In particular, synchronized ovulation with timed artificial insemination should result in more pregnancies because essentially all cycling cows can be inseminated near the time of ovulation. Without this procedure, they would be inseminated only if detected in oestrus. Although the percentage of inseminated animals becoming pregnant will not improve, the high number inseminated will result in more pregnancies. In a Florida study, Holsteins subjected to synchronized ovulation with timed insemination for the first insemination had more pregnancies (16.6%) at 90 days postpartum than did controls (9.8%). In another study, pregnancy rates at 90 days were 34.3 O/Q for cows given the synchronized ovulation with timed insemination treatment as compared to 14.3% in controls.
