using improved oak varieties vs chestnuts

Question to all the tree people.

I've noticed that broad acre permies like Mark Shephard and Grant Schultz gravitate towards using chestnut trees.

My question is why aren't selected and improved oak trees used more often? Like the ones found at this nursery https://www.nuttrees.com/

In my context (central Missouri) oaks grow everywhere and seem like they would be an excellent fit, to have ones that produce low tannin acorns every year.

are chestnuts better feed? or produce more? what am I missing?

chestnuts produce a lot faster and need a lot less work to have a saleable product. chestnuts are also a more established product in general. some people still need convincing that acorns are food at all, let alone good food.

but plant oaks too! they deserve their supporters as well! i don’t see any reason not to grow both.

Good points Greg.
I was thinking mostly used for pig fodder. But your points about established market and general acceptance make perfect sense.

There has been at least one production  orchard consisting of oaks with chestnut grafts.
I want to grow dwarf chinkapin oak,  which produces low tannin acorns within a few years of planting.
So far I've been afraid to pull the trigger on buying them.

if we’re talking pig forage, i don’t think you even need to go for especially low-tannin oaks. pigs aren’t as picky as we are about that. for pigs i’d want to aim for the really high production ones, like sawtooth oak. they grow relatively fast for an oak and are super productive - i see them recommended for wildlife/deer forage, and it’s the main species used in one of the few places with something of an industry of acorn foods - korea.

chestnuts will still produce way sooner, though. generally 8-12 years from seed, and sometimes sooner.

Recieved 2 chestnut oaks instead of chestnuts on an order maded in 2016.  The oaks are 2x the size of the chestnuts planted at the same time, appear less bothered by pests, and made their first (unsucessful) attempts at acorns this year.  I can certainly see the potential for livestock feed.  I've never tried eating acorns of any variety.  If they work out, I will be pleased.  The more diversity the better!
