About Anpario

Our promise to you is to formulate products with the highest quality ingredients to help producers raise healthy animals and grow their profits.

Innovators in Animal Health & Nutrition

Anpario, Inc. is led by Dr. William A. Zimmer, D.V.M. President and Director of Research and Development. We are a successful animal nutrition business that was founded in Wisconsin’s dairy region in 1991. Anpario has been supporting producers for over thirty years, and we are proud to manufacture all of our products in Barneveld WI, USA for distribution around the globe.

Notably in 1994, Anpario developed an advanced packaging technique for direct fed microbials and nutritional combination products pioneering them as leaders in the animal health industry. Capsule-In-A-Capsule™ technology earned the company its first patent (5,310,555).

Anpario has continued to expand its product line to include capsules, boluses, pastes, soluble powders, electrolytes, and daily fed additives. Our team of experienced veterinarians and production animal professionals continue to formulate products through research and industry demand.

Innovative Technology

Beyond the Capsule

Anpario’s patented Capsule-In-A-Capsule™ packaging system for direct fed microbial nutritional combinations continues to be the marquis of our product line.

Since 1994, Anpario holds a patent (U.S. Patent 5,310,555) for its critical packaging technique. This innovative technology features the concept of physically separating the live microbial cultures from concentrated micro-nutrients in a combination supplement.

This offers a more complete encapsulation and better dispersion of the microbial culture within the digestive tract. The Capsule-In-A-Capsule™ creates a physical barrier that protects sensitive cultures from damaging compounds (e.g. concentrated trace minerals) allowing the benefits of both technologies in a single formulation.
