While there is still opportunity to further fine-tune the fat budget in our rations as research is devoted in this area, current tools give greater insight as to what strategies are working and which need further adjustments. Who knows, maybe someday balancing our rations with fat will be as easy as balancing that checkbook.

As supplemental fat costs remain high and at times product consistency comes into question, dairies and their nutritionists' interest in high-oleic soybeans has been soaring.

For the rest of us that don’t have that technology on hand, there are still plenty of ways to monitor early lactation performance to help us better understand the impact of the specific fatty acids we are feeding – specifically, body condition scoring from pre-fresh to fresh, monitoring NEFAs or BHBAs and tracking first butterfat trends in your herd management software to detect any significant changes in fat mobilization.

Let’s walk through the main fatty acids found in dairy diets and talk specifically about the signals they are sending beyond being utilized for energy. While they may seem complex, the stakes are high in understanding their roles as there is a rare function of the cow that is not impacted by fatty acids. 

Let’s play a simple word association game. When I say “milkfat,” what do you say? Palmitic? That’s what I’d expect 80% of you to say if we were having this conversation in person.
