ABSTRACT
This research were conducted from November 2022 to January 2023. This study aims to determine the effect of feeding containing fermented chicken feather flour on feed efficiency and growth of striped catfish fry. The test fish used had a weight of 2,85 ± 0,33 g. The containers used for observing fish growth were 15 units of floating net cages made of gauze measuring 1x1x1 m with a stocking density of 25 individuals/800 L and 5 units of aquariums measuring 60x35x40 cm as containers for observing the digestibility of feed with a stocking density of 25 individuals/63 L. This research method used a one-factor Completely Randomized Design (CRD) with 5 treatment levels and 3 replications. The treatments in this study were P0 (feed without fermented feather meal), P1 (feed containing 7,5% fermented feather meal), P2 (feed containing 15% fermented feather meal), P3 (feed containing 22.5% flour). Fermented chicken feathers) and P4 (feed containing 30% fermented chicken feather flour). The test feed protein was about 40%. The amount of feed given is 5% of the body weight of the fish with a frequency of 3 times a day, namely morning, afternoon and evening. Fish rearing was carried out for 56 days. To measure the digestibility of feed by giving feed containing an indicator of 0,5% Cromium Oxidate (Cr2O3) . Feed is given 3 times a day, namely morning, afternoon and evening as much as 5% of the body weight of the fish. The faeces excreted by the fish are then collected and dried. The feces collected were analyzed for protein content and Cr2O3 to obtain feed digestibility and protein digestibility data. The results of this study indicated that the best treatment was P3 (feed containing 22,5% fermented chicken feather meal) resulting in feed digestibility of 55,36%, protein digestibility of 85,39%, feed efficiency of 83,59%, protein retention of 36,33%, specific growth rate of 3,38%, and survival of 92,00%.
