Worth pointing out that both grain crops and the processing thereof have changed significantly in recent centuries, resulting in a tastier (and generally more nutritious, in the case of whole grains) product. Wholemeal flour used for horse bread would have probably been lower both in protein and digestible carbohydrates right from the start, and that's before accounting for indigestible grit and chaff left in it from the grinding process. Grinding was also less consistent, which further degraded the texture of the finished loaf. The exact same ingredients on paper are fundamentally different today than they were in the past -- sometimes for better, sometimes for worse.
But its attached to Horses only, not Buffalo, Cow, Donkey etc.
Donkeys?
Loyal.
Seems like it'd sort of be like the rocket equation, but more forgiving.
The same law applies to global fuel transport: can you export oil halfway around the planet, on a boat that itself runs on oil? There's a rocket equation hidden in that. But the constants are really good (oil is energy-dense; planets are small); so it's not an important law that's ever-present in economics, in the way the rocket equation is ever-present in space. (Was it ever, in history?)
I read a short story once about a world where oceans were too large for oil-powered ships to cross. Anyone know which story I'm thinking of? It was an impossibly large planet too vast for humans to comprehend, and we could only just scratch the surface exploring small corners of it. I remember it had nuclear-powered ekranoplans.
OK are we talking a Mustang or a Shire or Clydesdale? Carrying the food or dragging a wagon?
I don't know enough about horses but a heavy horse (Shirehorse, Suffolk Punch or Clydesdale in the UK) can drag quite a decent load. Granddad's Clydesdale "Damson" could make a furrow with a plough all day, back in the day - bloody hard work. Ironically, that was in Devon - Scottish horse in Shire land! He got a Ferguson tractor later but they kept the horses as well.
I think we would run out of UK for a single horse load unless doing the full Land's End to John o'Groats (or trying to cross the Irish Sea) but a bigger land might need a re-fuel or two.
He also pointed to Wayne E. Lee's article on grass as a limiting factor in Mongol warfare, which I found very interesting: https://www.historynet.com/mongols-on-the-march-the-logistic...
Even if you just put two 10kg bags of oats in your backpack, that's going to last.
20kg? Soldiers have that much to carry, and often more, with weight of gun, ammo, rations, bedroll, and more... yet march day long.
Ha! Good luck. Horses are masters at sneaking a graze wherever and whenever, the instant you stop paying attention.
You're absolutely right:

> The problem in a nutshell is that anything available to these armies prior to the advent of the railroad that can carry food, also eats food (except for boats, but rivers and coastlines may well not go where you want to go). We may call this problem the ‘tyranny of the wagon equation’ as a number of readers have noticed the similarity to the tyranny of the rocket equation.
If the horse eats 20lbs per day (as noted in the article), say it can barely pull 2000lbs on a good quality cart. So 100 days of food. Then just figure out how far it can go in 100 days.
In one day horses can go 80-160km, but they need rest after a few days of this. So say it can do 50km per day sustained and unweighted, 25km at high weight (early in the journey).
Split roughly in half into weight/unweighted days, we get a total distance of about 3,750km for a self-powered horse.
That's almost Lisbon to Moscow, or almost New York to Seattle.

That earlier submission has the data.

Note how non-steppe horses were too big to subsist on grazing alone !
P.S.: Typically *less* forgiving because it's easier to dump parts of the rocket, especially for a return trip ?
Makes a lot of economic sense - what they don't mention is that horses can get energy from fibre, while people can't, so this is biologically efficient as well as economically.
I gave up shortly thereafter and returned to the glory of old trustworthy maltodextrin-enhanced, vitamin-enriched sliced white bread and found other equally unsuccessful hobbies for those extra 2 hours per day.
Only hard, dessicated bread can be given. But even that is not ideal.
Generally speaking, don't feed animals that are not yours, please :)
A horse raised with or adapted to a more varied diet will be a bit more robust. I've known a horse that was fond of sausage and stripped fruit trees and blackberry bushes at every opportunity, her digestive distress after those episodes was never that serious for her. Bystanders may have suffered some.

>It has been claimed that the restrictions in the earlier act were advocated by those with interests in the UK railway industry and horse-drawn carriages.
>Now the small native ponies of the Steppe can subsist entirely off of grass, but the sort of horses available in the agrarian world are bred too big and strong to eat entirely grass. Their nutrition requirements are too high and so they require feed, at least some 4.5kg of it per day assuming local grass is available along with time to let the horses graze it (during which the wagon is, of course, stopped).
"In pre-industrial England, horses took the place of cars, trucks, and trains."
That sounds weirdly Time's Arrow ...
very interesting
