Per Ammit (as of September 2017):

How things work on the lb for top stud and mare have changed slightly so I wanted to give a rundown.

Anytime you look at a horse's page it checks them for foals and then updates their foal score if they qualify for the LB. It zero outs the foal score for any horse that does not qualify.

To qualify for the LB a horse must have a living foal that is less then 3 years old (that is foals born the current or prior year).

Stallions must have a minimum of 10 foals, mares a minimum of 3.

The act of breeding a horse will also trigger a foal score update on both sire and dam. You do not need to pull up the pages of breeders from today on to get on the LB.

Foal scores are not dropped at the end of the season. That means horses that no longer qualify for the LB are not auto kicked off. To force an update just open that horse's page and they will be removed.

I think it may be a combination, but don't quote me!

It is also the case that stallions and mares that are higher up in generations are going to throw foals that have higher PT scores and better breeding ability than Foundations. Most of the horses you see on the top of the producer leaderboards will (usually) be higher generation horses.

Add in the fact that upgraded accounts can, via embryo transfer, get 3-5 foals from a mare per season, and people can pick and choose the foals with the higher PTs and sell the lower scoring foals back to the game thus keeping the parents AFPT and foal count pretty high.
