Endometrial histopathology was studied in 16 cows at 35-50 days post-partum period including 8 cows treated for RFM (Group I) and 8 normally calved cows (Group II) before and after oestrus induction with Ovsynch treatment. In NC cows, the uterine endometrium was intact. Multiple glandular acini and congestion were noticed. Uterine subendometrium showed few glandular acini lined with single layer of epithelial cells. Solitary glandular acini lined by multi layers of epithelial cells. Histopathology of the uterus in the RFM affected cows before treatment reveals discontinuation of the endometrial epithelial lining. Complete loss of epithelial lining associated with degenerative changes and atrophied glandular acini and loss of epithelial cells in the endometrial glands. After treatment, NC cows showed active proliferation of epithelial cells with intactness of endometrium. Uterus showed normal architecture of subendometrium with glandular acini. The intact endometrium with hyperplasia of endometrial glands was observed. The histological changes in RFM affected cows after treatment were highly impressive. Proliferations of epithelial lining of endometrium and engorged blood vessels with active glandular acini of the endometrial glands are evident. The first service, second service and overall conception rates observed were 25.00, 50.00 and 75.00 and 37.50, 50.00 and 87.50 per cent in Group I and II, respectively. Hence it is concluded that increased conception rate after ovsynch treatment in post-partum NC than the RFM affected cows positively correlated with the well healthy endometrium lining and glandular development.
