It would also be interesting to get a metric for pounds yielded per seed planted.

That is assuming you bale the hay. if you don’t harvest this crop but instead let the cattle graze on it, it’s probably hard to get a yield from it.

I would also suggest pounds of meat yielded per seed, but I am guessing you feed them something other than just hay and grasses.

When I mention pounds per seed, I do realize that it will like be some fraction of this number with the number of seeds.

Maybe Seeds per pound would be more appropriate.
