In the first phase of the experiment, two hundred common carp fishes(1gr) in two tanks with capacity 250 liters’ water were used for producing biofloc. Inthe second stage, the effect of 0, 0.5, 1, 1.5 and 2% of produced biofloc with ration70 to 30 concentrate to forage on in vitro gas production and digestibility wasdetermined. The data were analyzed in a completely randomized design (5treatments and 4 replicates). The results showed that there was no significantdifference in potential and rate of gas production and dry matter digestibilitybetween treatments. The highest amount of truly digested organic matter, cell walldegradability, and NDF digestibility was related to the treatment containing 2%compared with the other treatments (108.4, 67.8, and 32.5, respectively). The10microbial biomass efficiency, microbial biomass and PF of treatments containingbiofloc were more than control treatment (P < 0.05). On the base of this trial,treatments containing biofloc especially the high levels of biofloc had a morepositive effect on digestibility and fermentation of experimental diets, thereforebiofloc produced from the fish breeding system can be used as a useful supplementin ruminants.
