Disease Prevented by AI with Frozen Semen
View Complete Answer & Explanation
Question (English)
By Artificial insemination (A.I.) with frozen semen, which of the following disease can be prevented?
- Vibriosis (Campylobacteriosis) ✓ Correct
- I.B.R. (Infectious Bovine Rhinotracheitis)
- F.M.D. (Foot and Mouth Disease)
- Trichomoniasis
Correct Answer: Vibriosis (Campylobacteriosis)
Vibriosis (caused by Campylobacter fetus subsp. venerealis) is a venereal disease transmitted only through natural mating (coitus). Because AI with frozen semen eliminates the physical contact between bull and cow, Vibriosis can be prevented through AI.
Why AI Prevents Vibriosis Specifically
- C. fetus subsp. venerealis lives in the prepuce/sheath of the bull and is transmitted to the cow's reproductive tract during natural service.
- With AI, no physical contact occurs — the organism cannot be transmitted.
- Similarly, Trichomoniasis (caused by Tritrichomonas foetus) is also a venereal disease preventable by AI.
Diseases NOT Prevented by AI
- IBR: Transmitted via respiratory secretions and nasal contact — not a venereal route.
- FMD: Highly contagious via aerosol, contact, fomites — AI does not prevent spread.
Key Rule
AI with frozen semen prevents venereal diseases (Vibriosis & Trichomoniasis) because it eliminates bull-cow genital contact. Answer here is Vibriosis as the single-best option listed.
