Panchagavya Dietary Supplementation with Probiotic Lactobacillus: Impact of Immunity and Disease Resistance in Oreochromis mossambicus

In the current investigation suggested that the immune stimulatory effect of Panchagavya probiotics Lacto bacillus on the growth, immunity and disease resistance of Tilapia, Oreochromis mosaambicus and improve the disease resistance against Edward siella tarda and Aeromonas hydrophila. The efficacy of basal diet (BD) of the following experimental diets were treated with O. mosaambicus: T1 (Basal diet + Panchagavya); T2 (Basal diet + Lactobacillus); T3 (Basal diet + Panchagavya + Lactobacillus) and control. Various immune parameters were examined at 7, 14, 21 and 28 days post-feeding. Fishes were challenged with A. hydrophila and E. tarda 30 days post-feeding, and mortalities were recorded over 14 days post infection. Results showed that administration of Panchagavya with probiotics of Lacto bacillus combination for 28 days had significant effects (p<0.05) on the specific and non-specific immune response of O. mossambicus. Dietary administration of O. mossambicus from Panchagavya with probiotic feed significantly increased the neutrophil, lysozyme, antiprotease and myeloperoxidase activities were gradually increased respectively. The highest ROS and RNS (p<0.05) were observed in the fish group feed a diet containing Panchagavya and Lacto bacillus. Furthermore, fish feed a Panchagavya-enriched diet with Lactobacillus had significantly higher (p<0.05) post-challenge relative percent survival (RPS). Considering these promising benefits, the Panchagavya with probiotic Lacto bacillus supplementation in equal proportions for 30 days can effectively impair the immunity of O. mossambicus.
