EP 165Guest: Dr. Kevin Harvatine — Milk fat synthesis and nutritional physiology researcher
In this episode of The Dairy Podcast Show, Dr. Kevin Harvatine from Penn State discusses strategies to optimize milk fat production in dairy cows. He explains the complexities of dietary fat requirements, feeding behavior, and the biological mechanisms influencing milk composition. Learn how seasonality, cow behavior, and nutritional balance interact to impact milk fat yield.
What you’ll learn
- Milk fat optimization
- Dietary fat challenges
- Feeding behavior effects
- Seasonal nutrition shifts
- Milk fat depression

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.
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.
