Dairyland Laboratories, Inc. is a family-owned company founded in 1958 as a milk testing lab, now an international leader in feed and forage testing. It provides testing services for feed, forage, water, molds, and mycotoxins, with headquarters in Arcadia, Wisconsin.

Dairyland Laboratories was founded in 1958 by Glen Reit as a commercial butterfat testing lab in Whitehall, Wisconsin. In 1959, it moved to its current headquarters in Arcadia, Wisconsin. Over the decades, it expanded services: in the 1960s, a satellite lab opened in Marshfield; in the 1970s, chemistry mineral analysis for feeds was introduced; in the 1980s, NIR testing for feeds began. In the 2000s, it developed Corn Silage Processing Scores with USDA-FRC, In Vitro NDFDs, and barcoding. In the 2010s, it added fatty acid profiles, ash-free NDFs, and a purpose-built Digestion Lab. In the 2020s, it introduced amino acid profiles, LC-MS/MS mycotoxins, and software as a service for labs.
