Pairing Coconut and Candlenut Oil as Feed Supplement in Low Protein Diet with Addition Se on Feed Efficiency of Red Nile Fish (Oreochromis Niloticus)

Abstract

Nutritional Balance in feed is critical to improve the efficiency of feed. The use of oil in omnivore fish can serve as a spare protein-energy provider in addition to carbohydrates. Not only is the adequacy of the quantity and quality of protein that must be guaranteed, often the energy value is not as predicted, so the addition of high-calorie ingredients is important. Efforts to replace some of the protein functions as an energy source, by feed oil supplements from pairing coconut flesh as saturated fat combined with candlenuts as unsaturated fat, with added of trace element Se, thus improving the optimum use of protein in freshwater fish.This study aims toget the ratio and type of fat (saturated and unsaturated) of feed formula (low protein 28%) with selenium supplementation, compared with high protein (32%), which can increase feed efficiency of red nile tilapia (Oreochromis niloticus) fingerling phase. The preparation stage found that pairing coconut fat supplements were dominated by saturated fatty acid as lauric (42.67%). In contrast, candlenut fats contained unsaturated fatty acids, linoleic (34.4%), and oleic (48.99%), so the use of candlenut oil (0%, 2% and 4%) can increase the ratio of unsaturated fatty acids in the feed. Treatments consist of 6x3 with Completely Randomized Design by a ratio of the source of unsaturated fat and saturated fat with mineral addition Se. R1was low protein feed without supplements; R2 and R3were low protein feed containing ratio of unsaturated-saturated fat 1:1 (mixture of oil were 2% of each) without and with addition of Se, and then R4 1:2 (coconut oil); 2:1 (candlenut oil) and R6 high protein without of fat supplements 2:3, produces normal physiological (hematologic and digestive) images for tilapia health.The Result showed that coconut and candlenut mixed-oil 2% of each with addition of Se 0.15 ppm, was the best feed efficiency in tilapia ranged from 50.14-57.93% and protein efficiency ratio 1.72 -2.06.
