Tried 5 times to settle a mare to a great stud last year. Studs semen quality was less than 30%. Stallion owner had it checked this year, and says it is shipping at 45%. This stud is local and I will be there for collection and taking the semen back to my house for insemination. Is 45% count/quality good enough to get the job done?

It's not the % progressive motility that counts, it's the total number of normal progressively motile sperm that make the difference.
You want an ideal dose of 500 million normal progressively motile sperm in an insemination dose, but there has been shown to be no significant reduction in pregnancy rates until numbers fewer than 100 million are inseminated assuming that the mare is close to ovulation at the time of insemination.
Consequently, if you are shipped 1 billion sperm in an insemination dose (which is standard), and you have only 10% progressive motility, you are still very likely to have good pregnancy rates. It is therefore important to perform an evalaution upon collection and ensure that sufficient sperm are being sent. If that is done, you should be fine as far as the stallion end of things is concerned.
