A completely randomized design was
used to study four experimental diets; 0, 3.75, 7.5
and 15 g ethanol turmeric extract/kilogram of feed
that were randomly assigned to each group. The
results showed that the groups fed with ethanol
turmeric extracts had no significant (P > 0.05)
differences in survival rate and feed conversion
ratio of white shrimp when compared to the
control. However, the body weight gain and
percentage average day growth (Table 2) were
significantly (P < 0.05) different. The survival rate
of mixed feed with 15 g/kg ethanol turmeric extract
(74 ± 4 %) was tested by the paired t-test and was
significantly (P < 0.05) different when compared
to the control (48 ± 6 %). The results suggested
that ethanol turmeric extract in the diet could not
improve the feed conversion ratio in white shrimp,
but the addition of 15 g/kg ethanol turmeric extract
in the feed could improve body weight gain,
percentage average day growth and survival rates.
This was consistent with the results reported for
Macrobrachium rosenbergii de Man (Wanprapa,
2004).
