Effects of dietary supplementation of Lactobacillus pentosus PL11 on the growth performance, immune and antioxidant systems of Japanese eel Anguilla japonica challenged with Edwardsiella tarda
چکیده انگلیسی

The aim of this study was to determine the efficacy of dietary administration of Lactobacillus pentosus PL11 on growth performance and the immune and antioxidant systems in Japanese eel Anguilla japonica challenged with Edwardsiella tarda. A total of 75 Japanese eels (24.63 ± 0.83 g) were grouped into 5 treatment diets which were a control diet (C) without E. tarda and 4 treatment diets with E. tarda challenge, including C for E. tarda challenge (NC), C plus L. pentosus PL11 supplemented diet (108 cfu g−1) (T-PL11), C plus L. pentosus KCCM 40997 supplemented diet (108 cfu g−1) (T-Lp) and C plus Weissella hellenica DS-12 supplemented diet (108 cfu g−1) (T-Wh) for 5 weeks (4 week before and 1 week after challenge). The results showed enhanced growth performance in fish fed the diet containing L. pentosus PL11 compared to others. The growth performance parameters including specific growth rate (SGR) and weight gain (WG), feed intake (FI), feed conversion ratio (FCR) and survival were significantly (P < 0.05) higher in fish maintained on L. pentosus PL11 supplemented diet compared to C and NC. T-PL11 group also shows a significant increase in the levels of plasma immunoglobulin M, CAT and SOD activities compared to NC. Hematological parameters and mieloperoxidase were significantly better in fish fed the L. pentosus PL11 supplemented diet than in the control. L. pentosus PL11 supplementation recover the reduced expression of SOD, CAT and heat shock protein 70 genes in liver and intestine in pathogen challenged fishes. In conclusion the result of the current study demonstrated L. pentosus PL11 potential as an alternative to antibiotic supplementation to improve the growth and health performance of Japanese eel (A. japonica).


► Lactobacillus pentosus PL11 had antibacterial activity in pathogen challenged Japanese eels.
► L. pentosus PL11 showed better specific growth rate and feed conversion ratio.
► L. pentosus PL11 enhances immune/antioxidant responses in pathogen challenged eels.
