At Ladder Creek Dairy, Tribune, Kan., all employees know the code of the tail chalkings used to mark the cows. And, everyone watches for heats to make sure the cows get bred. Here’s the system used:

  • Blue indicates fresh cows.
  • Yellow means ready for breeding.
  • Orange indicates the cow has been bred once and the date is recorded on the cow.
  • Green means she is confirmed pregnant.

It doesn’t matter which colors of tail chalk you use, as long as everyone on your dairy team knows what each color means.
