Episode Details

Two herds hit an 18% 21-day pregnancy rate for completely opposite reasons — and the manager watching conception rate can't tell which battle he's fighting.

One herd is missing heats. The other is missing pregnancies. The Bullvine Podcast breaks the 21-day pregnancy rate into its two hidden levers — service rate and conception rate — and shows why the fix for one herd is the exact wrong move for the other. Get it wrong and you spend on hormones a cow will never answer.

What You'll Learn

• Why conception rate answers the wrong question about your herd
• How two herds at 18% can need completely opposite fixes
• Where to pull the real numbers in DairyComp and PCDART
• When Double-Ovsynch earns its keep — and when it's just dressing up a close-up-pen problem
• What a six-point pregnancy rate gain is worth: $18 to $36 per cow per year
• The 30-day repro audit that costs nothing to run

Split your 18% and the diagnosis gets clean: service rate under 50% means fix heat detection first — more hormones won't breed cows that never get bred. Conception rate under 30% points to transition and body condition, not protocols. On Lauber's 2026 numbers, a move from 22% to 28% is worth roughly $9,000 to $18,000 a year in a 500-cow herd. Same number on the screen, very different checkbook decision.
