I am renting an Angus bull this breeding season that has good genitics. How long should I leave him in to breed out 21 cows? 60,75, 90 days? Thanks

Do you just mean preg checking?
I have a pretty good herd health program in my opinion
I agree with you about preg checking and that it would be the best bet. But let's face it, I would say the majority of commercial operations don't. (being that the majority is small scale operations) Every cow I ship for showing heat is preg tested at the sale. Its only a small fee and makes me sleep better knowing that I didn't send a good bred cow to slaughter.

That all depends on your goal. What is your goal?I am renting an Angus bull

Usually the length of the post-partum interval (PPI, time from calving to the first estrous cycle) is 45 to 55 days in beef cows. If cows are in good body condition at calving, then the PPI would be in the 45 to 50 day range and if in poor condition, the PPI would be longer. First -calf-heifers have a longer PPI compared to mature cows, about 10 days longer if she has no calving difficulty and is in good body condition. If cows are exposed to bulls (bull exposure) after calving, then the PPI is usually shorter by may be as much as 10 days shorter. It has been documented in beef cows that uterine involution is not completed by 20 days post-calving, but the uterus is back to its non-pregnant size by 30 days post-calving. Another 10 or so days is needed to complete uterine involution and be prepared for another pregnancy. I don't think many cows will come into heat (estrus) before 35 day post calving.
