“I was a little skeptical”

“We’d had Zinpro IsoFerm in the ration and seen some great results. We got to a point where we ran out, I said let’s leave it out. Three weeks later, milk had dropped off.

It did make the difference. So we do now keep that product in all the time.”

What is It?

Zinpro IsoFerm is a proprietary blend of branched-chain volatile fatty acids (isoacids) that directly feeds the rumen’s fiber digesting microbes to improve fiber digestion and protein utilization.

Why Use It? 

When certain dietary conditions exist, cows cannot produce enough isoacids to meet requirements. Supplementing with Zinpro IsoFerm fills the gap, providing the nutrients needed to overcome these limitations.

When to Use?

For best results, start Zinpro IsoFerm in the close-up period, at least 4 weeks prior to calving, and continue feeding through lactation.

Fuel the Rumen First

What’s the solution to advancing efficiency? Let the rumen do the work.

The branched-chain volatile fatty acids that make up Zinpro IsoFerm improve rumen fermentation by directly feeding fiber-digesting microbes.

Optimize the fermentation process for unrivaled results, enabling flexibility in dairy diets to meet specific producer needs while adapting to forage availability.

Unlock Whole-herd Performance 

Cows fed Zinpro IsoFerm can better partition nutrients when and where they are needed most depending on parity, stage of lactation and reproductive status, taking whole-herd performance to the next level. 

Advance Your Operation 

Smarter Use of Feed Inputs 

Zinpro IsoFerm supports lower protein feeding and provides greater flexibility for feedstuff utilization.

On-farm Sustainability 

Improving feed efficiency is good for the cow, the producer and the planet.
