My daughter's 4 year old nubian has had a date with a buck in the next county for two months now. Since we always had a buck on site to breed her, I never noticed if she had regular heat cycles or how long they lasted. I saw her in heat on October 6, and have been watching her like a hawk every 17 - 25 days for signs of heat so I can haul her to the buck. As far as I can tell, she either has not gone back into heat, or is in heat only a few hours each time. I am thinking of using lutlyase, 1 ml today, and 1 ml in 11 days to "catch" her. The only way a she could have already bred would be if another buck jumped a few fences, then jumped back again. Does this sound reasonable?
