Following similar ideas to Mareslave - here in Alberta I’m roughly at:
To get pregnant:
Using fresh semen and getting pregnant on 1st cycle:
around: $4382 (round it up to $5000 for any unnoted extras I forgot) based on the following figures:
stud fee: 1500-2500
Collection fee: $300-450
Fed Ex shipping: 300-600 depending on distance
mare board at vet’s facility $21/day x about 5-7 days $147; more if she has a foal at side already.
insemination: 500
Oxytocin x 2 days, $5 (if I do myself)
Ultrasound preg and twin check: $65
Secondary preg check for preg status and double-check against twinning: $65
Travel (diesel costs) to said U/S checks: $25
Add more to this cost if she takes a 2nd or 3rd or even 4th cycle to conceive and maintain a pregnancy past 30 days.
Foaling out - If mare goes to vet to foal out (recommended in your case since she’s not at your home for 24/7 watch):
Vet fee, including newborn check: $800
IgG draw: $45
Subsequent well-baby checks: 80 x 3 = $240
Travel to vet for baby checks: $25 x 3 = $75
hoof care: 40 x 6 trims (at 4 weeks apart) $240; more if baby needs trims more frequently for correction.
Vaccines/worming: About another $200-300.
TOTAL: $1700 (round on up to $2000) TO WEANING.
So a basic foal to 6 months of age without any difficulties from either mare, delivery, or growth results in a cost of $7000 per foal.
Does not include Foal Growth Kibble in that cost.
Board is extra - much extra and will exponentially increase your costs.
Frozen Semen - Change the stud fee to a per dose fee to between $500 - 1500 depending; increase the insemination to $600-800 because it requires more monitoring.
This is assuming (not likely) that everything happens just tickity boo; otherwise, anticipate to double, perhaps even triple your costs.
And factor in a possible 50% loss (losing either the mare or foal) to a 100% loss (losing both mare and foal) if things go wrong shortly before, during or shortly after delivery. Which can and does happen.
In the grand scheme of things, mares collectively around the world are slipping their pregnancies all the time, so that’s your major loss right there.
Frankly, if you have to board, you are better off buying a weanie from a breeder because your boarding costs put your foal value at around $10-15,000 whatever your board is for 18 months. That foal had better be smashingly spectacular to justify this.
While you are stating you “already pay board” for the mare already, the board is a very real expense and is part of your foal production cost. You are paying that boarding facility to properly feed and house your mare so your mare can grow your baby. Therefore, it IS a cost towards your foal.
