其他摘要：ABSTRACT The quality of white shrimp Litopenaeus vannamei broodstock can be improved through the addition of astaxanthin and vitamin E in the diet. This study aimed to determine the effect of administration of astaxanthin and vitamin E with different doses in the feed on the maturity gonad of prospective Pacific white shrimp broodstock. Supplementation of 0 mg/kg feed astaxanthin + 0 mg/kg feed vitamin E (control/A), 500 mg/kg feed astaxanthin (B), 350 mg/kg feed vitamin E (C), 500 mg/kg feed astaxanthin and 350 mg/kg feed vitamin E (D), and 250 mg/kg feed astaxanthin and 175 mg/kg feed vitamin E (E) were applied in feed formulation. Shrimp was fed 2% of body weight three times daily at 06.00 am, 13.00 pm, and 20.00 pm. The result showed that the optimum dose for survival, specific growth rate and maturity level of Pacific white shrimp broodstock was obtained in the combination of 175 mg/kg vitamin E and 250 mg/kg astaxanthin. The survival of shrimp by that treatment was 100.00±0.00%, specific growth rate 1.07±0.26%/day, the first level of gonad maturity growth was reached at day 14 (19.45±4.81%), the fourth level of gonad maturity was obtained at day 41, spawning rate 33.33±8.33%, fecundity 87,000±2,000 eggs, and hatching rate reached 49.00±1.53%.
