Episode Details

Most herds still treat the 1.2 mmol/L ketosis cut-point as a hard line: if a fresh cow tests over 1.2, she gets drenched—no questions asked. The problem is, the economics and the latest research strongly suggest that this blanket rule is quietly draining $25,000–$35,000 a year from a typical 500-cow herd while still missing the cows that matter most. In this episode of The Bullvine Podcast, we unpack why the “treat every cow over 1.2” strategy is outdated, how timing, parity, body condition, and system type completely change what a BHB number means, and what a modern, data-driven ketosis playbook looks like for herds that want both healthier fresh cows and stronger margins.

Key Takeaways

· Why the traditional 1.2 mmol/L subclinical ketosis cut-point was never designed to be a one-size-fits-all treatment trigger.

· How realistic cost-per-case models turn “a few ketotic cows” into a $25,000–$35,000 annual hole in a 500-cow herd’s bottom line.

· The crucial difference between a 1.3 reading on day 5 in a fat, fourth-lactation cow and the same 1.3 on day 15 in a high-output second-calver.

· How global data on subclinical ketosis prevalence redefines what “normal” looks like—and why “normal” is often not good enough.

· A practical, risk-based framework for deciding which cows to test, which cows to treat, and when to simply monitor and retest.

· How to use rumination collars, milk components, and MIR-based ketosis risk traits as screening tools, not automatic treatment engines.

· Why the biggest ketosis gains still come from transition fundamentals—body condition, stocking rate, bunk space, and cooling—not just more propylene glycol.

· How emerging genetic tools like MIR-derived pHYK traits can help build “ketosis-resilient” cows over the next decade.
