[QUOTE="Ky hills, post: 1592236, member: 24816"] For what it's worth, I would say that the 65 or whatever % conception from TAI was pretty good. I quit AI because that is the desired protocol these days and our results over the course of 4 or 5 years was anywhere from 60 down to 30, and one year 10 head of registered Angus cows and heifers was a total 0. These cattle are not the best in the world like the OP, and don't have the best of the best of everything, however I am confident that they don't lack for much. For a reference, 25 or so years ago we were AI'ing registered Charolais, using the conventional 2 rounds of Lutalyse and watching them at night and morning starting two days after the last round of Lute, and then breeding approximately 12 after observed standing heat. Those cows were 1400-1800 lbs, and in good condition, but admittedly my mineral program at that point was a joke by todays standards. they got different color salt blocks depending on the season, and loose Hi mag mineral during the late winter, and spring. We managed to get as much as 90% conception with them, most of the time, 80% would have been very low %. I have never seen those results with the cidrs, and TAI, even with a far better mineral and nutrition regimen. For a registered breeder, I get where AI is beneficial, but from a commercial standpoint where I am now, I think it is a waste of my time and money. If I have to maintain cleanup bulls for 40% or more then I just as well let the bulls do all the work, and have a more uniform calving season. It may be not yield as many calves in a short period, which is a good thing, but that bull has a far better chance of getting them bred 1st time, and if not most are by the second. After the AI fiasco our calving was spread out into the summer. After a couple of years of natural service it is getting back on track. I do know several commercial outfits that AI, but I think they likely do it pretty early before it gets too hot. [/QUOTE]
