Bovine Somatotropin (BST)

Bovine Somatotropin (BST) is a synthetic hormone that mimics a natural hormone produced by cows to stimulate milk production. Farmers may use it to increase the milk yield of dairy cows, which can help meet demand and improve farm profitability. While some studies suggest BST-treated cows produce more milk, there are debates about its safety for animal welfare and human health. The use of BST is allowed in the United States but banned in several other countries due to concerns. Consumer choice often leads to products labeled as BST-free.
