EP 42Guest: Dr. Lucas Rebelo — Methionine and milk fat researcher
In this episode of The Dairy Nutrition Blackbelt Podcast, Dr. Lucas Rebelo discusses the impact of methionine on milk fat production. Dr. Rebelo elaborates on how methionine upregulates enzymes that promote fatty acid synthesis, particularly in Holstein cows. He also touches on the challenges and future research directions in this area.

Adisseo solutions discussed in this topic
Smartamine® MAX
The newest member of the Smartamine® rumen-protected methionine family.
Rumen-protected methionine option for herds balancing metabolizable methionine. See the brochure for specifications.

Smartamine® M
Rumen-protected methionine (pH-sensitive coating releases methionine in the abomasum).
Supplies metabolizable methionine — typically the first-limiting amino acid in North American dairy rations — to support milk protein and fat yield, health and reproduction.

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.
