Forty\u2010five cows of 5\u2009\u00b1\u20091.6\u2009years were selected. The Jsynch treatment consisted of the application of an intravaginal device plus benzoate; on day 8, the device was removed and PGF2\n                    <jats:italic>\u03b1<\/jats:italic>\n                    , estradiol cypionate plus eCG was applied, and the FTAI was performed at 48\u201352\u2009hours after.

The diagnosis of pregnancy was determined by transrectal ultrasound 45\u2009days after the FTAI. The Jsynch (39.1%) and conventional (39.1%) treatment showed higher pregnancy compared to the Ovsynch treatment (21.7%) of pregnancy. The presence of crystalline mucus at the time of the FTAI was significantly associated with pregnancy.
