How much does rbST increase milk production?
rBST is carried to the liver where it stimulates that organ to produce Insulin-like Growth Factor (IGF-1), a protein hormone that aids in turning nutrients to milk. IGF-1 is carried to a cow’s mammary gland where it stimulates milk production. Studies have found that rBST can increase milk production 10% to 20%.
