Pampanga State Agricultural University, PAC, Mtagalang, Pampanga. ADVISER: BERNARDO E. MARTIN, M.S.A The study conducted to determine the growth performance of two strains broiler chicken as affected with different levels of black soldier fly larvae (hermetia illucens) as their additional protein source for growing broiler chicken. This study conducted from May 13 to June 17, 2022 at Tent City Ayala, Magalang, Pampanga. One hundred eighty heads broiler randomly distributed into six treatments replicated three times following the 2x2 factorial experiment arrange in completely randomized design (CRD). Each treatment composed of thirty heads. The treatments were: Factor A - A\BO0control/pure commercial feeds, A1B1 - 7% of black soldier fly larvae and A1B2 - 11% of Black soldier fly larvae. Factor B - A2B0control/pure commercial feeds, A2B1 - 7% of black soldier fly larvae and A2B2 - 11% of Black soldier fly larvae. Significant differences noted in all parameters considered.
