We asked AI about Captains Quarters

[Harness the King]

Bred our mare 4 times with no luck.  Vet looked at seven and found minimal motility

[captaintreacherous]

what was the mares name?


did she foal last season?

Comparing cattlewash and bulldog to Captains quarters is ridiculous. They had small first crops because they were still racing and bred a small book of mares by design. CQ has fertility issues is what we're telling you. Cattlewash and bulldogs fertility has never been called into question

I have many many year of breeding stallions….some great ones and some not so good. I’ve seen many studs come and go….some with lots of hype.
In my expert opinion I think Captians Quatrrs will be ok, a sire stake type that won’t get a ton of mares….i hope he does well. He was a nice horse with good connections….and what do I know. I’ve been wrong about new studs before.

I was looking at a few others and thought Captain Albano
was the one I would go with but unfortunately
failed the fertility tests.
Still racing spectacular.

I also considered Legendary and/or Nijinsky..but i
am really concerned about New Jersey breds at this point.
Meadowlands goes down and where do we race?

Nijinsky, a bettors delight...but he was a super horse on the
track...but not a top 2 year old.

Others would be the flavour of the month types
Cattlewash and bulldog..who are getting the best mares.

and have produced the best 2 year olds so far..which figures.

Tall Dark Stranger still may come around.

tricky game...but from what i am hearing

there will be plenty of fast mares going to Captains Quarters

for his second season.

My friend bred one fast 2 year old 1:51 broodmare
and she is in foal to Captains Quarters.
that will be her first foal if all goes well.

Also matters what your goal is...

If I am selling in the sale..I may go with cattlewash or
bulldog..already proven.

If I am racing ..you almost have to gamble on Captains
Quarters...
first and/or second crop.

Looks like some serious upside.

There isn’t a single published “first-year conception rate” specifically for first-time Standardbred stallions, but a reasonable benchmark is:

About 60% pregnancy on the first breeding cycle is a strong general benchmark under commercial conditions.


With repeated breeding over the season, roughly 70-75% of mares may become pregnant when the stallion, semen, mares, and management are all good.
Live-foal rates are lower, around 70–75% in a large commercial Standardbred dataset.

A first-year stallion can perform below those numbers simply because he is inexperienced, semen collection and handling are still being optimized, or he is bred to a large number of mares. The quality of the mares and the breeding system often matter as much as the stallion himself. A recent study of nearly 4,000 Standardbred mares found a 61.4% first-cycle pregnancy rate, 84.7% end-of-season pregnancy rate, and 73.1% live-foal rate.

So, if you're evaluating a new Standardbred stallion, I would not judge him too harshly from a first season unless the conception rate is consistently poor after accounting for mare quality, semen type, timing, and veterinary management.
