Question 7

(T/F) Mammogenesis refers to the mammary gland development. The processes needed to develop the structure of the mammary glad from birth to lactation.

Answer 7

True

Question 8

(T/F) Lactogenesis refers to the initiation or onset of lactation, including colostrum synthesis and secretion. It marks the hormonal and physiological processes involved from a non-lactating to a lactating cow (functional udder).

Answer 8

True
