Abstract

The objective of this study was to diagnose sub-clinical endometritis (SCE) via endometrial cytology on day 42 after parturition and its impact on milk yield (305 days) of dairy cows (parity 2â€“4). Endometrial cytology was performed in 20 dairy cows, out of which 6 cows were found positive for sub-clinical endometritis. Mean number of polymorphonuclear cells was significantly higher in sub-clinical endometritis positive cows (22.00Â±4.77%) when compared to cows found negative for sub-clinical endometritis (2.58Â±0.76%). Subâ€“clinical endometritis positive cows had a significantly lower (P<0.01) 60 days milk yield as compared to subâ€“clinical endometritis negative cows. Similarly, cows found positive for sub-clinical endometritis (n=6) also had an average milk yield of 1772.38Â±111.22 litres which was significantly lower to those diagnosed negative for SCE (2392.34Â±65.16 litres).
