The puerperal uterine soundness is essential for the re-establishment of postpartum ovarian cyclicity and next pregnancy. Normally calved 36 healthy Holstein Friesian crossbred cows aged between 2nd and 5th lactations were selected immediately after parturition. Day of parturition was considered as day 0 of the experiment. All the selected cows were randomly and equally divided into 4 experimental groups viz., group I, II, III and IV (control). The endometrial tissue collected on day 10 and 30 postpartum in all the four groups through Albuchins’s biopsy catheter was processed by paraffin technique and sections were cut and mounted on coated slides for immunohistochemistry. These slides were tested for immunological expression of CD3+ and CD20+ cells to identify T and B lymphocytes. Immunohistochemistry of endometrium showed mild expression for CD 20+ cells in groups I, II and III and moderate expression of CD20 +ve cells in control cows on day 10 and 30 postpartum. None of the cows in experimental and control groups expressed positive for CD3+ cells.
