Trinity has it right. Using my vet’s fees (he does packages), expenses are roughly:
Fresh semen:
Stud fee (including booking) $1900
$150 for collection
$150 for shipment (could even be more depending on distance)
$400-600 vet fees for mare U/S, hormone shots, insemination, and followup U/S with oxytocin.
$2600 to 2800 for the first cycle.
Second cycle:
$150 for collection
$150 for shipment (or ++)
$400-600 Vet fee
$700-900 for the second cycle.
Assuming she took by second cycle: $3300 to $3700 depending on your vet fees.
Frozen:
You buy 2 doses at $750 each, ship all at one time = 1 shipment cost.
Semen 1 dose $750
Shipping $150
$600-800 mare treatment/insemination by vet
$1500 to $1700 first cycle.
Second cycle:
$750 semen (no shipping)
$600-800 mare insemination
$1350 - 1550 for second cycle.
Assuming she took on second cycle: $2850 to $3250, depending on vet costs and what the mare required.
Pregnancy check U/S = $65 and I have this done on day 14 twin check, then again day 30 and another day 55 to be sure it’s progressing.
Some vets charge extra for board. My vet does not, but then I live right nearby and provide my own hay and can zip over and feed her myself, so he doesn’t charge me board costs. If your vet charges board costs, then add that to your daily tally.
Depending on the mare candidate, frozen can be cheaper… or alternatively if you have a difficult mare, then fresh is definitely the cheapest way to go because your treatment and vet costs start to really add up. If you have a mare who tends towards a lot of fluid, then I would never use frozen on that mare.
The best response in this type of question is: Choose your mare wisely.
If she is simple, straight forward, doesn’t pool fluid, clears fluid post-insemination easily, is readily fertile and fairly young, then frozen could be the simplest and cheapest alternative.
If she has any complications whatsoever - meaning she requires extra estrogen and oxytocin prior to breeding because of constant fluid, constant vigilence with regard to infection elimination and a couple days worth of post-insemination flushing and diligent oxytocin protocol, and she’s older, or have proven to be befuddling in the fertility department, then fresh is the best and only alternative for her.
Obviously, a maiden, you don’t always know if she is easy or difficult. So, you try with easy and have a Plan B fresh backup if she turns out to be difficult.
