Abstract
A 45-days feeding trial was conducted to study the immunomodulatory effect and interferon gamma gene expression of dietary fucoidan rich seaweed extract (FRSE) from Sargassum wightii on Pangasianodon hypophthalmus fingerlings. One hundred and eighty fingerlings were distributed into six experimental groups in triplicates. Each group was stocked with 10 fish and fed to satiation with iso-nitrogenous (34.96 � 0.09–35.18 � 0.03 CP%) and iso-caloric (368.65 � 0.86–375.09 � 0.26 Kcal/100 g) purified diets containing either 0% FRSE (control), 1% FRSE (TF1), 2% FRSE (TF2), 3% FRSE (TF3), 3% seaweed powder (TS3) or 6% seaweed powder (TS6) in the feed. After feeding trial the experimental fish were challenged with Aeromonas hydrophila. Immunological parameters like respiratory burst activity, lysozyme activity, phagocytic activity and total leukocyte count (TLC) were increased with the increasing level of dietary FRSE, whereas serum Albumin/ Globulin (A/G) ratio and blood glucose level exhibited decreasing trend (P < 0.05).
