<center> The price of the grass-fed is going to be a bit more for the consumer, but they are showing that they aren't afraid of paying it. The grass-fed cows require more room for grazing naturally and this takes more room than feed lots and common factory farming. It is no coincidence that when the cattle is farmed in a more sustainable way, the cattle ends-up having more nutrients. </center>
