EP 83Guest: Jacob Copelin — Ruminant nutritionist / milk fat depression specialist
In this episode of The Dairy Nutrition Blackbelt Podcast, Jacob Copelin, a ruminant nutritionist, discusses strategies to mitigate milk fat depression in dairy cattle. He breaks down how oils, fatty acids, and branched-chain amino acids (BCAAs) affect milk fat production and rumen health. Jacob also explores how the new CNCPS model and branched-chain volatile fatty acids relate to balancing BCAAs for optimal milk production.

Adisseo solutions discussed in this topic

RumenSmart™
Ruminally active HMTBa (not a source of metabolizable methionine).
Targets diet-induced milk fat depression by supporting normal rumen biohydrogenation and de novo fatty acid synthesis.

MetaSmart®
Patented ester of methionine hydroxy analogue (HMTBa); pelletable and stable in liquid feeds.
About half is absorbed to supply metabolizable methionine; the remainder supports rumen fermentation and microbial protein — useful where pellets or liquid feeds are the delivery route.
