Relative percentage survival of L. rohita after challenge with
A. hydrophila in different experimental groups is presented in Fig. 6.
The treatment groups fed with andrographolide supplemented diet
showed significantly (p < 0.05) high disease resistance against
A. hydrophila infection when compared with control group. The
highest percentage survival was recorded in T2 (74.06%) followed
by T1 (62.95%) and T3 (51.84%) groups.
