Summary

Electrical stimulation during milking showed varying sensitivity in cattle. Low currents (≤5 mA) applied through milk lines did not cause adverse effects but altered production, indicating potential for optimized milking practices.

Area of Science:

  • Dairy Science
  • Animal Electrophysiology
  • Agricultural Engineering

Background:

  • Electrical stimulation is sometimes used in livestock management.
  • Understanding cattle response to electrical currents during milking is crucial for animal welfare and productivity.

Purpose of the Study:

  • To investigate the effects of alternating currents delivered through the milk line on lactating cattle during milking.
  • To determine sensitivity thresholds and production impacts of varying electrical currents.

Main Methods:

  • Alternating currents were applied via electrodes in the milk line and a hoof-standing grid.
  • Constant voltages (0-16 V) and currents (≤8 mA) were tested on first and multiple lactation cows.
  • Milking duration, milk yield, composition, and blood cortisol levels were monitored.

Main Results:

  • First lactation cows were more sensitive, reacting at lower voltages (8 V, >5 mA) than multiple lactation cows (16 V, >8 mA).
  • Low currents (≤5 mA) did not induce undesired behaviors but affected milking duration and cortisol levels.
  • No significant differences in milk yield or composition were observed at lower voltages.

Conclusions:

  • Electrical currents of 5 mA or less delivered through the milk line are generally safe for cattle.
  • Specific current levels can influence milking duration and physiological stress responses (cortisol).
  • The required voltages for effective currents present safety considerations for both animals and humans.
