[QUOTE="CattleMan1920, post: 1549231, member: 37967"] We’ve been pushed hard to synchronize and to use Lutalyse by people we do business with, which we have not done. Instead we give the cow everything she needs from a nutrition standpoint and WAIT...we wait for the first heat post calving, then AI on the second heat, and it’s been a successful strategy, with most settling on first service. In this day and age we all want to push things to happen faster and on our schedule as well, but nature has another plan. We have no issues whatsoever with people who sync and use lutalyse, that’s their business, and we understand why time is of the essence, but with that said we’ve not had any success when we rush things. We have AI’d some cows 5 times before they settled, but, and a big BUT, we are going for a particular animal, we would far rather have a son or daughter of SAV President for example than a son of a cleanup bull, and we will wait for that calf. The value of one over the other is daylight and dark. Not to mention how that animal will influence the herd for years to come. As it’s been said here before, we use a sophisticated heat detection system, and it monitors all our females (under 1 year excluded) 24/7, and one thing is for sure none of our animals, who are in excellent condition, come into heat on a rigid fixed schedule, they come in when they come in, and when they come into heat they get bred AI. Some have heats for 4-6 hours some 20-26 hours, some are intense, some are hardly noticeable, but all are very different from one another. Some of our best calves have come from cows that were very difficult to settle. The only time a bull is used is if we feel that it has become futile, and they usually get the cow settled. This plan is not for a producer going after numbers but it works well if you must have progeny from a certain sire. We think it’s worth the wait.
