ABSTRACT
The current study was carried out to investigate growth performance of Labeo rohita fingerlings fed with Lactobacillus rhamnosus supplemented plant by products based feeds. The study comprised of two experimental and one control groups. In treatment 1 (T1), fish were fed with soybean meal along with L. rhamnosus. In treatment 2 (T2), fish were fed with sunflower meal along with L. rhamnosus. The control group was served with commercial feed. Initial mean weights of the experimental fish was recorded as 40.00 ± 1.00, 40.33 ± 0.76 and 40.01 ± 1.00 g for T1, T2 and control groups, respectively. The highest weight gain was found in T1 (747.96 ± 1.9 g) and control group (479.35 ± 1.8 g). Significant differences were found in the feed conversion ratio between control group (2.02 ± 0.07), T1 (1.48 ± 0.03) and T2 (1.47 ± 0.02). Survival remained 100% in all the treatments. Water quality parameters differed insignificantly for different treatment groups and remained in favorable range throughout the study period. All the treatments showed lower values of fat contents and higher values of crude protein. No negative change was observed in the histological parameters of the liver and intestinal tissues for the fishes fed with plant based feeds added with probiotics. Conclusively, fish production can be enhanced with the addition of probiotics in the feed derived from plants.
