Question

To yield more milk, cow is injected with

• A. Sorbitol
• B. Prolactin
• C. Gonadotrophs
• D. Stilbestrol

Answer 1

The correct option is B Prolactin

Prolactin (also called as luteotrophic) hormone is associated with lactation (secretion of milk from the mammary gland). It is a hormone released by the pituitary gland that stimulates breast development and milk production in women. Therefore, to yield more milk cow is injected with prolactin hormone.

Sorbitol is a sweetener found in some fruits (like apple, pear etc.).

Gonadotroph is a type of basophil in the adenohypophysis (anterior pituitary gland) whose granules secrete FSH (follicle-stimulating hormone) and LH (luteinizing hormone).

Stilbesterol is synthetic estrogen used in hormone therapy, as a post-coital contraceptive, and as a growth-promoting agent for livestock.

Therefore, the correct answer is option B.
