True or False: The hormone bovine somatotropin (BST) increases milk production in cows.

Bovine somatotropin (BST) is a naturally occurring hormone produced in the pituitary gland of cows that plays a significant role in regulating metabolism and promoting growth. When administered externally, recombinant bovine somatotropin (rBST) can enhance milk production in dairy cows. This increase occurs because BST stimulates mammary gland growth and improves feed efficiency, ultimately leading to greater milk yield.

The hormone has been used in the dairy industry to help increase productivity, allowing farmers to produce more milk from the same number of cows. It is important to note that while BST can increase milk production, its effectiveness may vary depending on several factors such as the cow's health, age, and overall management but the assertion that BST increases milk production stands correct in the context of its application in the industry.
