What Zeigler does

Zeigler Bros., Inc. is a third-generation, family-owned animal feed manufacturer founded in 1935 and headquartered in Gardners, Pennsylvania, with primary production at its East Berlin facility running approximately 50 tons of feed per day on a 24-hour, six-day schedule. The company specializes in four product lines: shrimp aquaculture feeds (spanning maturation, hatchery, nursery, and grow-out stages), finfish aquaculture feeds (trout, bass, tilapia, marine fish, sturgeon, catfish), pet and zoo animal feeds (koi, aquarium fish, reptiles, small animals, exotic birds, zoo animals), and health and research feeds for biomedical applications. Its core technology is proprietary microencapsulation for liquid larval diets (EZ Larva Ultra, EZ Artemia Ultra) and proprietary probiotic blends (Rescue for Vibrio control, Remediate for water quality), developed through the Zeigler Aquaculture Research Center (ZARC) in partnership with Florida Atlantic University.

Zeigler monetizes through direct sales of its finished feeds, contract research services, and a technology transfer licensing program under which five active international partners produce Zeigler-branded feeds locally in Mexico (two), Ecuador, Egypt, and India. Go-to-market is sales-led via technical representatives deployed to all major shrimp hatchery markets worldwide who conduct daily hatchery visits, complemented by regional distributors in markets such as India, the Philippines, and Saudi Arabia. Pricing is unit-based for premium specialty feeds (e.g., EZ Artemia Ultra at approximately $57/kg), with documented customer outcomes including 33% survival improvements in AHPND challenge trials and survival rate gains from 50-60% to 70-80% in commercial hatcheries adopting Zeigler liquid feeds.

The company has operated continuously for 90 years, serving customers in over 50 countries across North America, Latin America, Asia, the Middle East, and Africa. It pursues regulatory advocacy through industry associations (SATS, AFIA) supporting expanded US domestic aquaculture. Zeigler has no disclosed venture capital, private equity, or institutional ownership, and three employees have been recognized for over 40 years of service, indicating organizational stability.
