Provision of Forage Protein Reservoirs to Enhance Utilization of Low-Quality Forages by Beef Cattle: Progress Report

This FY24 BIOAg progress report describes a proof-of-concept project testing “forage protein reservoirs” to help beef cattle better use low-quality, mature pasture grasses. The approach establishes protein-rich legume strips (dryland alfalfa and sainfoin) adjacent to base grazing areas, with access managed through fencing so cattle can self-supplement when pasture protein declines. Two research sites have been selected: the WSU Vetter Farm in Stevens County and Washington State University Department of Animal Sciences acreage near Pullman. Because BIOAg funding was not available early enough for 2024 spring seeding, the project is currently in the establishment phase, with pasture renovation and perennial forage planting planned for spring 2025. The team plans to monitor forage quantity and quality throughout the grazing season and track cattle movement and use of reservoirs via GPS, while also documenting expected biodiversity and wildlife benefits.
