The aim of the present study was to analyse the effect of the subclinical endometritis on the postpartum period and its effects on the reproductive efficiency of cows in Argentina. Two hundred and seventy four cows from four dairy farms were used in this study. Cows were kept/maintained on fed grazing with supplementation diet. The diagnosis of subclinical endometritis was carried out by endometrial cytology with ≥ 5% of polymorphonuclears neutrophils. Positive cows to subclinical endometritis had lower reproductive performance than negative cows. They presented lower pregnancy rates in the first breeding, higher artificial inseminations per pregnancy, and longer calving-pregnancy periods in comparison with healthy cows. Subclinical endometritis has a negative effect on the reproductive performance of the dairy cows and consequently in the dairy farms finances in the animal population studied.
