ThemeHow are metabolic hormones of ruminant animals different from monogastric animals? Reserch and application
|Field||Animal Nutrition and Metabolism, Endocrinology and Metabolism|

Unlike monogastric animals, ruminants are characterized by ruminant stomachs. They differ not only with respect to nutrition, such as in digestion and absorption, but also with respect to metabolism. Metabolic differences affect biological regulation, and there are different mechanisms of reactions and responses of the endocrine and nerve systems. I aim to study such differences and make use of them in applications.
In recent years, a new peptide hormone that has various effects has been found through gene analysis, and research on the mechanism and results of its action is urgently needed. However, the progress of research is slow, not only on the action of the hormones, but also on their application to nutritional mechanisms, such as the promotion of animal growth, and emphasis must be placed on this point.
Therefore, it will be necessary to first develop a technique for measuring these hormones using enzyme immunoassays, time-resolved fluorescence, and other methods that involve the induction of competitive reactions of labelled antigens using immuno plates solid-phased with a second antibody and the measurement of their absorbance after color-labeling using enzymes, as shown in the photo.
List of current research topics
- Study on the effect of pituitary adenylate cyclase activating polypeptide (PACAP) on metabolic hormones in ruminant animals
- Establishment of metabolic hormone mesurement techniques

I was born in Toyama Prefecture. I’ve been working on elucidating the secretory mechanisms of metabolic hormones, including of growth hormones, in ruminants. I intend to deepen my consideration of metabolic hormones in the future.
