Here’s the catch. IOFC only tells us the economics of what’s going into the tank, not what’s going into the cow for good health and reproduction, and impacting the farm’s true profitability. It measures how well we are converting feed dollars into milk dollars. IOFC values today’s milk but ignores tomorrow’s pregnancies.

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.

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.
