Evaluation of the Performances and IOFCC of Broilers Fed the Whole, the Skinless, and the Skin of Leubim Fish Waste Meals Based Partial Replacement Feed of Commercial Diets

This study aimed to evaluate the performances of broilers fed the commercial diet CP511 (CCP) partially substituted with leubim fish waste meal (LFW) processed into different parts i.e. whole leubim fish waste meal (LFWW), skinless leubim fish meal (LFM‒S), and leubim fish waste skin meal (LFWS), each mixed with yellow corn (YC) and top mix (TM). This research was conducted at the Field Laboratory of Animal Husbandry (LLP), Syiah Kuala University from March 17 to April 21, 2021. This study used 100 DOC broiler chickens strain CP 707 and commercial local fish meal (CFM). The study used a completely randomized design (CRD) consisting of 5 treatments and 4 replications. The treatment was CCP= 100% CP511 (control+) and the CCP replaced with: CFM (control-), LFWW, LFM‒S, and LFWS with the equal amount of 8% each and the addition of 8% YC + 0.5% TM each. The results showed that although statistically no significant differences (P>0.05), the inclusion of LFW meals in the form of LFWW, LFM‒S, or LFWS plus YC + TM each to substitute partially CCP tended to have higher body weight gain (BWG), final body weight (FBW), feed intake, and better feed conversion ratio (FCR), and protein efficiency ratio (PER), while protein intake (PI) significantly increased (P
