Black soldier fly (BSF) is becoming popular in the last few years. Several types of organic substrate have been tested as substrate for BSF larvae (BSFL) and resulted in valuable nutritional content of BSFL. The purpose of this study was to compare the nutritional content, fatty acid profile, and growth profile of BSFL grown between fermented Palm Kernel Meal (PKM) and fermented cow manure (CM). In total 3000 g of 7-day old larva (initial weight 0.044 g; length 12.44 mm) of BSF was randomly divided into two groups of triplicates. First group of BSFL was fed fermented PKM and second groups was fermented CM. After 15 days, BSFL was harvested, cleaned, dried, and separated between meal and oil. The BSFL meal was analyzed for proximate (Moisture, ash, crude protein, crude lipid, and carbohydrate), while oil for lipid profile. The growth of BSFL from two groups was determined by measuring 20 samples of BSFL per replication. Present study revealed that BSFL reared at fermented PKM had significantly higher crude protein (47.34%), ash (13.18%), lauric acid, heptadecanoic acid, total unsaturated fatty acid than fermented CM, but lower moisture (1.83%), crude lipid (4.31%), carbohydrate (33.34%), palmitoleic acid, myristoleic acid, linolenic acid, and arachidic acid. Linolelaidic acid and weight of BSFL grown in either fermented palm kernel meal or cow manure had no significantly difference. Present study suggested that both fermented PKM and CM can be used as substrates for growing BSFL that can convert into useful nutritional value. |
