QUESTION
Which one of the following groups of hormones can be used for the therapy of ovarian cysts in dairy cows?
OPTIONS
(A) Estrogen and FSH
(B) GnRH, PG and hCG
(C) Oxytocin and prolactin
(D) Testosterone and Corticoids
ANSWER
(B) GnRH, PG and hCG
EXPLANATION
GnRH, prostaglandins, and hCG have complementary roles in treating bovine ovarian cysts according to cyst type. GnRH induces endogenous LH release, hCG supplies LH-like activity, and PGF2alpha lyses responsive luteal tissue. Estrogen and FSH are not the preferred general therapeutic pair, oxytocin and prolactin do not correct the main ovarian disorder, and testosterone with corticosteroids is not the standard treatment group.
