[QUOTE="KNERSIE, post: 366249, member: 4353"] I have used two straws on those, I'm not quite sure cases. Once when I suspect they were about 6 hours into standing heat and again 12 hours later. I have only done this when I wasn't sure what I have observed was in fact standing heat. The semen I use is too expensive to make this standard practise. So far they have all settled, but I have done this only on about 6 heifers and 1 cow. This makes me think there might be something in this, but I am sure it has more to do with semen being there and alive and swimming for a longer period making the timing less critical than with the volume of sperm.
