Grain Fed meat comes from animals which are fed grass for most of their lives and then transition to grain-based diets for the remainder of their lives.
In Australia, for cattle to be categorized as grain fed they need to have been finished on grain for a minimum of 100 days in a National Feedlot Accreditation Scheme (NFAS) accredited feedlot.
The diets of feedlot cattle are developed by animal nutritionists and compose of cereal grains (wheat, barley, sorghum), fiber (hay and silage), protein (cottonseed, canola meal and molasses), vitamins and minerals.
Skirt steak is one of the most flavorful cuts of beef. The Skirt is located on the inside of the abdomen wall, next to the Brisket Navel end.
The skirts look a little raggedy but are delicious: more tender than flank but with a similar grain and flavor.
