You can have two of the exact same cows, but what they are fed will impact the compositions of their beef, and especially the fat that contains much of the flavor and gives meat its tenderness.
Should I buy half a cow?
Many families buy half a cow or another bulk option to save money. When you buy freezer beef in bulk it is a larger upfront investment but saves over time. The average freezer beef order costs less per pound, on average, than meat available at a grocery store.
