| Outline of Final Research Achievements |
To clarify changes in polymorphoneutrophils percent (PMN%) in the endometrium in postpartum suckled and non-suckled Japanese black cows, and to elucidate prevalence of mycoplasma injection in the uterus in the cows, endometrial cytology samples were collected using a small brush from postpartum cows. PMN% decreased significantly from 3 to 4 weeks postpartum, particularly in suckled cows. PMN% in Japanese black cows was lower than that in Holstein cows during the postpartum period. M. bovis was isolated from the uterus in one of the samples dairy cows. In conclusion, PMN% decreased as the postpartum period progressed, and suckling may affect changes in PMN% in early postpartum Japanese black cows. Although the prevalence of mycoplasma infection in the uterus seemed not to be high, the route of infection and its effect on fertility in the cows should be investigated in future.
