Each diet
was fed to the triplicate groups of shrimp for 30 d. Percent body weight gain and condition factor
of shrimp significantly increased with the increasing levels of dietary vitamin B6 up to 137.13 mg/kg
diet. Exceeding this level, however, did not further improve the weight gain. The survival rate also
increased at each incremental increase of dietary vitamin B6, but no significant increase was observed
beyond 65.69 mg/kg. B.79, 96.97, 137.13, and 189.56 mg/kg, respectively.
