Stallion Incentive Program (SIP)
Once a stallion has 5 non-gelding, non-steeplechase foals on the ground, he can be submitted for enrollment into the incentive program, which can be found on your Stud Services page. If the average of those 5 foals is over 35, he will be granted Bronze level SIP. If the average of those 5 foals is over 40, he will be granted Silver level SIP.
Once a stallion has 10 eligible foals on the ground, he can apply for an updated enrollment. If his foal average is 30+, he will be granted Bronze status. If his foal average is 35+, he will be granted Silver status. If his foal average is 40+ he will be granted Gold status. You can apply for an upgrade with any stallion who has new foals on the ground who may improve his status, but you cannot earn a Gold status until a stallion has at least 10 eligible foals.
Platinum is the highest and rarest so only the best studs will earn it. It is unique from other SIP levels because there are two ways you can earn it and also because it factors in Improvement Over Dam (IOD). A horse will earn Platinum if they have a 45+ AFP with 10+ IOD or 40+ AFP with 15+ IOD. You can test a horse for Platinum once they have at least 15 eligible foals.
A Bronze level certification will award your stallion 2 additional foal slots. A Silver level certification will award your stallion 4 additional foal slots (or 6 if he skipped bronze). A Gold level certification will award 6 additional slots (plus additional slots for skipping bronze/silver). The total foal slots that can be earned through the SIP is 12.
The higher level a stallion is within the SIP, the higher his suggested stud fee will be. Stallions who are not proven or who have proven too bad to be accepted will have substantially lower stud fees than studs at the Silver or Gold level. It is always in your best interest to only stand stallions who are truly stud quality because not only will they have more foals and better foals, but they will bring in more money from stud fees and yearling auctions.
If your private stallion (not eligible for public studding) earns a Silver or Gold status in the SIP, he will become eligible for public stud. Because they have a limit of only 5 foals to begin with, it is imperative to make sure you test them before any of the foals are gelded or changed to steeplechase. If they are close but don't quite make it, you can still use Legacy to add more foal slots to try get them accepted. Legacy does not work on horses over the age of 20.
