This research investigates the effects of soy isoflavones on ovarian development in female Chinese mitten crabs, highlighting their potential as feed additives.

Key Points

This research aims to explore how soy isoflavones influence ovarian development in female Chinese mitten crabs.
Randomly assigned 192 crabs into four diet groups with varying soy isoflavone levels.
Dietary supplementation for 11 weeks with doses of 0, 32.51, 70.83, or 369.03 mg/kg.
Measured ovarian development through gonadosomatic index and vitellogenin levels in hemolymph.
Analyzed gene expression related to estrogen signaling and estradiol synthesis.
Supplementation with 32.51 mg/kg significantly increased the gonadosomatic index and vitellogenin levels.
Yolk granule formation was notably promoted at 32.51 and 70.83 mg/kg doses.
Soy isoflavones activated estrogen-related receptors and upregulated specific genes related to ovarian development.
High dose (369.03 mg/kg) did not show significant effects, indicating a U-shaped response.
