Hormone Supplement Free... Until the Cows Come Home.
Recombinant bovine somatotropin (rBST) is a version of the naturally-occurring protein in dairy cows that is produced through biotechnology. It is used to supplement cows’ natural level of somatotropin to allow them to maintain their milk production for a longer period of time.
Our cows are not given rBST hormone supplements, a.k.a. our McCaffrey’s own milk is not produced with artificial growth hormones.
