Founded in 1935 by brothers Ty and Leroy Zeigler, the company originated as a local producer of poultry and livestock feeds. In 1967, Dr. Thomas Zeigler (son of Leroy) assumed leadership as President and changed the strategic direction from commodity feeds to emphasis on research and development of specialty animal and aquatic diets. Today, as Zeigler embarks on its 3rd generation of leadership, the company continues to develop new and innovative technologies for specialty markets. Utilizing core competencies in R&D, nutritional formulation, and process engineering, Zeigler currently manufactures over 300 products and exports to over 50 countries around the world.
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.
In the late 1960's Dr. Tom Zeigler, transitioned the company from a manufacturer of farm feeds to an internationally recognized producer of specialized animal diets. Beginning in the 1980s, the company began licensing nutritional and manufacturing technologies globally under the Zeigler brand.
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.
