Nutritional evaluation of protein isolate from rubber seed in
the diet of Labeo rohita: Effects on growth performance,
nutrient utilization, whole body composition and metabolic
enzymes activity
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)
