[QUOTE="Katpau, post: 1546498, member: 9933"] I usually AI a portion of my herd each year using fixed time synchronized protocols. I had been giving 6 to 7 cc of Lutalyse as was recommended to me. In 2017 I switched to the new 2cc dose product. I had 13 out of 14 cows show heat and all 13 of those who showed heat, settled AI. I went ahead and used the 2 cc product again this year because last year was my highest percentage of successful AI ever. We usually settle somewhere between 60 and 80% with synchronization and fixed time breeding and there are usually a few that have not yet shown heat by the scheduled time to breed. Last year 92.9% showed heat prior to scheduled AI and 100% of those settled and gave birth to an AI calf. That was likely mostly dumb luck, but I gave some credit to the new concentrated Lutalyse. Did your embryologist say why you should not use the more concentrated Lutalyse? [/QUOTE]
