People trying to sell "grass fed" beef will tell you grain is bad for animals
People trying to sell "organic" will tell you GMO's are bad
People trying to sell Fords will tell you Chevy is bad
The TRUTH is cows have been eating grain as long as there have been cows, since "grain" is GRASS seed, and corn is just another grass
This would make sense except I don't believe grass eating cows are usually eating grass seed, they are eating grass. Eating the corn plant is different than eating the seed.
