QUESTION
Prolactin releasing hormone in chicken?
OPTIONS
(A) VIP
(B) FSH
(C) LH
(D) Oestrogen
ANSWER
(A) VIP
EXPLANATION
Vasoactive intestinal peptide, or VIP, is an important hypothalamic prolactin-releasing factor in chickens and helps regulate prolactin secretion associated with reproductive behavior such as broodiness. FSH stimulates ovarian follicular development, and LH supports steroidogenesis and ovulation. Estrogen has several reproductive effects but is not the principal hypothalamic prolactin-releasing factor identified by this question.
