AB The aim of this study was to evaluate the influence of subclinical endometritis (SE) on the reproductive performance of dairycows. Ninety-four dairy cows of parity 1 to 8, distributed in 25 herds, were examined once between 30 and 45 days in milk usingtransrectal palpation, vaginoscopy and ultrasonography. A cytological sample of the endometrium was taken only from cows withan apparent healthy uterus (n=65). Serum glucose, total cholesterol, triglycerides, non-esterified fatty acids, β-hydroxybutyrate,total proteins, albumin, urea and hepatic enzymes were analyzed. Reproductive indexes were recorded during the next 11 months.Endometrial cytology was considered indicative of SE if percentage of polymorphonuclear neutrophils was superior to 5% of allcells present in the smear, except erythrocytes. Results indicated that 14.9% of the cows sampled for uterine cytology had SE, andthat healthy cows become pregnant significantly before than those with SE (hazard ratio=2.35; 95% confidece interval: 1.05-5.3).From all the metabolic and productive variables analyzed, only triglycerides affected negatively to reproduction; serum albuminconcentration, body condition score and milk production had positive effects on the reproductive performance. In conclusion, ourresults indicate that SE has a negative impact on reproductive performance and uterine cytology is necessary to diagnose it sincealmost 15% of the affected animals were not detected by other diagnosis methods
