Abstract

The aim of this research was to know the effect of length of A3-51 probiotic  supplementation  to the number   of   intestine   Enterobacteriaceae.   Research   used   experimental   method   using   Completely Randomized  Design  which  was  based  on  4   treatments  i.e.  La  (without  probiotic),  Ll  (probiotic supplementation for 7 days), L2 (probiotic supplementation for 14 days), L3 (probiotic supplementation for 21 days). Each  treatment was repeated 3 times. The result showed that the length period of A3-51 probiotic   supplementation  very   significantly  (P<0,01)  increased  the  intestine   Enterobacteriaceae number. However, in the same time the amount of pathogenic Enterobacteriaceae decreased. In addition, probiotic supplementation improved protein, fat, and carbohydrate digestions.   Key words: Enterobacteriaceae, intestine, probiotic, nutrient digestibility

Abstract

Objectives of this research was to know the effect of probiotic A3-51 supplementation on food to the total number of bacteria in kidney and mortality of Oreochromis niloticus after challenge test with Aeromonas hydrophila and Aeromonas salmonicida achromogenes. This research was consisted of two experiment, the first was to know the highest immunity level of fish based on the number of macrophage and its phagocytic activity. Meanwhile, the second was to know the immunity level of fish challenged with A. hydrophila and A. salmonicida achromogenes by intra-peritoneal injection. The experiment used Completely Randomized Design in triplicates. The result from the first experiment showed that the highest non spesific immune system response, by means number of macrophage, was found 21 days treatment. The second experiment showed that the highest total number of bacteria in kidney and mortality level were 20.23 x 108 cells/g and 46.67%, respectively, both was found in control fish injected intra-peritoneally with A. salmonicida achromogenes.
