One hundred and eighty L. rohita fingerlings were equally and
randomly distributed in six experimental groups in triplicate
following a completely randomized design (CRD). The experimental
trial for effects of andrographolide on growth, non-specific
immune parameters in L. rohita was conducted with feeding the
various level of andrographolide as control T0 (without andrographolide),
T1 (0.05%), T2 (0.10%), T3 (0.20%), T4 (0.40%) and T5
(0.80%) for a period of 42 days.
