What is the usual dose of hCG administered pre-ovulation? I have read 1500-2500 iu given iv. What is the usual route? Does it matter if it is IV or IM? I have seen the brand Chorulon, which is mixed up to 10 000 iu/mL. Is this brand used, or are other brands known to be more effective?

I have never given hCG IV -- always IM. Check with your VET for the proper dose. Internet sources are great for somethings, put I would NEVER rely on the Net for dose & route of medications info. If you are doing your AI at home, most vets understand and are willing to help you with meds, etc.

While checking with your veterinarian is always advisable before administering any drug, the standard dose for hCG in a 1,000-1,500 lb mare is anywhere between 1,500 and 3,300 International Units. The most commonly given route is intravenous, and it has been suggested that the (very) rare occurrence of anaphylaxis following treatment may be more commonly seen with IM use.
Chorulon is the most commonly used brand in North America.
It is worth while noting that overdosing with hCG may actually prevent ovulation rather than encourage it.
