Zeigler Bros Inc.

Zeigler Bros Inc. manufactures specialized aquaculture and laboratory animal feeds as a prime contractor to federal agencies, competing predominantly under full-and-open procurement without set-aside protections on the majority of its work. The company is a for-profit manufacturer headquartered in Gardners, Pennsylvania, operating under NAICS 311119 (Other Animal Food Manufacturing) and PSC Q1PD (Forage and Feed). Zeigler Bros holds four significant indefinite delivery contracts anchoring federal work: a $75 million blanket purchase agreement with the Department of the Interior Fish and Wildlife Service through October 2032, a $1.7 million indefinite delivery contract with the National Institute of Environmental Health Sciences for rodent feed through May 2027, a $400,000 USDA Agricultural Research Service contract for fish feed through September 2028, and a recently awarded $350,000 Food and Drug Administration contract for irradiated rodent feed through December 2030 (designated Total Small Business set-aside).

Customer concentration sits heavily with the Department of the Interior Fish and Wildlife Service. The top five funding agencies by combined potential value account for 94% of recent award dollars, led by Fish and Wildlife Service Region 9 Headquarters ($75 million, anchored by the single $75 million BPA), followed by the National Institute of Environmental Health Sciences ($2.4 million across 24 awards), the NIH Office of the Director ($1.7 million across 77 awards), the FDA ($1.4 million across 11 awards), and Fish and Wildlife Service Region 4 ($1.4 million across 49 awards). By award count, Fish and Wildlife Service dominates with 153 total awards across its regional and headquarters offices, and NIH component offices account for 121 awards, but the dollar concentration is skewed by the single mega-vehicle: the $75 million FWS BPA alone represents 86% of combined potential value across the entire portfolio. Recent task-order activity under the FWS BPA includes August 2026 and September 2026 calls to Greers Ferry and Chattahoochee Forest National Fish Hatcheries valued at $78,760 and $46,369.57, respectively, and smaller recurring orders ($30,000 to $75,000 range) to Dale Hollow, Kentucky Wolf Creek, and other hatcheries. Under the NIEHS indefinite delivery contract, Zeigler Bros issues delivery orders for NIH-31 rodent feed at roughly $31,000 to $37,000 per order, with multiple orders per year serving biomedical research facilities in Durham and Research Triangle Park, North Carolina.

Activity has remained relatively stable year over year across the past five years—16 awards in 2022, 10 in 2023, 14 in 2024, 15 in 2025, and 6 in 2026 (reflecting a partial-year snapshot)—with a combined potential value of $87.1 million across 452 prime awards accumulated since 1980. Only six awards with combined potential value of $303 thousand face ultimate completion in the next twenty-four months, reducing near-term recompete exposure; the vast majority of dollars and activity flow through the standing indefinite delivery contracts and the $75 million FWS BPA, which runs through October 2032. The portfolio is 100% prime contracting (451 prime awards, one sub-award), with no significant subcontract footprint. Zeigler Bros operates across 19 distinct customer agencies, with Fish and Wildlife Service and NIH-component offices accounting for approximately 66% of awards by count. The company's capability portfolio centers on firm fixed-price supply of bulk fish feed for national fish hatcheries, NIH-31 and irradiated rodent feed for biomedical research, and customized aquaculture nutrition formulations tailored to specific species and facility requirements—work performed primarily at the Gardners facility with deliveries to hatcheries and research centers nationwide.
