Implication

Integrated analyses demonstrate enhanced growth and reproductive potential in Macrobrachium rosenbergii with optimal dietary cholesterol levels.

Key Points

  • The study aims to explore how dietary cholesterol impacts growth, health, and reproduction in Macrobrachium rosenbergii.
  • Investigated growth, metabolism, immunity, and reproduction using metabolomic and transcriptomic analyses.
  • Compared various cholesterol levels (1.0, 4.4, 8.2, and 10.7 g/kg) in prawn feed.
  • Measured parameters such as weight gain, yolk granule density, alkaline phosphatase activity, and estradiol levels.
  • Prawns fed 8.2 g/kg cholesterol showed significantly greater weight gain than those fed 1.0 g/kg.
  • Larger secretory cells and visible storage cell morphology were observed at higher cholesterol levels.
  • Yolk granule density increased with higher diets, particularly above 1.0 g/kg.
  • Alkaline phosphatase activity decreased as dietary cholesterol increased.
  • Estradiol content was significantly higher in prawns fed 4.4 and 8.2 g/kg compared to 1.0 g/kg.
