HORTICULTURE

Detailed explanation-1: -It is known that cows receiving supplemental BST consume more feed. Additional feed consumption and milk production are related to the amount of BST administered. Therefore, BST stimulates the cow to produce more milk, which results in increased intake to provide the extra energy required.

Detailed explanation-2: -Why is biotechnologically produced BST given in supplemental doses to dairy cows? To increase milk production.

Detailed explanation-3: -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%.

Detailed explanation-4: -Bovine somatotropin (bST), also known as bovine growth hormone, is an animal drug approved by FDA to increase milk production in dairy cows.

Detailed explanation-5: -Recombinant bovine growth hormone (rBGH) is a synthetic (man-made) hormone that is marketed to dairy farmers to increase milk production in cows.
