[QUOTE="Dsth, post: 1613469, member: 38038"] I have about the same average of non responders. I do breed on signs of standing heat which ranges for 2 - 5 days. non responders do not get bred. I sync so they will cycle in 3 weeks with cows that did not settle from 1st breeding unless they have been open past 90 days. those cows will get a shot of lute at 10 days. I have changed my vaccination program this year since the vet said the live vaccine that I was using can cause cows to not cycle and reduce conception rated. I will see if the killed vaccine improves heat cycles and/or conception rates. I feel that my cows are above average in body condition scores so I don't think that factors into cows not showing heat.
