PENGGUNAAN RAGI ROTI (SACCHAROMYCES CEREVICIAE) DALAM PAKAN UNTUK MENINGKATKAN RESPON KEKEBALAN NON-SPESIFIK PADA IKAN NILA (OREOCHROMIS NILOTICUS)

Abstract

 Abstract - This research to seeing the effect of bread yeast (Saccharomyces cereviciae) in improving the respons non-specific immunity in tilapia (Oreochromis niloticus). Tilapia with an average weight of 31.83 g is maintain in five aquariums with a density of 5 tails per aquarium.
