ABSTRACT
Tenebrio molitor larvae are an alternative feed option for protein sources. This research includes 2 phases. Phase 1. Effect of different medium compositions on the production and nutritional content of Tenebrio molitor larvae. Phase 2. Effect of Tenebrio molitor larvae in the diet on broiler performance. Phase 1 used a completely randomized experimental design (CRD) with six treatments and three replications. The treatment variations were treatments A (100% Concentrate), B (100% Chicken Manure), C (50% Concentrate + 50% Rice Bran), D (50% Concentrate + 50% Chicken Manure), E (50% Concentrate + 50% Tofu Dregs) and F (50% Concentrate + 50% Coconut Dregs). The variables observed were crude protein content (%), fat content (%), and larval production (g). The research method in phase 2 used a completely randomized design (CRD) consisting of 5 treatments and four replications. The treatments were 0%, 2.5%, 5%, 7.5%, and 10% of Tenebrio molitor larvae in the diet. The variables observed were feed consumption, average daily weight gain, feed conversion, carcass percentage, abdominal fat percentage, and taste of meat carcass. Phase 1 demonstrated that different substrate compositions had significant effects (P<0.01) on crude protein, fat, and larvae production. The conclusion of phase 1 was that treatment E (50% concentrate + 50% Tofu dregs) was an effective treatment and obtained protein content (71.13%), fat content (17.60%), and production of larvae (105.12 g). Phase 2 showed that the use of 12% Tenebrio molitor larvae (substituted 100% fish meal) could maintain the performance of broilers.
