The research aimed to determine effect of addition probiotic in artificial feed to growth and retention proteins on fingerling of baung (Hemibagrus nemurus). This research used a completely randomized design (RAL) with one factor, five treatments and 3 replications. The treatment given was different concentrated of probiotic in feed. Consisting of: control (without the addition of probiotic), P1 (addition probiotic of 2 ml/kg feed), P2 (4 ml/kg of feed), P3 (6 ml/kg of feed) and P4 (8 ml/kg of feed). Feed protein content of 28,33%. The results showed addition of probiotic 2, 4, 6, and 8 ml into artificial feed did not give a significant effect (P>0,05) on the feed efficiency, retention of protein, specific growth rate, and survival rate fingerling of baung. The best treatment contained in P4 (8 ml/kg of feed) with 53,92% digestibility of feed, feeding efficiency 26,46%, protein retention 22,43% and the specific growth rate of 2,05%
