Outline of Final Research Achievements |
I investigated influences of stress and growth on metabolite levels in kynurenine pathway and other metabolic pathways in chicks by GC/MS metabolomic analysis. Heat stress increased levels of kynurenine pathway metabolites, kynureinne and quinolinic acid. Growth affected some interesting metabolites levels while changes of kynurenine pathway metabolites could not checked because the sensitivity of analytical method was not enough. Therefore, I established new analytical method to quantify various tryptophan metabolites including kynurenine pathway metabolites in chicks.

Academic Significance and Societal Importance of the Research Achievements |
ニワトリにおいて、成長やストレスとキヌレニン経路の関係は不明な点が多かった。本研究から、これらの関係解明に向けて有用な基盤情報と分析系を得ることができた。これらを用いた更なる研究は、ニワトリにおける生産向上に係る生理機能の解明に向けて有用である。今後、関連する研究成果の蓄積から、食糧自給率の改善が望まれる我が国における鶏卵や鶏肉の生産に資することを目指す。
