back to what i was doing

so....
i think, you guys & girls, will hate me

if i asked around about the vanilla cattle and milk..... we can only get 1 resource out of a livestock. since we got many cows that gave milk , i wished to make cattle and give something else : fertilizer

but since the vanilla cattle is still used to give milk by other mods.....
i was wondering if i do instead .....
new crop just to get hays...
and we use hays to feed a stable of horses...
and the stable will need hays and make fertilizer as return...
and the greenhouse will use fertilizer along with water to get seedlings...
and the greenhouse will use seedlings and more water and give food ??
i know thats alot of operations.... a big chain but if i tweak the numbers so with 1 crop of hays we get like 4 or 5 crops as amount of food ....
it can also maybe change a bit the look of the landscape to see hays all around ? <= statement under reserve on how often we can see cylinders of hays roaming around ^^
