[QUOTE="SPH, post: 1482428, member: 20580"] We've done the "forced breeding" with synching for AI and had no luck with it. Unless you observe the female in heat after you sync I wouldn't waste a straw of semen when you aren't positive she is actually in heat. I guess it depends on what your breeding program is too. We sync heifers and early calvers for AI for 1 heat cycle then turn everything out with the herd bull after that because we want to keep a tight calving interval. If we see them in heat we do AI and hope they stick, if not the herd bull will likely get them on the next heat cycle. We do AI sync for around Feb 15-20th calving date so if they don't stick to AI they still will probably have a natural date in early to mid March. If they don't show heat in the AI group we wont waste a straw and assume the herd bull will get her once she cycles. This is where the value of a good herd bull comes into play because while you can add some outside genetics through AI you shouldn't be scared to use your herd bull either. [/QUOTE]
