I feel like I've been on here long enough to know this by now but I don't :\">

So do mares gain a little bonus with each day, every 10 days (just an example) or just after the 30 days?

I have well over 300 mares to breed each year and have to try and do it all in one 60 slot pasture. I've been trying to save up the cash to buy myself a new pasture but I haven't been able to yet. My current mares have been in there for 11 days and I'm anxious to breed (1. because yay babies and 2. because I've still got 3 more groups to filter through)
I'm trying to better my horse quality by using the pasture bonus as much as I can. I'd like to know if I need to select 2 groups a season to get a bonus on or if I can get away with alternating them for said amount of minimum days
