• Works on cycling animals
• Very effective in getting anovular cows to cycle
• Works on any cycling, fertile animal in any
  reproductive state

How it Works

• Give cows a shot of GnRH
• A week later, give those cows a shot of PGF (also
  have option of starting a new group on the
  program and giving them a shot of GnRH)
• 48 hrs later give the 2nd shot of GnRH to the
  cows that received the PGF
• Depending on time the shot was given, breed later
  that night or early the next morning (8-18 hrs)
• Only requires shot administration 2-3 days a
  week, unlike heat detection which requires daily
  checks
• Record breeding one day/week, can have A.I. tech
  come that specific day instead of every day
• Spreads out births, so not all due on same day
