The essential nutrient that fuels the rumen into the new frontier of dairy nutrition.

Enhance rumen fermentation by directly feeding the fiber digesting microbes, improving fiber digestion and protein utilization. This proprietary technology drives feed efficiency, productivity and profitability.
Our Journey with Zinpro® IsoFerm®
“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 3 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.
Build Metabolic Strength During Transition
Unlock peak performance during the most critical phase of life
Zinpro IsoFerm helps cows adapt to intense physiological changes by supporting liver function, stabilizing energy balance and promoting a smoother start to lactation. It’s a proactive approach to managing stress and setting cows up for long-term success.
Begin supplementation at least 21 days pre-calving to maximize your benefits.
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.
*Average results across whole herd. Results differ by stage of lactation and parity.
Advance Your Operation
Smarter Use of Feed Inputs
Zinpro IsoFerm supports lower protein feeding and provides greater flexibility for feedstuff utilization.
- Allows you to react to varying costs and availability of feedstuffs
- Better utilization of human-inedible feedstuffs and homegrown resources
- Improve neutral detergent fiber digestibility
On-farm Sustainability
Improving feed efficiency is good for the cow, the producer and the planet.
- Produce more milk with fewer inputs
- Reduce inputs for increased profits and decreased environmental impact
