Animal with Maximum Semen Volume Per Ejaculate
View Complete Answer & Explanation
Question (English)
Maximum volume of semen per ejaculate is seen in:
- Boar ✓ Correct
- Stallion
- Ram
- Bull
Explanation:
Correct Answer: Boar
The Boar (male pig) produces the maximum semen volume per ejaculate among domestic mammals — approximately 200–250 ml per ejaculate. This large volume is due to the contribution of massive seminal vesicles (which also secrete inositol and ergothioneine) and bulbourethral glands.
Semen Volume Comparison
- Boar: 200–250 ml (maximum)
- Stallion: 125 ml
- Bull: 5–8 ml
- Ram: 1 ml (minimum)
Practical Implication
- Because of the large semen volume in boars, the AI dose in sows is also 50 ml — the largest among all domestic animals.
- In boars, a corkscrew/spiral pipette is used for AI to navigate the spiral cervix of the sow.
