Overview

This research evaluates gamma-oryzanol's effects on bovine oocytes, revealing improvements in oocyte quality and antioxidant enzyme expression.

Key Points

  • Gamma-oryzanol treatment significantly increased metaphase II oocyte rates in heat-stressed bovines.
  • Oocyte maturation resulted in greater cleavage and blastocyst rates in the treated group compared to controls.
  • The antioxidant upregulated crucial transcripts associated with heat resistance in matured bovine oocytes.
  • These findings indicate enhanced reproductive efficiency in dairy cattle under heat stress through antioxidant supplementation.
