different (P>0,05). However, the biomass, feed conversion ratio (FCR) and survival rate in catfish with addition of feed additive in feed have significantly different (P<0,05). This result showed that the addition of MOS and vitamin C in catfish feed can decrease FCR and increase final biomass and survival rate (SR).

Judul: Efektivitas Penambahan β-glukan dan Vitamin C sebagai Feed Additive terhadap Kinerja Produksi Ikan Lele Clarias sp..
Abstrak: This experiment was conducted to evaluate the addition of β-glucan and vitamin C in the feed on the production of catfish Clarias sp.. Juvenile with an average weight of 0.26 ± 0.01 g stoced in the plastic lined pond with a size of 6 x 3 x 0,5 m3 a density of 15,000 juveniles per pond and reared for 20 days. This experiment consisted of 2 treatments and 2 replications. In the first treatment, fish was fed with commercial feed without of β-glucan and vitamin C, whereas in the second treatment fish was fed with commercial feed with β-glucan and vitamin C addition. Fish were fed at 06.00, 16.00, and 24.00 WIB to satiation. The results showed that the fish was fed by commercial feed with of β-glucan and vitamin C addition had better production compared with control.
