OK, I’ll play too.
My costs are a whole lot less than that example.
Grain- $40 Max per month (-$10)
Hay- about $20 per month, if that, because we grow our own (-$50) (-$960 in feed costs)
I’m sure feed costs are much less than that, too, because once the foal is weaned and the mare is bred back, she goes out on pasture where hay and grain are fed only when the grass isn’t sufficient to meet nutritional needs- generally winter only.
Shavings $5/mo. - the only cost is the fuel to go get them (-$960 in shavings)
Farrier about 10 trims in 16 mo, $15 ea (-$298 in farrier costs)
Yearly vet costs not including breeding- under $100 (float teeth, shots) (-$150 in vet costs)
Mortality insurance- I don’t think so. (-$550)
Indirect costs per horse (I have about 15 total): water $3 (-$4), utilities $7 (-$18), insurance $7 (-$71), hired labor- yeah, right. (-$85) Total -2848 for 16 months.
Just those differences in expenses add up to $5766. $10,507 less $5766 = $4741
If you want, you can add in about $1000 for that 16 month period to cover the foal’s portion of the mortgage,taxes and tractor and equipment payments, even though that also includes the roof over my head (no I don’t have much of a mortgage, and taxes are cheap here). That still only brings the total cost- if breeding and inspection costs stay the same- to $5741.
If you stand your own stallion and live cover, you can subtract another $2200.
Just because it costs one person $10,000 to get a foal to weaning age, doesn’t mean it costs that much for everyone.
