Abstract:
The aim the research is to increase the reproductive potential of L. festivus female that is time matured
gonads, somatic ovi index, fecundity, egg diameter, hatching rate and time to hatching in the control
group (feed without enrichment of vitamin E) and exposed to 150 mg/kg, 300 mg/kg, 450 mg/kg feed of
vitamin E. Treatment of vitamin E levesls were significant (p<0.05) different with respect to time ripe
gonads, ovi somatic index, fecundity and egg diameter. Females exposed to 300 μg/kg feed of vitamin E
can increased time matured gonads 67 days, somatic ovi index 14.95%, absolute fecundity 13547
eggs/spaw, relative fecundity 98 eggs/g gonado weight and egg diameter 1.16 mm. But hatching rate and
time to hatching did not different between the treatments (p>0.05).
