Abstract :

In this survey, effect of Probiotic Bactocell (Consist of Pediococcus acidilactici MA 18/5M) was examined on feeding, growth performance and survival rate of grass carp (Ctenopharyngodon idella) fry. 300 fish were prepared and fed by special diet made according to American Soybean Association International Marketing (ASA-IM) principle. Four different treatments (control group with no probiotic, treatments 1, 2 and 3 each containing 0.1, 0.2 and 0.3 g probiotic Kg-1 of basal diet, respectively) were designed in triplicates. Results showed that Bactocell has no significant effect on feeding and growth parameters, but treatments 1 and 3 had the best performance. Although there weren’t any significant differences between fishes treated by 0.1 and 0.2 g Kg-1 Bactocell, most of the growth factors including body weight increase, percentage of body weight increase, specific growth rate and protein efficiency rate were better in fishes fed by the diet supplemented with 0.1g Kg-1 Bactocell.
