Land O’Lakes Purina Feed Calf and Heifer Specialist, Christie Stanley, recommends that producers use ammonia badges, in conjunction with an air quality machine, throughout their calf facilities to assist in detecting ammonia-ridden areas or suspected locations of poor ventilation. Here are a few things to remember when using ammonia badges:

  • These tools are effective at identifying where air movement is poor and ammonia levels are high.
  • The badges can help producers in assessing their calf-housing ventilation to then derive a plan utilizing ventilation management practices to increase air movement.

Ammonia badges should be checked regularly – with the maximum time exposure being 16 hours after they are put in place. Be sure you don’t forget where you put them!
