Introduction
In dairy and beef cattle production, the management to maintain high reproductive performance is essential. However, in the current reproductive management of cattle, various problems have arisen such as, "difficulty to find estrus that is essential for artificial insemination", "the conception rate of artificial insemination and embryo transfer has not reached a sufficient level" and "occurrence of pregnancy loss after pregnancy establishment". There are many challenges to improve reproductive efficiency.
In laboratory of Theriogeneology, we are conducting research to obtain findings about reproductive physiology that can contribute to improving the reproductive efficiency of cattle. These studies focus on approaching challenges from a physiological perspective such as, "what kind of physiological abnormalities are involved in the reproductive problems of cattle", and "what kind of treatments are effective to the reproductive problems that relate to the physiological disorders", etc. We believe that elucidation of the physiological mechanism is essential for improving the reproductive efficiency of cattle.
Based on this idea, we are conducting the following research with the aim of improving the reproductive efficiency of cattle.
① Ovarian physiology (morphology and function of follicles and corpus luteum) and related reproductive endocrine
② Elucidation of the physiological mechanism involved in the establishment of pregnancy in dairy cows (oviduct and uterine function, immune function, etc.)
③ Research on timed-artificial insemination program
