EP 53Guest: Dr. Jim Drackley — Amino acid metabolism and transition nutrition researcher
In this episode of The Dairy Nutrition Blackbelt Podcast, Dr. Jim Drackley from the University of Illinois at Urbana-Champaign shares insights into the vital role amino acids play in the metabolism of transition dairy cows. He emphasizes how providing the right amino acid balance before calving can significantly influence the health and milk production of cows after calving.

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.

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.
