Spot on, a 500kg animal will eat 500kg of DM in between 30 and 50 days depending on various factors (especially pregnancy)Hay will be about 85% dry matter. Ewes will eat about 2% maybe 3% of their body weight in dry matter per day. If they are having grass as well then they probably won't eat more than half of that in hay. Not very accurate but that will give you something to work off.
There are some feed calculators on the beef and lamb NZ website that might be helpful too.
That's why smaller animals are more efficient, a 400kg animal has a lot more of that 500kgDM to do something with other than simply stay alive - like making meat, milk, fibre or reproducing.. but her feet are the same dimension.
Her mouth is the same dimension too.
