Our research
Research outline
The goal of our research is to reveal the regulatory mechanisms of reproductive functions in domestic animals (goats and cattle), and to utilize the basic knowledge for farm animal production. We currently focus on the following research projects using a multidisciplinary approach:
1. Neuroendocrine mechanisms regulating pulsatile GnRH release in ruminants
2. Physiological role of kisspeptin/neurokinin B/dynorphin in the control of reproduction in ruminants
3. Uterus
4. Heat stress
Our laboratory is located in the TOGO Field (University Farm), Field Science Research Center, in Togo town, where is 15 km away from Higashiyama Campus.
