Abstract:

Endometrial histopathology was studied in 16 postpartum dairy cows. Endometrial biopsy was taken from the all experimental animals, to study the histopathological changes of the uterine endometrium. 8 cows in group I (n=8) on day 2 postpartum and were treated with an intramuscular injection of 5 mg methyl ergometrine maleate. All the cows in group I were inserted with Controlled Internal Drug Release device (CIDR) on day 45-55 postpartum intra-vaginally. Whereas 8 cows in group II (n=8) were selected at day 35-50 postpartum and supplemented with TANUVAS mineral mixture and treated with ovsynch treatment. In group I cows on day 10 postpartum, showed involution process, with mild neutrophilic and mononuclear infiltration. When compared to day 10 postpartum, the regenerative changes of epithelium and endometrial glandular activities were predominant on day 30 postpartum. In group II cows before treatment (at the time of animal selection), 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. After treatment (at AI), 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 first service, second service and overall conception rates observed were 22.22, 33.33 and 55.55 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 postpartum cows positively correlated with the well healthy endometrium lining and glandular development.
