Merck Animal Health Works for Cow-Calf & Stocker Operations

We know operations like yours often deal with a lot of unknowns. While we may not be able to help you control the weather, we can help you bring strong, heavy, uniform herds to market. All with a broad portfolio of products and the support you deserve.

No room for error.

As the owner of Mitchell Farms, Travis Mitchell knows the importance of managing an efficient operation. He also knows it can be detrimental when cattle go off feed – which is why he always relies on Vista vaccines to ensure he has healthy animals to sell.

Reaching full potential.

Tommie Rogers, owner of Branch Ranch, drenches his cattle with Safe-Guard every time he works them through the chute. He chooses Safe-Guard because it goes right to the gut, enabling cattle to start getting the most from their feed right away.

Implanting for performance.

Shane Kime believes in taking advantage of all the available tools he can to help put pounds on his cattle. One such tool he swears by? Implants. Ralgro and Revalor-G are two implants that help improve efficiency during the grazing season – each with their own unique use.
