Zinpro® Availa® Cr
Built Different. Built for Performance.
Zinpro Availa Cr is
Built Different
Chromium has been a part of dairy and beef cattle nutrition for decades but not all chromium is created equal.
The proof is in the performance. Zinpro Availa Cr is built different by design for enhanced performance.
As a bioeffective chromium methionine source,
Zinpro Availa Cr has strong stability and a targeted delivery.

Dairy Performance
Built to support milk, components and profits – through the entire lactation.
Beyond Stress Response
Drive More Milk than Traditional Chromium Sources
Across the lactation cycle, cows don’t just need energy, they need to use it efficiently. Zinpro Availa Cr is built to work with the cow’s metabolism, optimizing glucose utilization so a greater share of dietary energy is efficiently utilized by the animal. This is chromium as a year‑round performance tool, not a short‑term stress fix.
Zinpro Availa Cr supports dairy performance by:
Across decades of global research and 19 peer‑reviewed dairy studies, bioeffective Zinpro Availa Cr has been associated with higher milk production, improved intake and stronger energy balance, with the most consistent responses observed when chromium is fed continuously – from transition through late lactation.
That’s why leading nutritionists don’t treat chromium as a short‑term stress tool. They build it in and keep it in.
Feedlot Performance
Built Different from Start to Finish.
Benefits During Receiving Phase
For a Strong and Healthy Start
Cattle arriving at the feedlot face health and performance stressors such as weaning, transport, co-mingling, handling and changing environmental conditions. Including Zinpro Availa Cr in receiving diets helps improve health, performance and profitability by providing essential nutrients that your cattle need to quickly recover from any challenge.
Research shows that adding Zinpro Availa Cr to receiving diets results in a strong healthy start through:
Benefits During Finishing
Heavier Weights are Within Reach
Success in the finishing phase requires cattle to add carcass weight quickly and efficiently while avoiding common problems associated with immune challenges and stress. Research has proven that animals fed Zinpro Availa Cr absorb more nutrients and perform significantly better while on feed, resulting in improved efficiency and greater harvest weights.
Cow-Calf Performance
Built for the cow. Built for the calf. Built different.
Benefits for the Cow and the Calf
For Reproductive Success and Calf Performance
Field data has demonstrated improvements in pregnancy rate and adjusted weaning weight when Zinpro Availa Cr is delivered through free‑choice mineral systems — proving it’s built for real-world cow‑calf programs.

FAQ
Frequently Asked Questions
What is Zinpro Availa Cr?
Zinpro Availa Cr is the first FDA-approved chromium methionine for beef and dairy cattle. It provides a bioeffective source of chromium that supports insulin sensitivity, glucose utilization and immune function across the production cycle.
How does Zinpro Availa Cr support cattle performance?
Zinpro Availa Cr helps cattle better utilize glucose by supporting insulin function, which reduces the energy deficit during periods of metabolic stress — such as transition, weaning or feedlot receiving. This can result in improved dry matter intake, milk production and daily gain.
What makes Zinpro Availa Cr different from inorganic chromium sources?
Zinpro Availa Cr uses proprietary metal amino acid complex technology, binding chromium to methionine for enhanced absorption and bioavailability compared to inorganic chromium propionate sources. This means more chromium is actually available at the tissue level where it’s needed.
For what species and production classes is Zinpro Availa Cr approved?
In North America, Zinpro Availa Cr is approved for use in beef cattle (including feedlot and cow-calf operations) and dairy cattle. It is indicated for situations involving metabolic stress, including transition cows, receiving cattle and cattle under heat or environmental stress. Outside of North America, Zinpro Availa Cr may also be available for feeding to other species. Check Product Information Sheets for details.
Is Zinpro Availa Cr supported by peer-reviewed research?
Yes, chromium research includes multiple peer-reviewed studies examining chromium methionine’s effects on insulin sensitivity, immune response and performance in both beef and dairy cattle. Zinpro maintains one of the largest proprietary performance trace mineral research databases in the industry.
How is Zinpro Availa Cr fed and at what inclusion rate?
Zinpro Availa Cr is typically included in a total mixed ration or supplement at levels determined by a nutritionist based on production class and stress level. Consult your Zinpro representative or nutritionist for species and situation-specific recommendations.
