Zeigler Bros., Inc. (ZBI) is a global leader in the research, development and production of nutritional solutions for the aquaculture, pet/zoo and lab/biomedical industries.  Founded in 1935, ZBI is a privately owned family business currently operating under the direction of a third generation of the Zeigler family.

Much of ZBI's R&D efforts focus on the aquaculture industry which it has pioneered nutrition based solutions for since the 1950's.  This work has helped advance industry development and supported its growing role in feeding our growing global population.  ZBI also works closely with State and Federal Institutions and has played an important role in supporting the advancement of biomedical research by providing custom diets tailored to meet the demands of researchers.

Manufacturing feeds from as small as 10 microns to as large as 19mm, ZBI has a wide range of capabilities and decades of expertise in the formulation and production of specialized feeds.  The company's ability to address unique problems and support its clients growth has allowed the company to expand its presence on a global scale.
