Why have cows been injected with proteins?

Answer 1

Cows have been injected with proteins in order to increase their milk production. Proteins such as bovine somatotropin (BST) or recombinant bovine growth hormone (rBGH) can stimulate the cow's mammary gland to produce more milk. This practice is controversial as some believe it may have negative effects on the health and well-being of the cows, and there are concerns about the potential impact on humans consuming milk from cows treated with these proteins.
