Electrical Stunning Parameters for Small Animals
View Complete Answer & Explanation
Question (English)
Recommended electric current for sheep, goat & pig during electrical stunning is:
- Alternating current of 250 mA & 75 volts for 10 seconds ✓ Correct
- Direct current of 250 mA & 75 volts for 10 seconds
- Alternating current of 250 mA & 75 volts for 30 seconds
- Direct current of 250 mA & 75 volts for 50 seconds
Explanation:
Correct Answer: Alternating current of 250 mA & 75 volts for 10 seconds
For sheep, goat, and pig, electrical stunning uses the Elther apparatus which delivers alternating current (AC) of 250 mA at 75 volts for 10 seconds through the brain.
Key Points on Electrical Stunning
- Type of current: Alternating current (AC) of high frequency and low voltage.
- Instrument used: Elther apparatus.
- Commonly used in: Sheep, Goat, Pigs & Poultry.
- For poultry: electric water bath is used commercially.
Defects of Electrical Stunning
- Splash (Petechial hemorrhages): caused by too high current — appearance of petechial hemorrhages throughout subcutaneous tissue in pigs.
- Missed shock: caused by too low current — animal is not adequately stunned.
- To avoid muscle splashing, animal must be bled within 30 seconds after electrical stunning.
Why Other Options Are Wrong
- Direct current — electrical stunning uses alternating current, not direct current.
- 30 seconds or 50 seconds — the correct exposure time is 10 seconds; longer durations can cause excessive tissue damage.
