Sixteen cows grazing smooth bromegrass pasture were unsupplemented or supplemented a 35:65 Synergy:straw mixture. Grazed forage intake was replaced about 50% with supplementation, with no differences in cow performance. In a second experiment conducted over two summers, yearling steers grazing native range were fed a mixture of 70:30 or 60:40 hay:WDGS or 60:40 straw:WDGS. During the first year, all steers fed byproduct-forage mixtures had greater ADG than control steers. During the second year, steers supplemented with byproduct-hay mixtures had similar gains as control while steers supplemented byproduct-straw mixtures gained less. Supplementing WDGS and low quality forage reduced forage intake by 17 to 22% in Experiment 2.
