More than 85% of the EPA and 75% of the DHA in calcium salts of fish oil never make it past the rumen. One Midwest herd ran the chemistry — and stopped pretending.

A 500‑cow Midwest freestall had DCAD dialed in, rumen‑protected methionine in close‑up and fresh rations, and a fat blend with fish oil hitting the mixer every day. Their fresh‑cow sheet still wouldn't move. This episode of The Bullvine Podcast follows the moment Cornell's Bauman lab data forced one question: why do nutritionists demand 75–85% bypass on methionine and let omega‑3 walk in with 15–25% bioavailability?

What you'll learn:

Why the calcium‑salt chemistry that protects palmitic fails on EPA and DHA
How $26,000 a year in above‑benchmark transition disease hides in plain sight
The 4‑lb summer milk gap intake drops can't explain — and what it costs at $16.16/cwt
Cost per gram delivered: ~$0.06 vs ~$0.03, and what flips the math
The 30‑day supplier audit any herd can run before changing a pound of ration
Why third‑ and fourth‑lactation cows pay the inflammation bill first

Why this episode matters: Stack above‑benchmark RP, metritis, DAs, and a 4‑lb summer inflammation gap, and a 500‑cow herd is sitting on $50,000+ a year in avoidable drag — without a single clinical train wreck. The episode lays out McFadden lab co‑supplementation work, Dairy UP lipidomic findings on parity 3+ cows, and four honest decision paths from supplier audit to paired on‑farm trial.
