***Beef needs to be 100% grass fed.****
You aught to try some of our local grass fed beef that has grazed on wild onions! You will NEVER say anything bad about corn fed beef again. Feeding corn is also a way to get rid of bad flavors from various weeds and onions.
Feeding cattle on any grain gets rid of Good fats, and replaces them with bad fats, and shortens your life.
