Abstract: 

The commercial probiotic (Bactocell) in aquaculture were permitted and registered in 2009 in Europe. The probiotic with beneficial changes in the intestinal microbial population and lactic acid production leades to improved growth and survival of fish and shrimp production. In this study, the influence of, Pediococcus acidilactici, supplementation was investigated on growth parameters and food efficiency in rainbow trout. All experiments were triplicated and designed in three different administrations of probiotic to the diet in order to study the comparative effects of three different doses Bactocell probiotics on some rainbow trout growth factors during 4 week in experimental treatments : In the first group, 1 g Probiotic Bactocell was added to 10 kg fish food. In the second group, 2 g probiotic Bactocell was supplemented to 10 kg food. In the third group, 3 g probiotics Bactocell was added to 10 kg ration and in control group, concentrate food with no probiotic-supplemented was used. Initial fish weight was 400 g. Based on results, FCR rate of all treatments, respectively (0.84, 0.78, 0.82 and 1.47) obtained with no significant difference (P>0.05).The specific growth factor (SGR) of probiotic treated groups were 1.4, 1.5 and 1.4 respectively and significantly different (P<0.05) from that of control group (0.96,the lowest amount). Finaly, mean fish total length in all groups wasn’t significantly different (P> 0.05). The results indicate that dietary probiotic Pediococcus acidilactici to 2 g per 10 kg of diet has positive effects on the growth of rainbow trout.
