Remember that a number of stress factors can result in decreased milk production. Therefore it is important to isolate and correct ALL causes. To accomplish this, a team approach is recommended.

1. Keep a notebook detailing problems that occur. Include the time of day, equipment in use, duration and a description of the cow’s reaction.
   
2. Have appropriate professionals thoroughly check your herd’s health, milking, feeding and other dairy management programs. Contact your local Cooperative Extension Office for assistance.
   
3. Thoroughly test the milking system and its components to ensure that they are operating correctly.
   
4. Have an electrician completely check the farm’s electrical system for N-E voltage. If excessive neutral-to-earth voltage is detected, repair or modify the electrical system to reduce it to a tolerable level.
   
5. If an off-farm N-E voltage source is the significant cause, contact your power supplier.
