Effect of probiotics on growth and health status of Labeo rohita

A feeding trial of 90 days was conducted to check the effect of probiotic on the growth of Labeo rohita. Four different doses of feed T1 (0.5??107), T2 (1 ??107), T3 (1.5??107) and control were formulated. Fish were fed at the @3% body weight, twice a day total of 300 L. rohita having an average weight of 10-15 g were collected from the University of Veterinary and Animal Sciences Ravi Campus, Pattoki (UVAS) fish ponds. Total 12 aquaria were used and 25 fish in each aquarium were stocked such as control, T1, T2 and T3. Initial weight and length of each fish were recorded before stocking. Water quality parameters were checked daily. On weekly basis weight and length was examined, at the end of the experimental trial; the final weight and length were resulted. Treatment T2 (57.11??0.51) growth parameters were recorded significantly, while T3 (42.28??0.35) and T1 (48.70??0.06) were recorded non-significant. Treatment T1 was a significant result of hematological parameters while T2 and T3 were recorded non-significantly. In all treated groups, the physico-chemical parameters were remained statistically non-significant throughout the experimental trial.
