Abstract
In the present study conducted for 90 days (3 months), probiotic S. cerevisiae was taken to observe its effect on growth performance and haematology of 160 healthy Catla fingerlings with an average weight and length of 9.3 gm , 7.2 cm respectively. Four treatment groups with four replicates were formed, Control without probiotic supplementation and three group T1, T2, T3 with different concentration of probiotic i.e 2%, 4% and 6% S. cerevisiae. All 160 fingerlings were distributed in four replicates of each group, with 10 fingerlings in each 100 L capacity tub. All growth parameters and water quality parameters were measured fortnightly. All three probiotic supplemented group showed significant (P ≤ 0.05) difference in growth and haematology as compared to control group. In comparison to unsupplemented control group all growth parameters were observed higher in all three supplemented group and maximum values were observed in T2 (4% probiotic). Maximum survival rate with value 95% was also observed in T2. All haematology parameters such as Hb, RBC, WBC, PCV all were observed significantly (P ≤ 0.05) higher in T2 and least values in unsupplemented control group. Allmost water quality parameters monitored for whole experimental period were found within acceptable range. These results suggested that administration of probiotic (S. cerevisiae) in feed confers beneficial effects for fish culture, considering growth performance, haematology and water quality.
