[QUOTE="3waycross, post: 1314960, member: 6713"] I am hoping to start a constructive discussion on increasing breedback success on first calvers. Especially where it pertains to AI'ing them for the second calf. This issue plagues me virtually every year and I would like to hear from anyone who has had ongoing success in getting an early breedback in this situation. My cows are in a system that in my mind should lead to a decent percentage of AI success but it doesn't seem too. We keep the first calvers separate for most if not all of the winter. They get better feed than the main herd, including cake and brewers barley leftovers from a local brewery. They also get the best hay. After they calve this is continued and the protein levels are even upped to some extent. They are still separate until they are brought in and protocalled for AI. We then try to always AI them on standing heat as much as possible and then before turn out the remainder are all time bred. The problem is the 2yr olds just don't seem to want to catch like the older cows. I am at the point of giving them the AI protocol and just turning them out with a bull, so as to not lose a month going in on them for that second calf. As it stands right now I have 3 first calvers who calved 3 to 4 weeks before the older cows last year and are at least 2 to 4 weeks behind them now. [/QUOTE]
