Pulsation Ratio of Milking Machine for Cattle
Pulsation ratio of milking machine in case of cattle is:
- 60/40 — Correct Answer
- 50/50
- 70/30
- 30/70
Explanation:
Correct Answer: 60/40
The pulsation ratio of a milking machine for cattle is 60/40 (i.e., 60% milking phase and 40% rest/massage phase per cycle).
Pulsation Ratio by Animal
- Cattle: 60/40
- Buffalo: 50/50 (equal milking and rest phases)
Other Milking Machine Parameters
- Pulsation rate: 60 cycles/min (optimum)
- Ideal vacuum — Cattle: 352 mmHg; Buffalo: 400 mmHg
- Recommended vacuum: 10–15 inches of mercury
- Minimum herd size: 20 animals
- Pulsator = 'heart of milking machine'
Why the Ratio Differs
- Buffalo teats have a narrower streak canal and tighter sphincter, requiring a balanced 50/50 ratio for effective milking.
- Cattle teats allow a longer milking phase (60%) as milk let-down is more efficient.
