ABSTRACT

Chicken feather meal from waste chicken feathers. Chicken feather is a waste from a Chicken Piece House (RPA). Chicken feather waste have the potential to be used because have a high protein content of 80-90%. But waste chicken feathers have a low digestibility because it contains 8.8% of the keratin protein content. The use of chicken feather meal as animal feed in this study should be through touch fermentation technology with fungus isolates from soil chicken cage. The aim of this study was to test the digestibility feed with the addition of chicken feather meal fermented by fungus isolates from soil chicken cage. This research was carried out by isolating the fungus from soil chicken cage to get a fungus isolates from soil chicken cage capable of degrading keratin in the chicken feather. Fungus isolates obtained are used to fermentation chicken feather meal and then analyzed the protein content after fermentation. Chicken feather protein content after fermentation was tested using a completely randomized design (CRD) non factorial with 4 treatments and 3 ulangan. Chicken feather meal that has been fermented with some fungus isolates from soil chicken cage used as broiler chicken feed and chicken growth measurement (feed consumption, body weight gain and feed conversion) and feed digestibility coefficients. The results of research showed that fungus isolate from soil chicken cage better able to increase the protein content of chicken feather meal after fermentation is a fungus isolate inoculum Penicillium sp with as much as 3% with a chicken feather meal protein content of 90.90 %%, the growth of broiler chickens (feed consumption amounting to 415.6 gr / head / week, body weight gain of 230, 75 gr / head / week and feed conversion of 1.8) and feed digestibility coefficient of 28, 89%.
