QUESTION
The temperature of artificial vagina is more important than the pressure it exerts on the penis in:
(a) Bull
(b) Horse
(c) Ram
(d) None of the above
OPTIONS
(A) Only b
(B) Only b and c
(C) Only d
(D) Only a and c
ANSWER
(D) Only a and c
EXPLANATION
Adequate warmth is a particularly important artificial-vagina stimulus for ejaculation in bulls and rams, making the combination of these two species the intended answer. Stallions depend strongly on appropriate pressure and other tactile stimuli as well as warmth. All species require suitable collection conditions, but the question concerns the relative importance of temperature, which favors the bull-and-ram grouping over the alternatives.
