I had this idea for an upgrade to fluffy formula. Genuine bottled fluffy milk. How is this milk acquired? Not from normal mares, of course! That would be inefficient. From genetically engineered wetnurse fluffies!
Specially designed fluffies meant to have almost all the energy they consume go straight to milk production. Since they’re not meant to ever be revealed to the public, no resources are wasted on giving them fluff, functioning limbs, or anything beyond fat storage and milk production.
They’re hairless, blind, deaf horrors that spend their lives with tubes down their throats for food, and up their ass for shit. No one knows if they can talk, as the tubes go down the throat a good week before they’d hypothetically be able to.
I actually had a dream about exactly this kind of thing, just a struggling faceless husk hooked up to a slough of cables and hoses pumping in TPN and hormones and pumping out milk and waste.
The really boring bitch answer: shipping favors lightweight powder that you mix with water as the customer. The amount of space and weight fluid bottles take in a shipment is just too much more for companies to want to do cool things.
Remember, corporations only care about profit and we’re all enfie babbehs and poopie babbehs.
Im usually pretty iffy on designing a new fluffy species like that. I think its cuz I feel that irl it wouldnt make much sense unless the milk is being sold for human consumption. If its just to feed foals then I dont think theres enough demand for a company to bother creating the subspecies when they can just pillow a mare and give her the stuff they give to dairy cows to make her make more milk.
To be honest, it’d be just a nurse mare - a mare who pretty much kept in the stage of her body keep making milk with non-stop foals on her. Along with that, it just sound like more steps to de-leg and defluff a mare to get the same results.
The concept isnt new but I mean that in the setting I dont see a company going through the R&D effort to genetically design a new breed of fluffy just for their milk. Too much money and time to do that when you can just pillow a mare and hook her up to a milking machine.
