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  ...
