Profit is a good enough reason, but grass-fed cattle needs more time to finish-often another winter which means more hay and/or seasonal graze. This equates to more graze/land required per animal (which would be true even if the animal was slaughtered at the same age).Hunter 257W":3dwxr25g said:In my opinion grass fed beef desirability got started by farmers who wanted more profit. It's basically free to let a steer eat grass until they haul it to the slaughter house to butcher and sell. Grain cost's money. When we sold calves for slaughter we fed them alfalfa hay, and either corn we crushed in our hammer mill or sweetfeed from the CO-OP and of course they were allowed to graze all the grass they wanted too. I've never eaten a better steak than what we used to grow. We did this all my life until I was 47 when we sold all the cows.
