Abstract
Six ruminal and abomasum-cannulated steers were randomly assigned to a 6×6 Latin square arrangement of treatments to determine the influence of various supplemental energy sources on intraruminal fermentation and protein metabolism. Approximately 60% of the energy was provided by sorghum silage. Supplemental energy sources were soybean meal plus ground shelled corn, soybean meal plus soybean hulls, corn gluten feed, wheat middlings, 50% corn gluten feed plus 50% soybean hulls, and 50% corn gluten feed plus 50% wheat middlings. Mixed diets were fed once daily.Additions of supplemental energy sources increased intakes of NDF, ADF, hemicellulose, and cellulose compared with intake on the soybean meal plus ground shelled corn diet. Diets containing corn gluten feed had the lowest reticulorumen digestibilities of NDF and ADF and the highest total tract digestibility of hemicellulose. Ruminal NH3, propionate, isobutyrate, isovalerate, and valerate concentrations were greatest for diets containing corn gluten feed. Calculated ruminal escape of dietary CP for the respective supplemental energy sources were 24.2, 30.4, 28.3, 8.0, 28.7, and 16.3%.
