Research Description

Milk productivity of dairy cow has been increased rapidly during the past half century. On the other hand, decreasing reproductive efficiency of dairy cows, in particular conception rates and pregnancy rates, is a major problem in modern dairy industry. For solving these problems, it is necessary to clarify the effects of nutrition and metabolic status associated with high milk production on the hypothalamus-pituitary gonadal axis and to develop effective therapeutic and prevention methods for reproductive diseases in dairy cows. From these points of view, I am currently conducting several experiments on dairy cows and Shiba goats (an experimental model animal).

Main research theme
1. Understanding the association between nutrition, metabolism and reproduction in dairy cows

2. Developing new therapeutic and prevention strategies for estrus and ovulation failure

About TUAT's tenure-track program

The tenure track project of our university has really robust supports for young researchers by providing research start-up assistance fund and reducing burden of faculty tasks and classes. I am very grateful to have a big opportunity that I can concentrate on my research activities.

Future aspirations

First of all, I will steadily progress my research so that I can get sufficient outcomes in my research during 5-year tenure track period. Also, I think that one of the major attraction of this position is that I can be involved in education of undergraduate and graduate students. I will work hard on teaching students along with my research, and I would like to make my laboratory full of vigor.
