Effects Of Increasing The Energy Density Of A Lactating Ewe Diet By Replacing Grass Hay With Soybean Hulls And Dried Distillers Grains With Solubles, Aimee Wertz-Lutz, Robert Zelinsky, Jeffrey Held
South Dakota Sheep Research Reports, 2006-07
The objective of this experiment was to determine the effects of increasing the energy density of a lactating ewe diet by replacing grass hay (GH) with soybean hulls (SH) and replacing soybean meal (SBM) with dried distillers grains with solubles (DDGS) on ewe body condition, milk production and nutrient composition, and lamb performance. Sixteen 2-year-old ewes were selected based on a common lambing date. All diets contained 60% roughage and 40% concentrate. Dietary roughage source, however varied from completely GH to completely SH, and SBM was replaced by DDGS. Diets were formulated to contain 13.9% CP and an increasing amount …

Effects Of Increasing The Dietary Energy Density By Replacing Grass Hay With Soybean Hulls And Dried Distillers Grains With Solubles On Nutrient Digestibility And Rumen Fermentation, Aimee Wertz-Lutz, Robert Zelinsky, Jeffrey Held

We hypothesize that soybean hulls (SH) and dried distillers grains with solubles (DDGS) can be used in lamb diets to increase dietary energy density compared with a traditional grass hay (GH) and soybean meal (SBM) diet without causing adverse effects on nutrient digestibility and rumen function. To test this hypothesis, four ruminally-cannulated wethers were used in a 4x4 Latin square design to determine the effects of replacing GH with SH and replacing SBM with DDGS on nutrient digestibility and rumen fermentation. All diets were formulated to contain 60% roughage and 40% concentrate on DM basis. Dietary roughage source, however, varied …
