While intrauterine fluid (IUF) is observed as mucous in healthy mares during estrus, the presence of IUF diestrus an indicator endometritis. Mating induces endometrial inflammation mares, called mating-induced endometritis, that disappears within 1–2 days after mating. On other hand, it also known remaining beyond 12 hr mating can cause persistent inflammation, bacterial growth, and decreased fertility. This study aimed to investigate relationship between cervical bacteria before Mares were classified into three groups based on degree IUF: Grade 1 (G1), neither nor echogenic lines at inner lining uterus; 2 (G2), small amount (<0.5 cm diameter) or cavity; 3 (G3), obvious (≥0.5 diameter). The positive culture rates G1, G2, G3 15.8% (n=6/38), 25.9% (n=7/27), 31.8% (n=14/44), respectively, did not differ significantly groups. After mating, 18.2% (n=2/11), 56.1% (n=23/41), 72.3% (n=34/47), respectively. higher G2 (P<0.05) (P<0.01) compared with G1 mares. These results from suggest only but those a cavity are risk
