Welcome Bolos1
there is alot of advice on this on the forum already you just have to do a little seaacrhing
same question was asked last week here is my reply hope its helpful
Key thing in Breeding is to mix horses of differing distances
I recommend inbreeding it has worked for me many times infact you an come up with freakishly talented horses doing that.
Once a stallion or Mare gets past 10 in the barn i usually retire them as they can produce a mixed bag after a while they produce more
rubbish but don't worry about the stats bars deteriorating in barn this will not effect the offspring.
My recommendation is you have good sprint breeding lines and you are looking for that derby horse look for mares that you DONT own
in the breeding barn get you sprinter to cover 1m6 up to 2m4 Mares look for the mares that have a serious career strike rate
you get some with stats like raced 10 times won 8 races and 4 g1 also cover every Mare over 1m6 up to 2m4 that costs over £100,000 to cover the more it costs to cover them the more chance they will produce better horses
Breeding with gamebred mares can be very hit or miss but all you need is to produce one good mare or stallion and it will begin your breeding empire over that distance. You will see which ones to keep you will get alot of rubbish breeding with gamebreds but you do get the odd few that are very good as stated you only need to produce a decent mare and stallion and that will be the start of your empire.

The stat bars Potential is by far the most important
what too look out for in inspecting your 2yos is you want the potential bar to be mostly dark green the above image explains this
Horses with alot of light green very rarely if ever fill there potential to fully dark green i usually dump these horses that have under 75% of
There potential as light green the more dark the more precocious the better.
if something has alot of light green bu the stats bars look strong send it to stud
as you can see with the image above this horse has very strong stats but i would never race it
as he will never fill out his potential to dark green but is a brilliant stallion in the making
So Dont be scared to send unraced 2yo to the barn they can surprise you what they produce
I Think i have covered it all best of luck get breeding with them Mare stayers it might take you a little while
but that Derby win is around the corner
An Idea of what to look for in breeding barn
also meant to say same for gamebred stallions dont restrict your self send some of your sprint mares to
gamebred stallions over 1m6 you can see below i have shortlisted a few you would look for in your game
the criteria you are looking for
