Abstract

This study was conducted to evaluate the effect of feeding with different lipid content on growth performance and body composition in Kelabau (Ostechilus melanopleura Bleeker). Four experimental diets isonitrogen, isoCHO and different lipid levels. A, B, C and D feeds contained 5%, 7%, 9% and 11% lipid levels respectively. Kelabau obtained from the cultivation in Balai Benih Air Tawar Mandiangin with an average weight of 3.18 g with a density of 20 individuals maintained in plastic tubes measuring 54.3 cm x 38 cm x 31.5 cm and filled 40 liters of water. Kelabau fed 2 times a day on at satiation for 60 days. The result showed that fish fed diet B (7%) had higher growth performance and feed utilization compare the other groups (C,D and A) (P <0.05). The increase in lipid administration in Kelabau from 5% to 7% have an effect protein, lipid and energy retention.
