ZEIGLER BROS INC

Zeigler Bros Inc specializes in the precision manufacturing of specialized animal feed formulations for federal research and wildlife conservation programs. Their core capabilities center on producing high-quality, nutritionally balanced fish and rodent feeds tailored to scientific, aquaculture, and wildlife management needs, including irradiated diets for NIH and NTP research protocols. The company demonstrates technical expertise in feed formulation, batch consistency, contamination control, and just-in-time delivery for time-sensitive biological studies. Key differentiators include their ability to produce custom pelletized and bulk feeds under strict quality standards for federally managed fish hatcheries and laboratory animal colonies, ensuring compliance with biological research integrity requirements. The contractor maintains a strong, recurring relationship with the Department of the Interior, supplying critical fish feed to National Fish Hatcheries across multiple states to support aquatic species restoration and stocking programs. For the Department of Health and Human Services, they deliver irradiated rodent feed and assay-grade nutritionals essential for controlled biomedical research environments. These partnerships reflect a pattern of trusted, mission-critical supply chain support with consistent re-engagement for urgent and routine feed deliveries. Their primary industry focus is within NAICS 311119—Other Animal Food Manufacturing—where they serve the niche but vital segments of federal aquaculture and laboratory animal nutrition. This vertical specialization positions them as a key supplier to government agencies requiring scientifically validated, batch-traceable feed products that meet exacting biological and regulatory standards. Zeigler Bros Inc is a small, family-owned business based in Gardners, Pennsylvania, operating under a 2L entity structure. While they hold no formal government certifications, their consistent performance for high-stakes federal agencies underscores their reliability and adherence to stringent quality protocols in the production of specialized animal feed for public health and environmental stewardship missions.
