EFEK ENZIM PAPAIN PADA BERBAGAI PAKAN KANDUNGAN PROTEIN BERBEDA TERHADAP PRODUKSI DAN KECERNAAN PROTEIN AYAM KAMPUNG

The research was evaluator to know the effect of papain enzyme on low crude protein content of native chicken feed. The research used 12 treatments were P1E1 (17% crude protein of feed + 0,05% enzyme, w/w), P1E2 (17% crude protein of feed + 0,075% enzyme, w/w), P1E3 (17% crude protein of feed + 0,1% enzyme, w/w), P2E1 (16% crude protein of feed + 0,05% enzyme, w/w), P2E2 (16% crude protein of feed + 0,075% enzyme, w/w), P2E3 (16% crude protein of feed + 0,1% enzyme, w/w), P3E1 (15% crude protein of feed + 0,05% enzyme, w/w), P3E2 (15% crude protein of feed + 0,075% enzyme, w/w), P3E3 (15% crude protein of feed + 0,1% enzyme, w/w), P4E1 (14% crude protein of feed + 0,05% enzyme, w/w), P4E2 (14% crude protein of feed + 0,075% enzyme, w/w), and P4E3 (14% crude protein of feed + 0,1% enzyme, w/w). All treatments were repeated 3 times. Research method using Completely Randomized Design (CRD). The research result showed that using papain enzyme on different crude protein level of native feed dosen’t give significant influence for all variables, except on crude protein digestibility which giving very significant effect. The using of papain enzyme 0,075% concentration (w/w) in 17% and 16% crude protein level giving good weight gain and crcass weight of native chicken that was maintained for 2 months perio
