**Posted this on Forest server but posting here too because I know there are a lot more boosted foundation breeders over here!**

I have a few questions! I need some assistance restructuring my mare AFPT culling system. I used to breed C/Yellow foundation stock and used the criteria listed below. I now currently breed from primarily A/Blue foundations with one line being from B/Red foundations. I really want to get stricter with my culling because I continuously run out of pasture space. AFPT has always been difficult for me to utilize for culling because of my stock being boosted and me not knowing what to make my cutoff.

Ideally I would like two separate criteria for AFPT based on the foundation breeding level. So the below list is for C/Yellow (perfect foundations) and I need to edit it to fit B/Red (Ex Pro/Perf foundations) and again to fit A/Blue (boosted foundations).

This is what I was using when I was breeding from C/Yellow foundations so how should I tweak this to fit my A/Blue lines and B/Red line? (I copied this list from Ammit several RL years ago from a post she commented on pertaining to PT and AFPT).
- F 9.9
- 2G 10.3
- 3G 10.7
- 4G 11.1
- 5G 11.6
- 6G and up 12 or higher

So here are my questions:
1. Using the criteria/format above, what are reasonable AFPT goals to strive for in each generation for my current boosted and ex pro/perf breeding lines?
2. Do you cull stallions by AFPT? If yes, do you do it after at least 10 foals? 25? A different number?
3. How often do you check mare AFPT. Do you check and cull after 3 foals? Do you recheck every mare every year? What is the best way to utilize this culling method? My idea was to currently go through all my mares 6+ with 3 or more foals and cull based on the new criteria and then for the younger/future mares, wait until they are 6yo and have 3 foals and cull only as 6yos.


I am working on trying to create my own lists but would love some input from other experienced players! Thanks in advance for any help!
