Evaluation Of Lighter Density Fraction From Dried Distillers Grains With Solubles As A Feedstuff For Ruminants, Jonathan Michael Greene
Evaluation Of Lighter Density Fraction From Dried Distillers Grains With Solubles As A Feedstuff For Ruminants, Jonathan Michael Greene
Theses and Dissertations
The objective of this study was to evaluate the lighter fraction of DDGS as a possible feedstuff for cattle. To accomplish this, a digestion trial was performed to determine nutrient digestibility and crude protein retention by steers consuming the lighter fraction of DDGS. Steers received L, a diet containing the lighter fraction of DDGS, D, a diet containing whole DDGS, or C, a control diet. Steers receiving L consumed less DM than steers receiving D and C. CP retention and digestibilities of DM, OM, ash, NDF, ADF, HC, and energy did not differ among steers in different treatment groups. Fat …
In Vivo And In Vitro Nutrient Balance And Assessment Of Pcr And Biophotonics As Techniques For Evaluating Ruminal Bacteria, Adam I. Orr
Theses and Dissertations
To better understand the facets of nutrient utilization, a series of in vivo and in vitro studies were undertaken to elucidate the effect of supplementation on utilization of moderate-quality bermudagrass hay and to identify mechanisms to evaluate the role of rumen bacterial populations on feedstuff utilization. A digestion trial was conducted using 6 ruminally cannulated steers receiving bermudagrass hay supplemented with soybean hulls (HULLS), cracked corn (CORN), or soybean hulls and cracked corn (MIX; 75% and 25%, respectively) in a 3x3 Latin Rectangle arrangement. Additionally, ruminal fluid was continuously cultured using the BioFlo® 110 fermentation system to evaluate the in …
