Three years of cornstalk grazing trials were conducted from 1995-97 to determine the feeding value of a sunflower, feather and blood meal supplement compared to a traditional soybean meal supplement. Analysis revealed no year x treatment interaction in years 1 and 2, so data were pooled. Gains of calves receiving soybean meal (0.97 lb/day) were not significantly different from those consuming sunflower/ feather meal (0.83 lb/day). In year 3, protein sources were evaluated for undegradable intake protein before formulation. Gains were similar between soybean meal (0.19 lb/day) and sunflower/feather meal (0.16 lb/day). A supplement containing sunflower/ feather meal is an acceptable alternative to a soybean meal supplement while saving approximately $50-64/ton.
