| Outline of Final Research Achievements |
The aim of this study was 1) Search clinical biomarkers for evaluation of quality in bovine ovarian function, and 2) Clinical trial in field on the evaluation of reproductive performances by them with anti-Müllerian hormone (AMH), which was the clinical biomarker for evaluation of quantity.
In the result, some blood chemicals (total cholesterol, LDL, aspartate aminotransferase, and phosphorus) correlated with blood AMH levels. Moreover, their blood levels were differed among farms which reproductive performances were unlike. In conclusion, the combination of some blood chemicals which related to liver function and lipid metabolism and AMH may be able to evaluated not only ovarian function but also reproductive performances in farms.

| Academic Significance and Societal Importance of the Research Achievements |
繁殖効率の改善には、繁殖能力の高い個体の選抜や増産、科学的根拠に基づいた繁殖管理（診断、治療、評価など）が必要で、本課題で開発するバイオマーカーによる卵巣機能の質と量の両面をカバーした評価法は、ホルモン剤に依存しない食の安全・安心に寄与した新しい繁殖管理技術として国内外の家畜生産に速やかに受け入れられ、さらにウシと同様に繁殖効率が求められるブタやヒツジなどの産業動物への応用に期待が持てる。
