From Cows Not Treated With Rbst

This refers to milk from cows that have not been given recombinant bovine somatotropin (rBST), a synthetic hormone. rBST is sometimes given to cows to increase milk production. Milk labeled 'from cows not treated with rBST' is a marketing claim indicating the producer's choice not to use this hormone.

This designation is typically found on dairy products like milk, yogurt, and cheese. It is a choice made by the producer rather than an ingredient added for a specific function. Consumers may choose this type of milk based on personal preferences or beliefs about animal welfare and hormone use.

The U.S. Food and Drug Administration (FDA) has stated that milk from cows treated with rBST is safe to drink. Scientific studies have not shown a significant difference in nutritional value between milk from rBST-treated and untreated cows. The use of rBST in dairy cows is a voluntary practice for farmers, and labeling it as 'rBST-free' is a marketing choice.
