I don't think "FeedLock" is Purina's product. Appears to come from Agrimprove. This article is from 2020.I can't find an ingredient list quickly to identify what their new "FeedLock" process or ingredient is
"As there is an important need for improved global biosecurity via the feed, Agrimprove have recently developed FeedLock. The product is a patented mixture of medium chain fatty acids (MCFA) with proven effect on viral transmission via the feed.
The product is able to neutralise viruses in infected feed and this way safeguard the animal from being infected through this pathway."

It is not something I was looking to purchase.I wouldn't feed it to my birds, much better options available at the likely price point.
I more curious about what "it" is and it's effectiveness. To me it looks like more of a scratch product. I do think commercial operations could benefit if it works well and does no harm.
