We could but it would affect production and prices…. I am all for it I do use grain to train cows but it would seriously hurt my hog production. We have moved to a pasture rotational grazing but use the grains for farrowing and first month of sow feeding her piglets. Also in winter when all is frozen grain would be tough to go without…. we are trying growing a wet marsh root crop for them… also potatoes but we would need a massive root cellar upgrade to store that much for current production of hogs.
We get grain near us with contract for non gmo no glygosphate but not like neighbors are under our control but we try…. we dropped fish meal and soy from pigs food as both are toxic so now only peas oat and barley…. in winter we grow 2 tons of hard red wheat for chickens and turkey to keep warm in winter and egg production . Also some cows on the most bitter days to help with the cold.
Grain for eating is hard to grow here conditions are wrong.
