Description A 45-day feeding trial was conducted to evaluate
the effect of dietary jamun tree leaf (JL) on the
antioxidant defence system-based disease resistance in
juveniles of Trachinotus blochii. The juveniles of
snubnose pompano were distributed into four treatment
groups in triplicates. Each treatment was fed with a diet
containing either 0 (0JL), 0.5 (0.5JL), 1 (1JL) and 1.5%
JL (1.5JL) in the feed. After feeding trial, the fishes were
experimentally infected with Vibrio parahaemolyticus.
The activities of oxidative stress enzymes such as superoxide
dismutase and catalase were found to be increasing
with increasing level of dietary JL incorporation, and the
lower value was witnessed in control group in pre- and
post-challenge. After challenge, the alanine and aspartate
aminotransferase activities in all the treatments were
significantly increased (P < 0.05) than the pre-challenge
condition and exhibited reverse trend with the antioxidant
enzymes. The alkaline and acid phosphatase activities
were found higher in 1.5JL group and showed
significant difference (P < 0.05) among the treatments.
The respiratory burst activity and liver glycogen content
showed an increasing trend as the level of inclusion of JL
increased in the diet. The acetylcholinesterase activity
was significantly plunged (P < 0.05) after experimental
infection, and JL diet fed groups showed better activity.
After experimental infection with V. parahaemolyticus,
the highest relative percentage of survival was observed
in 1JL and 1.5JL groups. Hence, dietary supplementation
of jamun tree leaf at the level of 1% is adequate to reduce
the oxidative stress and improved the innate immune
status through antioxidant defence system.
