No rbST hormone made with milk from cows raised without added rbST hormone (No significant difference has been shown between milk derived from rbST-treated and non-rbST-treated cows). 20% larger slice (Big slice dimension versus regular sized Kraft natural cheese slices). For a more flavorful sandwich. Bigger flavor in a big slice. For over 100 years, Kraft has been making the cheese your Family Loves. So, no matter how you like it, we've got a cheese for you. Family greatly.
