Abstract
The objectives of this study were to investigate the relationship between uterine fluid and endometrial cytology (EC) followed by study of association with uterine involution, calving to first ovulation interval, and conception in dairy cows. On day 43 post-partum, 23 dairy cows were grouped, on the basis of EC, as having low (<10%) or high (>10%) polymorphonuclear cells (PMN), and the quantity of uterine fluid was assessed by ultrasound. Uterine involution was significantly earlier in cows having low PMNs as compared to high PMNs (24.1 vs. 31.7 d). The interval from calving to first ovulation was significantly shorter in low as compared to high PMN cows (23.4 vs. 30.7 d). With the increase in the quantity of uterine fluid, PMNs also increased from 6% to 21%. The mean interval from calving to ovulation was longer in primiparous cows with high PMN (33 d) compared to that of primiparous and multiparous cows with low PMN (24 and 22 d, respectively). Cows that had uterine fluid on day 43 post-partum had fewer days open than those with no uterine fluid (107 vs. 130 d). So, the conclusion may be drawn that transrectal ultrasonography and endometrial cytology, when combined together, on day 43 post-partum, have diagnostic value in the assessment of uterine inflammation.
