QUESTION
The best site for deposition of cryo-preserved bovine semen preserved in 0.25 ml straw is?
OPTIONS
(A) Mid cervix
(B) Body of the uterus
(C) Uterine horn
(D) Fornix vagina
ANSWER
(A) Mid cervix
EXPLANATION
In the conventional recto-vaginal artificial insemination technique taught in many Indian veterinary and animal-husbandry texts, 0.25 mL frozen bovine semen in a straw is deposited at the mid-cervix. Indian instructional material specifically describes mid-cervix as the ideal site for deposition of a 0.25 mL frozen semen dose. The fornix vagina is unsuitable because semen deposited there has poorer access to the uterus, while deposition directly into the uterine horn is not the standard routine AI technique. Although uterine-body deposition is recommended in several modern AI protocols, for this examination and the Indian textbook convention, option (A), mid cervix, is correct.
